Lake Chad basin - Cross-border Meeting - Niamey, 2014

Background :

Situation of the cholera outbreak in the Lake Chad Basin area (Week 13, 2014)
As of 30th of March 2014 (S13), 12,531 cases of cholera and 179 deaths (case fatality ratio: 1%) were reported in 14 States and 68 LGAs in Nigeria. On Week 13, the State of Bauchi reported 9,146 cases of cholera, about 75% of all cases reported on a national level since the beginning of the year. 90% of all cases are reported in urban areas. A cholera outbreak is currently reported in the Touboro district (cf. Figure 2), in North Cameroon, at the border with Chad and CAR. Between the 19th and the 28th of March 2014, 9 cases of cholera, including 4 deaths, were reported. Additional in-depth investigation are required to determine how the pathogen was introduced in the North region of Cameroon. Touboro market receives goods originating from Nigeria, namely from the State of Bauchi.

Note that a set of conditions are met highlighting a possible move towards a "complex" outbreak in the Lake Chad Basin area:


High-risk cross-border areas
An integrated "Water, Hygiene, Sanitation and Epidemiology" study conducted in 2011 in the Lake Chad Basin area identified the high-risk cross-border spreading areas where vulnerability to cholera outbreaks is high (Figure 2) (Annex 1). The study highlights the importance to improve cross-border surveillance, preparedness and collaboration on a national level and at the periphery between Chad,Cameroon, Niger and Nigeria.
