A Modern Railroad-Disinfecting Plant

(Eine moderne Eisenbahn-Entwesungsanlage)

by Dr. G. Peters

translated by F. P. Berg from: Anzeiger für Schädlingskunde, Vol. 14 (Berlin: Verlagsbuchhandlung Paul Parey, 1938), Heft 8, pp. 98-9.


In Heft 3 of this journal from the previous year, we summarized the development over the years of methods for fumigating railroad trains with hydrocyanic acid. Within that discussion, several fumigation tunnels were also mentioned, some of which are in operation in the Balkans and some in Central America. Finally, the application of vacuum plants (Vakuumanlagen) for this purpose was also discussed. In the meantime, another quite interesting, larger fumigation chamber for railroad cars which deserves a special discussion has been built and brought into operation in Budapest.

Figure 1: Railroad Fumigating Plant in Budapest (empty with doors open).


The facility which was proposed by the Hungarian State Railways and constructed in collaboration with the German Company for Pest Control, G.m.b.H. [DEGESCH], Frankfurt on the Main, is special because it is the first time that a fumigation chamber on the largest scale has been created and tested with a circulatory system. The circulatory arrangement (Kreislaufführung) for mixing air and gas is known to have great advantage[s]: on the one hand, the gas evolves [is driven out of the granules in the cans of Zyklon-B] more easily and, on the other hand, the gas is distributed faster.1 We need not examine the construction of such circulatory plants in great detail--it is sufficient to point out that: circulatory gas-generating equipment (Kreislaufvergasungsapparaturen) allows one to easily and safely handle even the most poisonous substances; furthermore, by means of a repeated exchange of the entire air-gas mixture during the first hour of fumigation, the concentration of the air-gas mixture is ideally distributed so that the losses [of cyanide] due to adsorption are minimized; and finally, because of the special design of such chambers, they can be vented with the doors closed. In this way the circulatory principle (Kreislaufprinzip) encompasses technical improvements which increase the likelihood of success of the fumigation procedure while, at the same time, significantly reducing the safety hazards. It was these advantages which apparently also motivated the Hungarian State Railways to make the first attempt at the construction of such a facility in Budapest. Already after several months of almost uninterrupted use of the chamber, the elegance and safety of this facility have been clearly recognized.

The plant is used for fumigating railroad passenger coaches as well as for disinfecting freight cars. For the first type of application, one is concerned with bugs (Wanzen) and vermin whereas for the second type of application, one is especially concerned with the extermination of chicken mites (Hühnermilben). The transport of chickens in Hungary leads to a heavy accumulation of mites in the cars used for this purpose which are, as a result, frequently infested, not only within the railroad cars themselves but, also, on the exteriors of the railroad cars. It was precisely for this reason that one had to construct a fumigation tunnel; otherwise the fumigation of only the interiors of the railroad cars would simply not have eliminated these pests.

    The accompanying photographs give some idea as to the exemplary manner in which the fumigation plant was actually constructed, structurally as well as technically. (Only the construction of the large double door with countless screw joints is unnecessarily cumbersome.) The gas-tightness of the steel-reinforced concrete chamber is so great that when the blowers are turned on inside the closed chamber, the pressure drops almost 200 mm H2O which is truly remarkable for a room with a volume of 350 cubic meters. The venting as well as the circulation of the air-gas mixture is achieved by a powerful medium-pressure blower which is sized large enough to permit 30 complete air-exchanges per hour. For this purpose, the supply and return ductwork are arranged diametrically, one above the other, (see Figure 2) with appropriate registers or louvers. For a single fumigation, two cans of Zyklon (see Figure 3) are sufficient. The cans are opened in the "apparatus room" inside special gasifiers which are built into a bypass (Nebenschluss) of the circulatory system so that in just a few minutes, all of the gas is drawn out of the cans so that the cans can be removed totally free of poison.

    During the cold months of the year, the facility is heated by four furnaces so that the minimum temperature of 20-250C. (68-78.20F.) which is necessary for rapid penetration can be achieved quickly and maintained for weeks at a time. The furnaces were specially designed by the Hungarian Korompai, a member of the Board of Public Works (Baurat). They require no service or maintenance for days at a time and are unusually economical to operate.

    The chamber operates almost without interruption and is at this time probably the most modern facility of this type.

Transportation Hygiene and Disinfestation

(Verkehrshygiene und Schädlingsbekämpfung)

by Dr. Ludwig Gassner, Frankfurt on the Main

translated by F. P. Berg from:

Gesundheits-Ingenieur, Vol. 66 (1943) Heft 15, pp. 174-76.

   


One special area within the field of pest control for the control of carriers of disease pertains to the disinfestation of transportation vehicles. In this category, the most important above all else are the railroads. Practically all of the civilized nations in the world have dealt with the problem of disinfecting railroad cars, but generally only in a theoretical sense. As a rule, it is less often disinfection, in other words, the sterilization or killing of bacteria which is meant than the extermination of vermin for which, since it is primarily insects and their brood which is involved, the word "disinsection" was coined. Even in Russia, this question was discussed more than 20 years ago1 and one arrived at the only correct conclusion that, on the basis of all experience up to that time, the disinfestation of railroad cars could only be done thoroughly if one used hydrocyanic acid.

    Ever since World War 1, this substance, which is gaseous at room temperature, was used as a standard issue preventive substance (flour moth control in large flour mills). Thanks to thorough preliminary studies and the receptiveness of the responsible German authorities one could no longer disregard this gas for use in the food industry. The prejudices and above all the great fear of the "devastating poison" disappeared. During this period (1916) the first hydrocyanic acid fumigation of a military-hospital train took place in Germany and in a rather makeshift manner which was replaced several years later by the German Zyklon method (absorbed liquid hydrocyanic acid) which reduced the danger for well-trained technicians to an absolute minimum.

