Two outbreaks of mpox in sub-Saharan Africa are raising concerns about the continued spread of the virus globally —- and the surge of a deadlier strain than the one that began circling the globe in 2022.

Another concern is the Democratic Republic of Congo, where an outbreak that began last year has been accelerating – and where the variant is dramatically deadlier than the mpox strain of 2022.

In 2023, DRC reported 14,434 suspected cases and 728 deaths. The pace seems to be increasing this year, with more than 11,000 cases and 445 deaths already reported in 2024, according to the World Health Organization.
