First imported cases of MPXV Clade Ib from Goma, Democratic Republic of the Congo

Nature The ongoing mpox outbreaks in the Democratic Republic of the Congo (DRC) resulted in >71,000 suspected cases from 01 January 2024 to 02 February 2025. Clade Ib mpox virus (MPXV) emergence has heightened public health concern due to observed sustained human-human transmission and spread to multiple non-endemic East African countries. Clade Ib outbreaks have been marked by epidemiologic deviations from classic Clade Ia zoonotic transmission—Clade Ib instead has been observed among adult populations and transmission via sexual contact. With the continued expansion of Clade Ib across the region, containment and mitigation measures may need to be adapted to best fit this novel MPXV clade.