    It was and still is true that of all the methods for the killing of clothes lice, bugs and fleas with larvae, pupae and eggs--the goal is achieved most ideally with hydrocyanic acid gas.

    For the practical implementation of such a disinfestation, various approaches to the problem come to mind:

  1. Disinfestation in the open without a cover over a thoroughly sealed vehicle which one intends to reuse.

  2. Disinfestation in the open with a tent cover over the vehicle.

  3. Disinfestation in a gas chamber.

        Within Germany proper there was very little reason for intensive pest and vermin control of railroad coaches and freight cars.2 But the necessity for this was extremely great in several Balkan countries, Spain, Africa and South America where, incidentally, the German methods became predominant. The elimination of disease carriers in the coaches and sleeping compartments often goes hand-in-hand with the extermination of vermin that infest foodstuffs and provisions in freight cars. Of the three methods which have been mentioned, the method which is preferred almost exclusively employs fumigation chambers.

    Figure 1: Facility in Budapest--Interior View


    Probably the oldest published work on this subject was by Schumacher and is entitled "The Disinfection of Railroad Coaches in Repair Shops."3 In Europe such chambers exist in Potsdam, Cologne-Nippes, Posen, Zagreb, Budapest, Bucharest, Sarajevo, Skoplje. The most ideal arrangement is a circulatory system, which can handle even the most poisonous substance with ease and safety. There are also fumigation tunnels, as in Sarajevo for example, which can handle two railroad cars at a time. Of importance is the rapid and uniform distribution of the gas by means of circulation ducts or blowers, at least partly because the speed of the operation is the very key to its efficiency. Only relatively small amounts of the gas are necessary for this work. A Zyklon container with 500 grams of hydrocyanic acid is already sufficient to delouse a modern express passenger railroad car (approx. 200 cubic meters); larger containers are used in the fumigation tunnels where 500 to 1000 grams of hydrocyanic acid, depending upon the temperature, are used per 100 cubic meters of interior volume--the higher the temperature, the greater the effect of any given amount of the gas.4

    Figure 2: Schematic of a Circulatory Facility

    Another hydrocyanic acid method which has recently been used here and there is the spreading of Calcid, a powdery cyanide of calcium (zyanwasserstoffsäurem Kalzium), which reacts with the moisture in the air and gives off quantities of hydrocyanic acid but which leaves traces behind whose removal is time-consuming. Because of the greater amounts of material which are needed to achieve an effective gas concentration, one must also expect longer fumigating periods (längere Arbeitsbelastung).

        It should also be emphasized that the use of hydrocyanic acid gas, on passenger railroad cars for example, has absolutely no effect on upholstery, leather, fabrics, metals, paints and interior furnishings of any sort.

        On June 23, 1942 the Reich Ministry of Transport issued an unpublished decree to plant managers and others which specifies the measures to prevent the spread of typhus (Disinfection of passenger cars and freight cars). Only a small number of disinfection substances are mentioned.

        In 1941 a decree was published regarding the removal of contagious substances from trains and ships engaged in the transport of livestock within the Generalgouvernement [those parts of German-occupied Poland that were not annexed] which specified precisely when and under what circumstances trains had to be immaculately cleaned and disinfected; and also, which chemicals could be used for this purpose. The chemicals which were permitted were primarily a mixture of cresol and sulfuric acid, caustic soda solution, concentrated watersoluble chloride of lime preparations or raw chloramin (Rohchloramin). It can be noted also that a single certifiable cleaning and disinfestation made within the German Reich, would be sufficient [to meet the regulation].

        Dry heat together with vacuum (Unterdruck) has also been used to disinfest railroad cars. This hot air process has, however, not proven itself successful in the long run; furthermore, it only works in stationary chambers, as long as sufficient fuel is available for heating.

        For all practical purposes, the best method for the fumigation of small spaces on ships is probably with Tgas (ethyloxide).

        No less important, but particularly during peace time, are the methods for exterminating rats on ships. It is well known that the rats which exist on every large ocean liner can spread the plague bacillus, the germ of this terrible disease, which lives on or in the rat flea. One used to try to kill off the ship rats with makeshift methods. In America one tried at first to use poison gas. Ever since the International Sanitary Convention which was ratified on June 21, 1926 in Paris by most countries of the world6 this despicable dangerous parasite has been fought in an organized fashion. Of course, one has tried to get rid of the rats, as already mentioned, from ships arriving from countries which may be plague-infested. At this point, the method which comes to mind is the very practical Nocht-Giemsa process (producer gas) which was formerly used in the harbor of Hamburg. The fight against ship rats became a universal responsibility only with the implementation of the international treaty mentioned above which provided for uniform procedures for the control of contagious disease and, of special importance, even went so far as to specify the actual measures for controlling the spread of diseases that are a public menace because of international shipping.

        In Germany one worked a great deal with sulfur dioxide (according to the Clayton Method or through the generation of SO2 from carbon disulfide, Salforkose, and sulfur preparations, etc), but this was steadily replaced by hydrocyanic acid over the years. The spreading of poisonous bait had only limited success on ocean-going vessels because the rodents within the cabins, galleys, and cargo bays were able to find more suitable food elsewhere. The "rat-proofing" system which was introduced sometime ago in the United States of America did not prove itself over the long run.

        This method relied upon simple devices to prevent rats from climbing onto ships at dockside without considering the fact that these animals could also be brought on board with the cargo.

