Cholera Background History:
Cote d'Ivoire
Cholera cases started to be reported in Côte d'Ivoire when the 7th pandemic hit the African continent with respectively 868 and 668 cases reported in 1970 and 1971.
From 1991 until 1996, Côte d'Ivoire reported cases each year ranging from 37 to 4'993. From October 2000 to October 2001, the largest outbreak unfolded affecting 21 districts with 6'260 cases (incl. 341 deaths) being reported. The overall case fatality rate was 5.44%. Abidjan recorded 3250 cases (51.9% of all reported cases) and the case fatality rate remained lower in the capital than in other affected regions. In previous years, Abidjan had reported sporadic cholera cases during the rainy season. An outbreak of this scale that was to last all year and extending beyond the rainy season was a new situation. Cases were also reported in the neighboring countries of Burkina Faso and Guinea.

From 2001 until 2005, 11'874 cases including 564 deaths were notified with an overall CFR of 4.7%. Abidjan recorded 60% of the cases with a lower CFR of 2.1%.
Other outbreaks occurred in the transit districts or displaced camps occupied by the displaced persons from the northern regions. The armed conflict in 2002 highly disturbed the surveillance system.
From 2004 until 2008,Côte d'Ivoire notified sporadic cases from several regions.

Cholera Outbreak in 2011:
Cholera cases have been reported in Abidjan since 19 January 2011. Cases were first reported in Adjamé and then further spread to two nearby communities: Atékoubé and Yopougon (see map).

As of 6 March 2011, the Ministry of Health has reported a cumulative number of 531 cholera cases including 12 deaths (CFR = 2.3%). A total of 12 districts are affected of which 5 are in Abidjan (see map). Of the reported cases, 29 are laboratory confirmed. The CFR reduced from 12% at the onset of the outbreak to 2.3% by week 9.

The surveillance system is challenged due to the volatile security situation and information on the epidemic trend is not rapidly available.
