[Update on a neglected tropical disease from the routine health information system in Côte d'Ivoire: Yaws, 2001 to 2011].

GOAL: The aim of this work is to describe the epidemiological characteristics of yaws in Côte d'Ivoire from 2001 to 2011, by data from the routine health information system.

METHODS: This retrospective study was conducted from available health statistics from 2001 to 2011.

RESULTS: From 2001 to 2006, the completeness of the regional health statistics was below 50%, while afterwards it exceeded 70% in all regions. The incidence rate of yaws in hospitals has declined from 44 to 14.8 per 100 000 population from 2002 to 2011. Two regional offices still reported highly endemic areas rates, four times higher than the national incidence.

CONCLUSION: It appears that the action of donors has helped to improve the performance of the routine health information system in Côte d'Ivoire. Additionally, yaws remains endemic. The reduced incidence in hospitals is probably due to the reduction in their use by the population; the real population incidence is undoubtedly higher. A seroprevalence survey would make it possible to focus more accurately the upcoming mass treatment campaigns, under the aegis of WHO, to eradicate yaws.