        Regarding ship disinfestation in general, hydrocyanic acid won hands down over the competition. Appropriate personnel for the intended tasks are the exterminators, health inspectors and fumigation companies. The certification of the fumigation results is the responsibility of the harbor authorities.

        Aside from pest rats--laboratory experiments in Algiers have shown that a single rat may at times carry as many as 2500 fleas and each flea can be the host to 5000 pest bacilli7--one must also mention mice (Weilsche disease), lice (typhus), mosquitoes (malaria, yellow fever), and flies (typhoid, dysentery) as carriers of disease on ships.8 With the regular control of the most dangerous parasites, the rats, one is also controlling all other vermin on board as well; of course, this includes bed bugs, fleas and cockroaches.

        Hydrocyanic acid gas kills all vermin including the brood and, because of its great ability to penetrate, is able to fill every space as well as all cracks and hiding places as no other gas available for pest control purposes and, as has already been mentioned, is harmless to furnishings and cargo because of its chemical inactivity.9 Even foodstuffs need to be removed only if they happen to be uncovered liquids. But live animals and plants, photographic products, raw coffee and tea must all be removed from aboard ship. For years hydrocyanic acid has been applied in the form of Zyklon. The ship being fumigated must be cleared of all people except for the ship's watch and must be distinguished until the ship is released by means of a special flag by day and by a particular light by night.

        A few words are still necessary regarding rat elimination from decks with Calcid. On the basis of experience, rats are often present, for example, in the steampipe insulation, under the winches, in the potato bins, lifeboats and similar equipment. For the procedure to be successful, it is necessary to exterminate these as well. Whereas when one is working with Zyklon one simply spreads out the contents of a can upon pieces of paper, on deck one normally uses Calcid tablets [instead] which are ground into a fine powder in a pulverizer and blown onto the locations to be disinfected.

        Regarding the hygienic treatment of ocean-going vessels in German harbors, there is a regulation from the Reich Minister of the Interior dated December 21, 193110 in which the extermination of rats is regulated in Paragraph 12.

        That the field of hygiene for transportation vehicles has been extended just recently to include airplanes is not really surprising since it has been established that dangerous disease carriers can even be carried by aircraft. The danger is especially great when the airplanes land in regions which are still today a constant source for disease.11 In the International Sanitary Treaty for Air Travel of April 12, 1933 (The Hague) a series of preventive measures have been established for the removal of vermin and rats as well as for sanitary services in airports and the possible quarantine of travelers, the treatment of the sick and-- under certain circumstances--the pest control of goods and mail. Foremost among the diseases which can be carried are: plague, cholera, yellow fever, typhus and smallpox. In the treaty just mentioned, the controlling substances are not specified. However, at the conference of the International Sanitary Office in Paris in May of 1937 a report from the Quarantine Commission for Air Travel discussed pyrethrum powder, hydrocyanic acid and other fumigating substances for killing mosquitoes on aircraft and also indicated the toxicity of these gases for humans.

        In reality, it is very difficult to disinfect aircraft with gas even though it has been done in the past and will continue be done again many more times. A fumigation of a covered aircraft (often practically impossible because of the often immense proportions of the wings) or an aircraft in a hangar is possible. However, it is necessary to protect the expensive, important, often oil-enclosed and not hermetically sealed instruments in the cockpit; oils can absorb gas--they can even combine chemically with them.

        Aedes and anopheles, the carriers of yellow fever and malaria, are most effectively destroyed with gas but these species of mosquitoes can also be exterminated with pyrethrum-based insecticides. In the United States one is less particular. Griffiths and Michel12 recommend without any reservations the use of hydrocyanic acid preparations and Carboxide, a mixture similar to the German Cartox which is made from ethyl oxide and carbon dioxide. In South Africa and even North America, airplanes were already treated without any hesitation with Zyklon with special care for the wing interior spaces which could not be sealed. Nonetheless, the use of highly toxic gas (by the natives) in transcontinental air traffic has not yet established itself; similarly, it has not been possible, at least for the time being, to implement the plan to build mosquito-free aircraft.

        Before World War 2 Germany had no special reason to disinfest aircraft for hygienic reasons. However, many experiments had been initiated which could not be completed under the circumstances--otherwise, German discoveries would have certainly pioneered in this field once again.

        It is hardly necessary to mention the de-mothing of automobiles (passenger vehicles) and the fumigation of trucks for the extermination of vermin that infest foodstuffs. Clothes moths, including their brood, as well as other vermin which infest foodstuffs and provisions can be easily neutralized with sulfur dioxide (difficult to remove), T-gas and, most of all, hydrocyanic acid. The methods are, as is apparent from the above, simple and safe; but, these measures play almost no role as far as hygiene is concerned. Delousing of passenger vehicles (carriages, streetcars, boats) is regulated by a decree from the Reich Minister of the Interior of February 13, 1941.13

        In closing, it should be added that [supposedly] louse-infested railroad trains, airplanes, etc., are in reality often quite harmless because there simply may not even be a single louse present. As Rose14 explains, it is not the suspected means of transportation but quite often it is the louse-infested people themselves in close proximity to one another in overcrowded vehicles who are the true source of the lice. In other words, one should not overestimate the benefits to be derived from a totally lifeless transport vehicle.

    The Epidemiology of Typhus in the Generalgouvernement

    (Zur Epidemiologie des Fleckfiebers im Generalgouvernement)

    by Assistant Physician Prof. Dr. E. Zimmermann

    (deceased at the front)

    & translated by F. P. Berg and I. Steinwarder from:

    & Zeitschrift für Hygiene und Infektionskrankheiten, Vol. 123

    (Berlin: Springer Verlag, 1942), Heft 5, pp. 552-7.

