    Abstract:
    In different countries opinions differ as to which chemotherapeutic methods should be used for malaria prophylaxis. It has long been the opinion of the Nordic countries, that WHO should give an official recommendation and the result is reflected now in the publication "Vaccination certificate requirements and health advice for internation travel." The malaria-endemic regions of the world are divided into 3 categories: regions without risk and no need for prophylaxis, low risk regions (A) with predominantly vivax inflections, risk regions (B) with predominantly chloroquine sensitive P. falciparum, and high risk regions (C) with often both chloroquine as well as sulfa/pyrimethamine resistance. Chloroquine is a sufficient prophylaxis for A-regions. For B-regions proguanil should be added and for C-regions only mefloquine is given. Proguanil was reintroduced basically because of Swedish research results in Liberia. An American initiative recommends for all regions, A-C, chemorprophylaxis as an alternative. However, a precondition is an observant traveller and clear instructions for self-treatment. Travellers who fall ill in a B-region should choose between Fansidar, mefloquine and quinine for self-treatment. Mefloquine has the least serious side effects, whereas quinine is therapeutically more safe. Fansidar very seldom gives any side effects. For C-regions only mefloquine is recommended for self-treatment. Nordic colleagues have recommended to double prophylaxis (chloroquine + Paludrine) treatment for the entire African tropical region. For short-time travellers to Kenya, Tanzania and Uganda, 6 tablets Lariam should be added. Only chloroquine is recommended for India and the Amazon region of South America. No chemoprophylaxis can guarantee full protection. Insect protection is therefore more important than ever. Malaria decreases the unspecific immune defense system. Surprisingly, repeated tests have shown that the AIDS frequency is not higher in patients with chronic malaria than for persons without plasmodia in the blood. In WHO's new little yellow booklet, a page concerning prophylaxis against AIDS appears. Equipment that is not new should be steamed or cooked for a least 20 minutes or treated with chemical disinfectants for at least 30 minutes. These measures should be enough to prevent HIV-infection.
