Epidemiological survey of malaria in kinshasa zaire in 1980

A survey was carried out in the city of Kinshasa by means of spleen rate, parasite rate and serology using the indirect fluorescent antibody test. An overall parasite rate of 33% was observed among the 2267 children from 0-15 yr examined during the survey. The great predominance of Plasmodium falciparum is a normal feature in Central Africa. Seasonal variation is not marked, characterizing stable malaria. Sharp differences in prevalence observed between different areas in the city are probably the result of different socioeconomic levels, of the presence or the absence of permanent water collections and of the accessibility of the area. Transmission is, thus, a local phenomenon. Parasite index does not decrease after the age of 9 and the percentage of antibody carriers increases very slowly in the 10-15 yr group. These 2 features prove a delayed acquired protective immunity. The serological index (percentage of antibody cariers) is always higher than the parasite index, and the latter is, in nearly every case, higher than the spleen index.