       


    Typhus has always reigned as an endemic disease in the Eastern and Southeastern provinces of the former Polish state. This was especially true for the provinces of Wilna, Nowogrodek and Stanislawow. Here during severe outbreaks, about 5-10% and more of the population would fall ill annually whereas in the Western parts of Poland, the disease declined steadily over the years so that it was virtually unknown in the present Warthegau or else occurred only in isolated cases or clusters without any tendency to spread. During the last years before the present war, the pestilence had almost been eradicated within the central parts of the country, just as conditions in the Eastern parts were also improving. That the present wartime dislocations would again increase the frequency of typhus was to be expected since it had always been a typical plague of war, but the magnitude of the reoccurrence in 1940 was many times less than had been expected. If we adjust the number of previously reported cases [for all of Poland] in order to try to get numbers that only apply to the area of the present day Generalgouvernement--obviously, these values will be only rough approximations in order to be able to make comparisons with those for 1940--we get the following.

    Table 1.

    Typhus occurrences per year in the
    present-day Generalgouvernement.
    1919 44,000 1930 320
    1920 34,000 1931 420
    1921 10,000 1932 500
    1922 8,500 1933 680
    1923 2,200 1934 1,000
    1924 1,500 1935 800
    1925 800 1936 740
    1926 700 1937 680
    1927 600 1938 700
    1928 500 1939 ?
    1929 400 1940 7,900

        Obviously, the statistics can not show all occurrences because it can be assumed that, at the very least, the undiagnosed, mild cases were not reported. It is quite possible that the true morbidity rates are actually double or triple the values which have been reported.

        It is well-known that during the world war [World War I], typhus had been widespread on the Eastern front and had caused sickness among our own troops. Then in 1919-1920, the Russian-Polish war came again with great troop movements, refugee treks, food shortages, great poverty and from 1921-1922, the Poles returned in great waves from plague-infested Russia. And so, it is not at all surprising that Typhus exanthematicus developed dramatically at that time. With the gradual consolidation of the political situation, which resulted in an improvement in the general hygienic conditions, the pestilence subsided quickly and steadily until the general economic crisis of 1930-33 with its unemployment interrupted the favorable progress and brought with it another peak in typhus mortality in 1934. After that, conditions improved once again. Although many attempts have been made to try to relate the reduction of the epidemic to the anti-typhus inoculations given by Weigl after 1930, the contribution of these inoculations to the favorable development could only have been rather modest since the decline of the typhus had already begun earlier. According to Weigl, 67,893 persons had been vaccinated but these were predominantly doctors, sanitary personnel, civil servants, people close to patients and others who might be endangered by close contact.

        It was inevitable that troop and refugee movements, in addition to economic difficulties arising from the developments in 1939, would lead to a reemergence of the epidemic but an ever-increasing number of cases in strength could only be expected at the beginning of 1940 since the usual course of the typhus epidemic would produce many cases. At any rate, since the morbidity rate did not increase more than usual in 1940 and since our troops were practically unaffected by the disease, a number of favorable factors were cited: on the one hand, ideological beliefs of our troops resulted in less fraternization with the Jewish population, i.e., the carriers of the epidemic, than during the world war. On the other hand, this war was over too quickly to allow the disease to establish itself and to spread. Additionally, this time the refugee treks came, in contrast to the years after the world war, not from a center of contagion (Seuchenherd), but from the West, from a region which was free of the pestilence.

        Although it was in the nature of earlier population figures and epidemiological statistics in Poland that there are no exact numbers available, nonetheless the Jewish share [(Anteil der Juden) - emphasized as in the original] in the typhus phenomenon has obviously always been rather high. Normally it seems to have been about 70%_80%, but in 1940 the Jewish share in some communities was 95% or even more of all typhus cases. We personally had the opportunity to study an outbreak of the epidemic in greatest possible detail in one town with approximately 30,000 inhabitants of whom about 11,000 were Jews. Of the 303 cases of the illness, 295 were among Jews, i.e., 97% among Jews and only 3% among Poles. For our further investigations it was important that we examined the significance of age of the people in the homes affected by typhus. A total of 3464 Jewish persons, living more or less without any non-Jewish intermingling, were evaluated statistically.

        The mortality of the disease in all these years seems to be surprisingly low. For the years following the world war, the rate was 7%_9% with the exception of 13.4% for 1920. Thereafter, the mortality rate decreased to 5.2% in 1938 and in 1940 to 5.6%. However, many mild cases may not have been reported so that the hazards of the illness might, in fact, be even less.

        If it seemed as if Jews were especially resistant to typhus, that picture changed as soon as age was taken into consideration (Table 2, Column a). More than half of all the cases of illness which were observed by us were of persons less than 20 years of age, and one quarter of the total number of cases occurred among persons between 16 and 20 years of age. It should not be necessary to explain any further that the usually favorable course of the disease for this age group lessened the mortality rate in general. Contrary to the widespread opinion that Jews are less susceptible to typhus, the mortality rate of approximately of 5% for the 16 to 20 year old group and 25-30% for middle-aged adults (Table 2, column C) is absolutely normal. This fact appears favorable only because the typhus of 1940 affected primarily children and adolescents. Perhaps this had also been the case in former years with the exception of 1920 and its higher death rate.

