Abstract

ObjectiveTo report on the results of three size estimations of the populations of female sex workers (FSW) in five cities in Cote d'Ivoire and on operational lessons learned, which may be relevant for key population programmes in other parts of the world.

MethodsWe applied three methods: mapping and census, capture-recapture and service multiplier. All were applied between 2008 and 2009 in Abidjan, San Pedro, Bouake, Yamoussoukro and Abengourou.

ResultsAbidjan was the city with the highest number of FSW by far, with estimations between 7880 (census) and 13 714 (service multiplier). The estimations in San Pedro, Bouake and Yamoussoukro were very similar, with figures ranging from 1160 (Yamoussoukro, census) to 1916 (San Pedro, capture-recapture). Important operational lessons were learned, including strategies for mapping, the importance of involving peer sex workers for implementing the capture-recapture and the identification of the right question for the multiplier method.

ConclusionsSuccessful application of three methods to estimate the population size of FSW in five cities in Cote d'Ivoire enabled us to make recommendations for size estimations of key population in low-income countries.
