National Surveillance Data on the Epidemiology of Cholera in Cameroon

National Surveillance Data on the Epidemiology of Cholera in Cameroon Background.The cholera burden in Cameroon has increased during the past 2 decades.

Abstract

Background.The cholera burden in Cameroon has increased during the past 2 decades. During 2010 and 2011, the largest number of cholera cases in Cameroon since February 1971 were reported. This article describes cholera outbreaks during 20102011.Methods.Data received from the national surveillance system from 2010 and 2011 were compiled and analyzed.Results.The first suspected cholera cases were reported in the Far North region on 6 May 2010. In 2010, 10 759 cholera cases were reported by 8 of the 10 regions in the country, with 657 deaths (case-fatality ratio [CFR], 6.1). In 2011, through September 22, 17 121 suspected cholera cases, including 636 deaths (CFR, 3.7), were reported all over the country. During 2010, the Far North region accounted for 87.6 of cases (9421/10 759) and 91.6 of deaths (602/657) recorded. By contrast, during 2011, 5 regions (Far North, North, Center, Southwest, and Littoral) accounted for 90.6 of cases (15 511/17 121) and 84.0 of deaths recorded. Vibrio cholerae was identified in 525 stool specimens, and all organisms were serogroup O1.Conclusions.The ongoing cholera outbreak in Cameroon increased in intensity and geographic spread from 2010 to 2011. Nevertheless, the overall CFR decreased during this period. Strengthening the early warning system and enhancing water, sanitation, and hygiene interventions and sensitization should be considered in addressing cholera outbreaks.