    56-60 2 5.84
    61-65 1.4 4.0

        The high percentage of adolescents among the ill suggests an immunity of adults which might have been acquired during the epidemic years following the world war which protected them now even though typhus usually produces only limited immunity. This influence can only be examined more closely if we calculate the percentages of the affected within their respective age groups. To begin with, we can make the following estimate. The Jewish population over 20 which might have become immune after the heavy epidemics following the world war could not be more than 1.2 million in the Generalgouvernement. Assuming that 250,000 Jews had become ill at that time, then one can estimate very roughly that 25-30% of those who are 20 years old today would be immune while all the others in this age group and practically all adolescents in 1940 would have been susceptible. Our age calculations (Table 2, Column B) gave indeed few differentials which could have been appraised as partial immunity of the 20-year olds. The percentage of the 16-20 year olds is conspicuously high because 77 out of 369 from the age group fell ill, while the 15 year olds might either have an inborn immunity or the illness developed abortive, which is typical at this age, and remained undiscovered. It is, however, a fact that in the beginning of 1940 enough people susceptible for the epidemic were available to spread the ground for epidemics during the next year.

        In the area for which we were responsible--about a quarter of the Generalgouvernement-- according to statistics and reports from doctors, typhus had occurred only sporadically before the year 1940. This was also evident from the fact that the younger people among them were not personally acquainted with the clinical facts of Typhus exanthematicus. Only a few towns showed an unexplained slight increase of morbidity during 1938 and 1939, while only only half a dozen cases showed up in towns with 10,000 to 20,000 inhabitants.

        Thus, the winter of 1939/40 started at first with only a very limited number of cases. Only in 1940 did isolated cases occur at the same time or quickly following each other, mostly in small towns, in many cases in villages which had until now been untouched by the pestilence and which were far removed from each other. Of course, one imagined that a [single] carrier of typhus infected lice might have caused the outbreak because of his wanderings, but this explanation remained unsatisfactory for all practical purposes. Very often the villages affected were 100 to 200 kilometers apart and it seemed unlikely that at a time of unusually severe cold with masses of snow on the ground that a person might have gone wandering over such great distances. It seemed much more likely that several virus carriers were wandering around who had sought shelter because of the weather conditions and had left the infection behind. Beggars and tramps have traditionally been the most important carriers. But it also has to be remembered for the first cases of an epidemic that a virus can remain alive in the lice excrements on clothing for a long time and that the reuse of winter clothing might result in new infections. Experiments conducted by Weigl showed that the virus is capable of infecting for several months.

        After only a few individual cases had occurred in January and the beginning of February, the interconnection of which was unclear, the further course of the pestilence could be observed accurately. Sometimes the illness disappeared by itself, even without special protective measures being taken. In other cases, there were cases within the vicinity or greater outbreaks, these only in towns and often it could be verified how the typhus had been carried from one community to another. Very often, but not always, beggars and vagabonds were involved, but the principle cause was the lively Jewish wandering which still prevailed at that time. The elders of the Jewish communities were supposed to care for these wanderers, but this care often failed since Jewish solidarity was definitely not always as dependable in crisis as it should have been (Notfest) to include practical measures of disease prevention. Arrivals were very often considered and treated as unwanted guests in the communities. They were quickly urged to go away again with a small contribution and thereby promoted the wanderings. In other cases they were housed in mass quarters which quite frequently developed into terrible epidemic hotbeds. In extreme cases only 3-4 square meters of floor space and even less were made available per person.

        Smaller communities with less than 7000 inhabitants and the flat countryside were generally at first hardly affected by the epidemic. Only in April and May, when under the influence of countermeasures and other factors the Typhus exanthematicus started to subside in the cities, several small farming communities were affected, even if the occurrences were limited to isolated cases. Here too, it was mostly Jews who became ill, but the Polish share was greater than in the cities. With regard to the unpleasant result that the typhus spread to the countryside and therefore evaded the measures used to combat the epidemic, this was caused to a significant degree by the fact that many Jews had succeeded in breaking out of the quarantine zones in the cities. Very often the inhabitants of a community could give very exact information as to who had brought the disease. Not infrequently, however, it was the Polish farmer who brought a typhus infection upon himself when he, as was customary, without comprehending the precariousness of his acts, took a wandering Jew along on his vehicle for a ride for part of journey.

        As the month of May came to an end, the illnesses in the cities decreased markedly but the countryside was still very much affected. Numerically the high point had passed but the danger that farming communities would be dangerous endemic centers of contagion was not eliminated. Contrary to expectations and without any apparent reason, the number of affected persons declined suddenly in the second half of June in the countryside. Since for a long time already, about 20-25 small towns had been identified in which new cases were reported, the number suddenly fell back to 5 or 6. Shortly before there had been an increase in the summer temperatures and perhaps the increased formation of perspiration diminished the multiplication of lice and consequently the virus. This development was of course consistent with the usual decline for the disease during the summer months but the simultaneous decline over a wide area was striking, nevertheless, on the whole, the course of the epidemic was more or less typical because the late winter and early spring months had, just as during many other typhus outbreaks, brought the peak of the illnesses.

        The subsequent course of the epidemic for the rest of the year 1940 was typical also. The summer months showed only isolated cases and it was only the month of November which slowly brought once again the winter rise of the pestilence.

    Summary

    (1) The epidemiological circumstances of typhus in the Generalgouvernement in the year 1940 were examined thoroughly. (2) The results showed that the highest number of cases occurred within the age groups of 16-20, and that the percentage of Jews affected by typhus was on the average 70-80%, in some communities even 95-97%. (3) The mortality rate generally grew with increasing age. It was no less for Jews than for non-Jews.

    Sanitary Conditions and Contagious Disease Control in the Generalgouvernement

    (Gesundheitsverhaeltnisse und Seuchenbekaempfung im Generalgouvernement)

    by Dr. Joseph Ruppert, MD

    Chief Advisor for the Department of Hygiene for the Administration of the Generalgouvernement and Hitler Youth District Doctor, Cracow

    translated by F. P. Berg from:

    Der praktische Desinfektor (Berlin: Hygiene-Verlag Erich Deleiter, 1941),

    Heft 6, pp. 61-3 and Heft 7, pp. 72-5.

