[Microbiological and parasitic risks associated with the stay in hot countries (author's transl)]
Abstract:
The microbiological and parasitic risks associated with the tremendous increase in the tourist traffic from West Germany and Austria into warmer countries are considerable even in the case of shorter stays, as has been confirmed by observations made on those returning from such areas. The most important groups of diseases -- worm diseases, amoebiasis, and malaria -- have maintained this ranking in Central and South America; in Africa, especially in the east, the incidence of malaria tropica is increasing. The proportions for Austria show that even numerically there are no great differences compared with West Germany. It seems that, as far as malaria is concerned, efficient prophylactic measures and reliable information are absent; at any rate, the cases of malaria tropica were severe and in the main no prophylactic measures had been taken. With the exception of Japan, the risk of hepatitis in all warmer countries and in the East in general is many times higher than in the Federal Republic of Germany and the length of stay is partly a determining factor. For instance, the risk of hepatitis is roughly forty times higher in India. All figures shown in this survey are supported by tables, literature, and personal experience.
Insights
International travel poses significant microbiological and parasitic risks, including worm diseases, amoebiasis, and malaria. Travelers often neglect crucial prophylactic measures, leading to severe infections and increased disease incidence in warmer destinations.
Area of Science:
- Travel Medicine
- Infectious Diseases
- Public Health
Background:
- Increased international tourism from Germany and Austria to warmer climates presents considerable health risks.
- Observations of returning travelers confirm significant exposure to microbiological and parasitic pathogens.
Purpose of the Study:
- To assess the microbiological and parasitic risks associated with international travel.
- To identify prevalent diseases and evaluate the effectiveness of prophylactic measures among travelers.
Main Methods:
- Analysis of disease incidence in travelers returning from warmer countries.
- Comparison of disease patterns between West Germany and Austria.
- Review of prophylactic measures and traveler information regarding malaria and hepatitis.
Main Results:
- Worm diseases, amoebiasis, and malaria remain the most significant risks in Central/South America and Africa.
- Malaria tropica incidence is rising in Eastern Africa, with severe cases often linked to a lack of prophylaxis.
- Hepatitis risk is substantially higher in warmer countries and the East, with duration of stay being a key factor (e.g., 40x higher in India).
Conclusions:
- International travel necessitates greater awareness of infectious disease risks.
- There is a critical need for improved malaria prophylaxis and traveler education.
- Hepatitis prevention strategies must be enhanced for travelers to high-risk regions.
