OVERVIEW OF CHOLERA

Cholera was first reported in Guinea in 1970. Since 1990, there have been large outbreaks in 1994, 1995, 2007 and 2012 (Fig. 1). Between 2003 and 2013, epidemiological surveillance reported 25,358 cases with 952 fatalities (high case fatality rate ≈ 3.8%)1. The main outbreaks were reported in coastal regions: Conakry, Kindia and Boké (Fig. 2 and Tab. I). Coastal outbreaks are mainly associated with cases in Sierra Leone or Guinea Bissau (between February and June). Then, outbreaks extend to Conakry and its suburbs between June and November, coinciding with the rainy season6.

APERÇU DU CHOLÉRA
Le choléra est apparu pour la première fois en Guinée en 1970. Depuis 1990, des épidémies importantes ont été enregistrées notamment en 1994, 1995, 2007 et 2012 (Fig. 1). Entre 2003 et 2013, 25 358 cas et 952 décès ont été enregistrés avec un taux de létalité élevé de 3.8 %1. Les épidémies majeures ont été enregistrées dans les régions côtières à Boké, Kindia et dans la capitale Conakry (Fig. 2 et Tab. I). Les épidémies côtières sont reliées en général à des cas notifiés dans les préfectures côtières de la Sierra Leone ou de la Guinée Bissau (entre février et juin). Dans un second temps, l’extension de l’épidémie a lieu à Conakry et sa périphérie entre juin et novembre, coïncidant avec la saison des pluies6.

STRATEGIC RECOMMENDATIONS

Preparedness activities, sustainable Water, Sanitation and Hygiene interven­tions and vaccination campaigns with oral cholera vaccine (OCV) should be conducted primarily in prefectures regularly affected with long duration out­breaks (Tab. II, Type 1). Establishing a cross-border early warning system in the coastal districts along the Gulf of Guinea from Ghana to Guinea-Bissau through the surveillance of migrant fishermen’s movements is essential6,7. In 2012, a response strategy was developed in the urban area of Conakry based in part on georeferencing patient home6. This method helps stream­line the resources necessary for the response and guide interventions in clusters of cases. A 2012 integrated WASH-Epidemiological study in the prefecture of Forécariah identified a dozen fishing villages on the coast where the high density, high mixing and low access to safe drinking water and sanitation undeniably favoured the transmission of cholera6. The study proposes the development of Local Plans for Elimination of Cholera and the following intervention areas: 1) Institutional, 2) Administrative, 3) Communi­ty, 4) Infrastructural, 5) Commercial and 6) Behavioral. In 2012 and 2014, reactive and preemptive targeted vaccination campaigns were conducted along the coastline (Boke, Boffa, Coyah, Dubréka and Forécariah)8.