       


    The inadequate hygienic conditions which existed earlier within the present Generalgouvernement were always well-known throughout the world. One referred to them in colloquial jargon when one was speaking about uncleanliness or disorderliness. The expression "polnische Wirtschaft [Polish housekeeping or `a terrible mess'1]" and what it implied was understood by everyone.

        In the past, as long as I was still living in East Prussia, whenever I would occasionally make a weekend trip or travel for a weekend by car "into the Reich" and would pass through Polish territory, I would be immediately struck by the fact that I had left the German border behind me and that I was now confronted by what the expression "Polenwirtschaft" really meant: bad roads, rundown villages, practically all houses in a poor and primitive state, dirty people clad in rags, etc. On the approximately 130 km (80.8 miles) long road which I travelled from the Eastern border to the Western border of the Polish corridor, I would notice the oncoming automobiles. As I traveled on the Polish territory, I would count twice as many German vehicles as Polish. All of this, in addition to the inadequate road markings and the absence of traffic discipline of the population, already gave me after these few facts visible proof as to the backwardness of the Polish state and its cultural niveau. I believed at that time, even though I was only seeing the "outward facade (Kulissen)" of the Polish state, that I had nonetheless acquired a one hundred per cent accurate impression of the Polish state without even suspecting that what was actually hidden behind this facade would, for any half-civilized human being, be the most inconceivable, ultimate Dreckwirtschaft (filthy mess) of the highest virilence. I had no more inkling about all of this than I did about the now established fact that the hygienic-sanitary deficiencies of this country would ever become, for me personally, such a deeply burning professional problem. Nowadays, I must concern myself with these matters day in and day out,--and not only with these, but also with those behind the Polish facade. What is hidden there, is beyond one's wildest imagination. An attempt, to try to convey in words those things which one has actually seen, need not even be made. One must have seen for oneself in order to hold these pictures accurately within oneself and true to life. And what does one see! With one word--Dreck (filth), Dreck, and even more Dreck. On the wooden steps of the hallway I would see the dirt, more than once, as thick as on the mud-covered streets. Gloomy darkened apartments, in which one almost stops breathing upon entering, the toilets of the apartment in a disgusting condition, in the flat countryside often no toilets at all. Whoever knows these conditions is not surprised, if any further convincing is at all necessary, that even in hospitals they would encounter totally inadequate sanitary facilities which led me to comment once to the chief physician during a prearranged inspection: "If your hospital would be a prison, then I as a German would say--poor prisoners."

        And now, we come to the Jewish milieu which one encounters here in its totally undisguised (unverfaelscht) "prototypical form"! If one is inclined to believe that the "specimens (Kostproben)" which one sees in illustrated magazines are simply staged photographic montages, here they will be confronted everywhere in Jewish apartments by just how true those reproductions which have been published actually are to reality. Here one encounters conditions which are astounding--that human beings are at all capable of vegetating in such superb centers of contagion for vermin and filth-related sicknesses (Schmutzkrankheiten). In the houses one often finds a labyrinth of low vault-like passageways where once in awhile shabby, bearded bodies dressed in caftans pass by; or else, distinct criminal types of whom one can expect anything talk with a Yiddish accent (mauschelnd), hang around in corners so that one reaches instinctively for one's pistol to be sure it is ready to fire at any moment. One gropes around in the dark to find the apartment doors, behind which new scenes appear. In a half-darkened room in which, if one steps firmly on the floor, the dust swirls about in the penetrating light rays and where one will find as the only furniture: a dilapidated oven, a prehistoric (vorsintflutliche) dresser from which old rags are oozing, and a table with chairs to match the rest of the decorations. The room is "alive (belebt)" with a number of typical characters--hats tilted back to their necks--just like the ones I have already described. There, in word and tone, the original "Yiddish" is spoken just as we are accustomed to hear it spoken by our former Moses-descended livestock dealers and other Jewish merchants in the flat countryside and of whom we have had enough. "Mischpoke" in its purest form. The demeanor: grovelingly devoted, of a sweetly dripping and offensive friendliness which, knowing the Jew, can only arise from two motives--either the wish to conduct a "Geschaeftche (a small business transaction)" or to get a probably undeserved, merciful evaluation. This alone, but finally also the fear that it could cost them their heads, makes them so sheepish and restricts their relentless criminal inclination which is so thoroughly inscribed in their faces.

        Again and again, I have the silent wish that all those who are occasionally still plagued by some kind of displaced humanitarian impulse could accompany me. Here they will be guaranteed an instant cure!

        But by far, not everyone who comes to the East can see this. The visitor lives and moves about mostly only within the civilized portions of the city and goes, perhaps, once in awhile through the streets of the Jewish section. This will already give him sufficient impressions. But one must have been inside the "dwellings" in order to get the true picture.

        And so, how could it be otherwise, that Poland with its large Jewish population who had over the years become closely interrelated with the national Poles would ever since then be a pestilence-ridden area. Sicknesses which we hardly know anymore in the Reich, which old experienced doctors saw neither as students in the university clinics nor in their practices later on, or sicknesses which we only see sporadically are here so widespread and occur in such large numbers that one would not imagine it possible on the periphery of the European cultural center. With such "hygienic" conditions it is inevitable that infectious diseases will remain indestructible, permanent guests if one is unwilling to confront them with a thoroughness which is characteristic, thank goodness, only of Germans.

