Weekly Regional Cholera Bulletin: 4 March 2024
The cholera outbreak in the WHO African Region has affected 18 countries over the last two years. Five countries are categorized as being in acute crisis (Democratic Republic of the Congo, Ethiopia, Mozambique, Zambia, and Zimbabwe), though there has been sustained decrease in weekly case incidence in Zambia and Zimbabwe. The southern region of the continent, now in the rainy season, is experiencing resurging outbreaks. The increase in rainfall levels is causing floods and landslides in communities. This raises the risk of outbreaks in countries that have not reported new confirmed cases. The seasonality of cholera outbreaks is an issue for countries to consider. They need to improve preparedness and readiness, heighten surveillance, and scale up preventive and control measures in communities and around border crossings. This will prevent outbreaks, engender early response and reduce cross-border transmission.
