DR Congo Ebola cases top 10,000 as regional transmission concerns mount

The Democratic Republic of Congo has recorded more than 10,000 cases of Ebola during its current outbreak, according to official government health data, deepening international concerns that the virus could spread further across the continent.

A situation report issued by Congo's national public health institute confirmed 10,060 infections and 4,887 deaths since the crisis began in mid-May. The outbreak is driven by the Bundibugyo species of Ebola, a rare strain for which no licensed vaccine currently exists.

The ongoing crisis has surpassed the nation's 2018 to 2020 epidemic to become the deadliest and most widespread Ebola outbreak ever recorded in Congo. Across global history, it now ranks as the second-largest and second-deadliest, trailing only the West African outbreak between 2014 and 2016 that caused more than 11,000 deaths across Guinea, Liberia, and Sierra Leone.

In response to the absence of preventative treatments, a Phase 2/3 clinical trial named Tumaini—meaning hope in Swahili—has been initiated in Bunia, within Congo's Ituri province. The trial, backed by the Coalition for Epidemic Preparedness Innovations, seeks to evaluate an experimental vaccine against the Bundibugyo strain.

Cross-border transmissions have heightened regional vigilance. Kenya identified its initial infection earlier in October after a traveler arriving from Congo through Uganda died in Nairobi, leading to a total of nine confirmed cases in the country.

Nigeria also recently became the fourth African nation affected during the current wave. Medical authorities there have been investigating the transmission route of an infected patient, identified as the spouse of a Swiss diplomat, who had not visited Congo. According to Swiss officials, the woman likely contracted the virus in Uganda before she and her husband were medically evacuated to Switzerland on Monday.

Uganda previously recorded 20 cases across May and June, primarily linked to travel from Congo, but was declared free of the virus by the World Health Organization in August. While Ugandan authorities maintain that no active infections are present within their borders, the nation's health minister announced on Sunday that returning citizens who have traveled to Congo must complete a mandatory 21-day quarantine.