        In addition to the organizational buildup of the Health Department under the expert professional and often admirable, visionary guidance of the president of the Department of Health, the Obermedizinalrat and District Health Commissioner Dr. J. Walbaum, it was therefore decided from the very beginning to pay increased attention to the fight against the pestilence. After this short war had spent itself so quickly over the country with its inevitable accompanying phenomena there was, logically enough, an increased danger.

        As I have already mentioned, one glance at the statistics for infectious diseases for former years for Poland shows that the status of the pestilence was always extraordinarily high and far beyond the bounds of conditions to which we are accustomed in the Reich. To evaluate the status of the pestilence with the help of the still available statistical material in comparison to the current information, one can only use the numbers in a limited fashion since the area of the Generalgouvernement is not identical to that of the former Poland from where these numbers originate. Furthermore, we know that we cannot get an exact picture from these available numbers about the status of the pestilence in Poland since the statistical data was not at all thorough but was only an approximation and the numbers are too far removed from absolute values to be a practical basis for making decisions.

        What one should believe about Polish statistics was made clear by a highly placed Warsaw government medical official of the Polish period in some self-compromising remarks he made some years ago to a provincial doctor; literally translated: "There are three kinds of lies, the simple lie, the arrogant lie and in its highest form--the statistical lie." That was an authoritative Polish opinion and it says it all! We personally have also seen how hard it was to educate Polish doctors and administrative doctors--in many places only with pressure--to be punctual and orderly in reporting illnesses and fatalities as has been prescribed by law for years already.

        On the basis of these facts and on the guidelines established to fight contagious diseases, numerous ground-breaking measures were necessary, since we were protecting not only the Germans in the Generalgouvernement against infectious diseases so as to eliminate occurrences in the Reich with which there was a constant traffic flow, but there was also the danger which had to be eliminated that the disease would spread among the Polish population because of wartime conditions. At first there was a regulation that all German officials and civil servants from the Reich were to be inoculated against typhus in order to give them an immunobiological protection against the disease. The inoculations were given partly by sanitary officers and partly by German civilian doctors from the Reich. The protection lasts one year at most and has to be renewed after this period with a one-time inoculation. As to a thorough inoculation program for small-pox, it was not deemed necessary because the Polish population had for years been inoculated against small-pox so that one did not expect any cases of small pox. According to Polish law, children in their first and seventh years are inoculated against small pox; for that reason, measures were planned and implemented in the summer of 1941 to also inoculate those children of these ages against small pox. The inoculations are being given by Polish regional health doctors who were subsequently reassigned to serve as field doctors (Aussenbeamte) in the Polish provinces. To be sure that Reich and ethnic German children would be inoculated by German doctors, we passed a special regulation.

        To be successful against the danger of the pestilence, it was at first necessary to clearly understand the existing relevant Polish law, since Polish laws are adhered to in administering the Generalgouvernement. For health matters relating to infectious diseases the "Law to Fight Infectious Diseases" and the "Inoculation Law" are adhered to. Those two laws were translated and found acceptable since they are closely modelled on the German Reich laws and, consequently, were adopted without any change. Based on the existing laws which were also known to the Polish doctors, necessary methods were decreed to fight against infectious diseases.

        Step by step, all Polish hygienic-sanitary laws are being translated by an experienced former public health doctor and a judicially trained German public health doctor into appropriate form and distributed to all public health offices of the Generalgouvernement, so that every German doctor in the public health service can become thoroughly familiar with the Polish regulations. In this way, he will be able to carry out all his responsibilities as well as observe and supervise the practices of the Polish doctors so that the Polish laws which are based, in most cases, on German experience are generally quite acceptable but which have been heretofore neglected will be implemented with German thoroughness. In so far as there were dangerous loopholes within the Polish law, they were closed by additional regulations from the Generalgouverneur at the request of the President of the Department of Health Services. If one observes the current status of the pestilence, we should only briefly apply ourselves to the diseases which are at this time in the foreground or which are of special importance for the health of the population. As such there are especially typhus, typhoid, dysentery, rabies, trachoma and, finally also, venereal diseases.

        Typhus is a serious infectious disease which is not common in Germany and was only observed sporadically in peacetime when it was carried in from foreign countries. The death rate for typhus swings between 2.5 and 50 per cent of those infected by the disease. The sickness becomes far more dangerous with increasing age. The responsible micro-organism is the Rickettsia provazeki which is carried by a bacillus carrier, the clothes louse. The importance of typhus for Poland is obvious if one familiarizes oneself with the available statistics of past years. One clearly sees that Poland has always been the country of diseases, especially that of typhus. East and Central Poland were more affected than were the western provinces which border on Germany where there was almost no typhus at all.

        Especially vulnerable were the big cities which had primarily Jewish ghettoes with typical centers of contagion. Thorough inspections and orientation regarding the disease condition right there and then were necessary. One had to partially close off whole blocks and sections while always guaranteeing the food supply for the inhabitants. The diseased were immediately isolated, even special hospitals for infectious diseases were constructed, the relatives and co-tenants were deloused and quarantined, the hospital staff was given special training and, since most of the diseased were Jewish, a Jewish security police was established and given responsibility for the precise implementation of the rules under the supervision of a special unit (Sonderkommando) of the Polish police. To restrict the possible spread of the disease even further, one had to perform sufficient delousings and construct large numbers of delousing stations. Where such stations existed but in a totally inadequate fashion, they had to be expanded considerably. Since the Jew was practically the only carrier of the disease--even if the diseased were not Jewish, one could in most cases trace the disease contact to a Jewish source of infection--it did indeed seem to be urgently necessary in order to protect the populace to curtail the free movements of the Jewish inhabitants, to make the use of the railroads by the Jews dependent on a special official medical permit and then only in urgent cases, to designate special park areas for walks in the open (since, for instance, by shared usage of the park benches it was very easy to promote the transmission of lice), to forbid the use of busses for the same reasons whereas in trolley cars the Jews had to be given special compartments. The Jew represented an especially difficult problem within the struggle against diseases anyway. With his removal as the source of infection, the most important element of danger is already eliminated.

