An epidemic of yellow fever raged during the last three months of 1983 in South East of Upper Volta. It spread on about ten thousand square kilometers, in a bushy savanna area, affecting only populations living in contact with forest galleries, belonging especially to the peul ethnical group. The transmission of the virus was effected by sylvatic vectors, essentially Aedes furcifer. ⋯ The epidemic quickly decreased in the sylvatic area, owing to climatic conditions. A mass campaign of vaccinations prevented it from spreading to near urban centres. On this particular case, the thermostability on field of the vaccine 17D provided by the Institute Pasteur of Dakar was proved to be effective.

The authors report some failures of chemoprophylaxis and curative treatment of Plasmodium falciparum and Plasmodium vivax malaria. These infections were contracted in the area of the cambodian-thaï border by 8 Europeans treated by various regimens and 34 Cambodians treated by quinine. ⋯ Morphological particularities (abnormal pigment, lack of Schüffner dots) were noticed in these Primaquine resistant vivax strains. A possible relation is considered between Primaquine resistance and these morphological particularities.
