Africa's cholera crisis worse than ever

blog

Lilanda, Zambia, May 25: Extreme weather events have hit parts of Africa relentlessly in the last three years, with tropical storms, floods and drought causing crises of hunger and displacement. They leave another deadly threat behind them: some of the continent's worst outbreaks of cholera.

In southern and East Africa, more than 6,000 people have died and nearly 350,000 cases have been reported since a series of cholera outbreaks began in late 2021. Malawi and Zambia have had their worst outbreaks on record. Zimbabwe has had multiple waves. Mozambique, Kenya, Ethiopia and Somalia also have been badly affected.

All have experienced floods or drought — in some cases, both — and health authorities, scientists and aid agencies say the unprecedented surge of the water-borne bacterial infection in Africa is the newest example of how extreme weather is playing a role in driving disease outbreaks.

“The outbreaks are getting much larger because the extreme climate events are getting much more common," said Tulio de Oliveira, a South Africa-based scientist who studies diseases in the developing world.

De Oliveira, who led a team that identified new coronavirus variants during the COVID-19 pandemic, said southern Africa's latest outbreaks can be traced to the cyclones and floods that hit Malawi in late 2021 and early 2022, carrying the cholera bacteria to areas it doesn't normally reach.

Zimbabwe and Zambia have seen cases rise as they wrestle with severe droughts and people rely on less safe sources of water in their desperation like boreholes, shallow wells and rivers, which can all be contaminated. Days after the deadly flooding in Kenya and other parts of East Africa this month, cholera cases appeared. (AP)