        It could well be, that the strict measures which we had to implement out of necessity will be seen by the Jewish or Jewish sympathetic side as an opportunity to exaggerate and manufacture atrocity propaganda which can then be spread throughout the world as we know all too well (in der bekannt beruechtigten zusaetzlichen Aufbauschung in die Welt hinausgehen.) But everyone who is familiar with local conditions, even if only slightly familiar, has a chance to convince himself of the absolute necessity of these protective measures.

        If there should be any doubt at all that the Jew is the carrier of the infectious diseases, we need only point to the fact that the proportion of the Jew is not a piece of disseminated anti-Jewish sham put out by the German side but that we are relying solely on those reports which are coming in from German public health offices by the Polish, and which are even supported in part by Jewish doctors. Because of the implemented measures, we were able in all cases to stop mainly typhus which is receding everywhere. The most recent reports of epidemic diseases show only a fraction of the numbers in comparison to the same month of the previous year.

        Typhoid has always played a major role in Poland and occurs even now relatively often among the population. There is no danger at all for the Germans because inoculations were given immediately. Furthermore, there were extensive control measures which were applied mostly to the hygiene of the water supply, the sewage system, the dairy processing plants and the Bacillus dischargers.

        In special bulletins the public health doctors were given thorough and detailed instructions in all the dangerous aspects and control measures, so that every doctor had a necessary weapon against the spread, and everyone in his place knows immediately at a point of increasing danger what he has to do in this case to successfully prevent and fight against the disease.

        Every Polish and German public health doctor has on hand an extensive service regulation, in which framework (scope??) the disease protection because of its increased importance for the Generalgouvernement has been given a special place.

        Already in the fall months of 1939 we German doctors saw that even cases of dysentery had increased several times. . . . It seemed to us therefore that after extensive consultations with experienced epidemiologists that it was not necessary to inoculate against this disease. To us Germans it is self-evident to know and practice hygiene everyday, therefore, we published memos to protect against dysentery and in ten rules we would identify the several dangerous sources.

    10 Commandments

    1. Cleanliness for you and your children is of utmost importance. Wash your hands before eating and after using the bathroom otherwise you can transfer the dysentery bacillus onto door handles, stairway railings, foodstuffs, etc.

    2. Flies carry the disease organisms from the feces of people infected with dysentery onto foodstuffs. Therefore, fight flies energetically and protect all products which are designated for human consumption against the arrival of flies.

    3. Wash all unpeeled raw food items before they are served several times in cold water and dunk them briefly even in hot water. Then you need not do without the nutritionally important fresh vegetable produce.

    4. Avoid unripened fruit and spoiled foodstuffs since they can give access to disease.

    5. Seek medical advice if in the summer or fall you are stricken by dysentery and pay the utmost attention to the doctor's instructions.

    6. Limit yourself to boiled food if dysentery is established in your area. Use only boiled water and avoid raw milk, ice cream, etc.

    7. Shop only in hygienically ideal shops and only go to those restaurants which vouch for absolute cleanliness.

    8. Seek only hermetically closed and clean bathrooms. Human wastes discharged in the open should be carefully covered with soil.

    9. Avoid everything which could lead to intestinal disease.

    10. Seek professional help and treatment immediately in a hospital if you are stricken with dysentery. You yourself will receive tbe best care and your surroundings will therefore be protected against infection.

        For us Germans it is almost unbelievable if one follows the statistics for rabies of the last years. In the Reich, this disease is most rare. . . .

        Even the Egyptian eye disease was found to be very prevalent in Poland. . . .

        Even venereal diseases always played a significant role in Poland. This fact is illustrated sufficiently by the existence of venereal disease in comparison to the existence in Germany on a proportion of 1:7, that the effects of this epidemic which ravages the life of the Polish people. . . .

        In order to control contagious disease, in addition to other facilities, the Federal Hygienic Institute in Warsaw with its three affiliated institutions was put under recognized German leadership. The institute also acquired a typhus research center which had in addition to the research on the epidemiology of typhus the production of serum to take necessary inoculations. That the control of contagious disease in the Generalgouvernement was closely linked with the Wehrmacht, with the Department of Veterinary Sciences and with all other interested offices for the control of disease is self-evident and needs no special mention. To complete this, one should briefly describe other organizational methods: establishment of disease departments, addition to the reporting systems, implementation of registration forms and disease report forms, organization of the transport of the sick, distribution of instructions to the Polish doctors, preparation of inoculation records [?], acquisition of vaccine, regulation of the medical care of the population, implementation of delousings. The overall situation as far as the danger of contagious diseases in the Generalgouvernement is concerned is already more ideal than it ever was at the time of an independent Poland, a result which within the short time of the German administration of the Generalgouvernement under the consideration of the war status, the connected environmental conditions, the total lack of sanitary measures and the unhygienic lifestyle of the populace seems hardly believable.

        When we took over [in Poland] there were practically no useful files with which to build an organizational structure; it had to be built out of practically nothing at all. All of the files from which we might have gained something were destroyed. If we were nonetheless successful in creating the necessary conditions for public health, then this is not only because of the organizational talent of the Germans but also because of the painstaking conferences, negotiations and the careful research into existing measures which could be applied again . . . .
