This study will estimate the cumulative incidence of Zika infection at the end of the first epidemic in the French West Indies in a sample of patients followed for HIV infection.
Zika virus infection is expanding in all tropical and subtropical areas. The presence of Aedes albopictus in southern France raises concerns about the occurrence of outbreaks of indigenous Zika virus transmission. In this context, knowledge of the cumulative impact of the epidemic that affected the Caribbean in 2016 is an important issue for the management of future epidemics and modeling work. Since the Zika virus has not yet been circulated in the Lesser Antilles, the cumulative incidence rate can be estimated by conducting a general population seroprevalence survey at the end of the epidemic, or more simply within a cohort of patients regularly monitored and whose habitat is distributed throughout the study area. Thus, HIV-infected patients who benefit from regular clinical biological monitoring constitute a population sample perfectly adapted to the study of the emergence of the Zika virus in the French West Indies. The cumulative incidence of infection with the chikungunya virus after the 2014 epidemic has thus been estimated at 58% for Martinique and Guadeloupe using this method.
