Niger Cholera Factsheet


Cholera was first reported in Niger in 1971. Since 1990, there have been large outbreaks in 1991, 1996, 2004 and 2010–2012. The overall yearly trend shows an increase of frequency and size of outbreaks over time (Fig. 1). Between 1994 and 2013, epidemiological surveillance reported 21,538 cases with 978 fatalities (high case fatality rate ≈ 4.5%)1. Main outbreaks were reported in the region of Tillaberi along the Niger River and in the regions of Tahoua, Maradi and Zinder at the border with Nigeria (Tab. I). The country is affected by cross-border outbreaks, especially along its borders with Nigeria and Chad.

Le choléra est apparu pour la première fois au Niger en 1971. Depuis 1990, des épidémies importantes ont été enregistrées notamment en 1991, 1996, 2004 et 2010 - 2012. La tendance générale montre une augmentation annuelle de la fréquence et de la taille des épidémies (Fig. 1). Entre 1994 et 2013, la surveillance épidémiologique a rapporté 21 538 cas avec 978 décès, soit un taux de létalité élevé de 4,5 %1. Les principales épidémies ont été enregistrées dans la région de Tillabéri, le long du fleuve Niger, et dans les régions de Tahoua, Maradi et Zinder à la frontière avec le Nigeria (Tab. I).

High risk cholera areas along the border with Nigeria and the Niger River are located on a corridor where outbreaks spread from and to neighbouring countries — Mali, Benin, Burkina Faso, Nigeria and Chad — highlighting the importance of cross-border activities5 (Fig. 2, Tab. II). In districts regularly affected, preparedness and re­sponse plans should be developed and implemented including: (1) strengthening early detection and rapid response systems of which community based sur­veillance and cross-border alert; (2) setting up coordi­nation mechanisms across the sectors and borders; (3) building capacity on outbreak management; (4) targeted pre-positioning of supplies and (5) preparing communications messages and plans (Tab. II). Sustainable Water, Sanitation and Hygiene activities should be a priority in districts regularly affected and with a high duration (Tab. II, Type 1). There is a need for multidisciplinary studies to identify long-term programmatic responses in Type I and Type II Hotspots (Tab. II).
