title: [Prevalence of malaria in Dakar, Senegal. Results of serological survey of pregnant and non-pregnant women].
abstract: The study of malarial seroprevalence in Dakar has interested 598 women among whom 377 pregnant and 221 non pregnant, between 15 to 45 years old and happens during the dry season, period of which malaria transmission is practically stopped in the locality. Among the tested serums by indirect immunofluorescence with Plasmodium falciparum asexual blood forms as antigen, 24.4% contained antimalarial antibodies. The serological index does'nt vary significantly according to the months during the dry season, the women age and their previous pregnancy number. On the contrary, the women who live in Dakar since less than 2 years, have e higher seropositivity rate of 33.7% than those who are there since more than 2 years, 20.0%. It is likewise for the women practicing chemoprophylaxy with chloroquine of whom 16.5% have antibodies against 26.0% among those who don't practice it. The seropositivity rate doesn't vary significantly according as the women are pregnant (24.7% of positive) or not pregnant (24.0% of positive). The weakness of the serological rate in the examined women, can be explained by the situation of Dakar in a weak malarial hypoendemic area. II shows that the major examined subjects have lost or have never had contact with Plasmodium what predispose them to make severe and complicated malarial attacks.
