[Recommendations for travel and residence in the tropics (author's transl)].

Increased tourism into tropical countries and the use of German labor forces in such countries make it necessary for doctors to advise emigrants properly. Besides vaccinations and drug prophylaxis, a rational way of life is extraordinarily important in the tropics, skin care, cleanliness, hygienic living, suitable clothing and sports activity are important factors to which attention must be paid. Additional salt is necessary if sweating is profuse. Alcohol should not be drunk before sundown. Examination before setting out for the tropics and after return for lesions and infections which may have appeared during residence in the tropics are urgently recommended.
