[Evaluation of immunological and entomotological indices of yellow fever in Pointe-Noire, People's Republic of Congo].

The authors report the results of a serological sample survey managed to evaluate the prevalence of two types of yellow fever antibodies, connected with an entomological survey, in the town of Pointe-Noire in the People's Republic of Congo. According to the high rate of non protected people, the high level of entomological indices and the characteristics of local environment, this densely populated town may be considered as an area exposed to a potential hazard of a yellow fever outbreak. A vaccinal strategy ought to be planned according to this situation.
