[Malaria transmission in an area of future vaccination in equatorial forest of south Cameroon].
In order to describe malaria transmission in a future antigamete vaccine trial area, a longitudinal entomological study was conducted, together with parasitological and immunological surveys, from June 1997 to May 1998 in two nearby villages in a tropical rain forest area 100 km east of Yaoundé. Koundou is located along the main road in an open and degraded environment combining cultivated lands and forests; Ebolakounou is located 5 km from the road in forest surroundings. Indoor mosquito night catches no human volunteers were performed twice a month, in ten houses. We determined the entomological infection rate as 176 infected bites per human per year in Koundou (47.7% for An. moucheti, 47.3% for An. gambiae and 5% for An. funestus) and only 17.7 infected bites/human/year in Ebolakounou, with An. gambiae only. Transmission appears to be ten times higher in the village situated in a degraded environment than in the village situated in the rainforest.
