[Arbovirus infections on the island of Nosy-Be; serologic and entomologic findings].

Since 1977, the Pasteur Institute of madagascar has been studying, during six surveys, the arboviruses of Nosy-Be area, in the north-west of Madagascar. 47.2 p. 100 out of 271 human sera and 11.3 p. 100 out of 150 animal sera (mostly from Lemurs), tested for antibodies to 16 arboviruses by the haemagglutination inhibition test, are positive. The results show an important prevalence of Flaviviruses. West-Nile and Dengue 1 viruses were probably circulating some years before the surveys. Antibodies against Sindbis and Rift Valley Fever viruses, were found only in few subjects. Bunyamwera and Tahyna viruses are absent. The rate of positive Lemurs is weak, particularly in Lemur macaco species. Flaviviruses are the most frequent. 12262 haematophagous diptera (11965 Culicidae belonging to 40 species) were caught . Aedes aegypti and Aedes albopictus are both present. Arbovirus isolation attempts from 394 mosquito pools failed; only Mengo virus was isolated from four pools of Erethmapodites quinquevittatus and one pool of Aedes (Skusea) sp.

[Hemorrhagic fever viruses in Madagascar].

The authors remind, what are the viral haemorrhagic fevers, and explain the situation in Madagascar. The viruses of Crimée-Congo haemorrhagic fever, Rift valley fever and haemorrhagic fever with renal syndrome are present in Madagascar. There is no real proof about the presence of Dengue viruses. The yellow fever viruses have never been stown off. It seems that there was not diagnosed outbreak of haemorrhagic fever, since the beginning of our century.

[Cyto-microbiologic study of cervico-vaginal specimens, associated with a serologic study to detect sexually transmissible diseases in Madagascan prostitutes].

A microbiological survey of cervical and vaginal smears associated with a serological survey of sexual diseases was carried out on 298 prostitutes at the four principal Malagasy sea ports. This survey leads us to these conclusions: The great frequency of specific inflammations (72.1%) with Trichomonas vaginalis in the first place (39.2%). The serological tests proved a high rate of positive treponemical serologies (25.2%), whose the half of the cases are evolutive forms. Nevertheless prevalence of HBs-antigene among this population does not exceed the rate recorded in the other African countries, while the rate of anti HIV antibodies' carriers is lower than the rates recorded in those African countries. A comparative survey with tests carried out at IPM on Malagasy women showed clearly higher figures of inflammations, cervical and vaginal infections and positive treponemical serologies among prostitutes.
