Brazzaville. – Five countries in East and southern Africa are experiencing anthrax outbreaks, with more than 1100 suspected cases and 20 related deaths reported since the start of the year.

A total of 1166 suspected and 37 confirmed cases have been recorded in Kenya, Malawi, Uganda, Zambia and Zimbabwe – where the disease is endemic, with seasonal outbreaks every year – according to data reported to World Health Organisation (WHO).

Of the five countries, Zambia is witnessing its largest outbreak since 2011, with nine of its 10 provinces affected. As of 20 November, Zambia had reported 684 suspected, 25 confirmed cases and four deaths.

Only sporadic cases have previously been reported in animals and humans in the country. 

The outbreaks are presenting varied patterns in the affected countries.

In Kenya, three deaths have been reported this year compared with zero fatalities from over 200 suspected cases in 2022.

While the disease is endemic in animals in Malawi, the country reported its first ever human case this year.

Human anthrax cases have been reported in three districts in Uganda, with 13 deaths compared with two deaths in 2022.

The high case fatality ratio is due to patients reporting late to health facilities. – World Health Organisation
