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 Organization (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. In Zimbabwe, human cases have been reported every year since 2019, underscoring the need for stronger preventive actions.

 

“To end these outbreaks we must break the cycle of infection by first preventing the disease in animals. We are supporting the ongoing national outbreak control efforts by providing expertise as well as reinforcing collaboration with partner agencies for a common approach to safeguard human and animal health,” said Dr Matshidiso Moeti, WHO Regional Director for Africa.

 

Due to the scale of the outbreak in Zambia, shared ecosystem with neighbouring countries and frequent cross-border animal and human movement, there is heightened risk of regional spread of the disease. Control measures are being intensified. The national authorities have vaccinated more than 122 000 cattle, sheep and goats with support from FAO. Additionally more than 400 000 vaccine doses have been earmarked for 11 high-risk districts in the country’s Western province.
