Ebola Outbreak: 9,500 Infected as Nigeria Reports Fourth Nation

More than 9,500 people have been infected by the Bundibugyo virus since mid-May, and nearly half of those patients have died. This makes it the largest and deadliest Ebola outbreak in the history of the Democratic Republic of Congo. It is also the second largest globally, trailing only the 2014-16 west Africa epidemic which infected over 28,600 individuals. The outbreak has now spread to a fourth African country, Nigeria, marking the first case there in over a decade.

The Swiss foreign ministry identified the Nigerian patient on Friday as the Ugandan-born wife of a Swiss diplomat stationed in Abuja. Ministry officials stated she had not visited the Democratic Republic of Congo, where the virus was first detected. They believe she contracted the illness while traveling in Uganda with her husband. This account conflicts with earlier reports from Uganda, which claimed the woman had traveled to the eastern part of the Democratic Republic of Congo.

The discrepancy has intensified scrutiny over how the virus moved across borders. A Ugandan government spokesperson told Reuters on Thursday that Uganda currently has no active Ebola cases. The country declared itself Ebola-free in August after reporting cases in May and June. The World Health Organization continues to investigate the likely source of the Nigerian infection. Catherine Smallwood, a WHO Ebola incident manager in the Democratic Republic of Congo, said via video link from Geneva that WHO staff had no information indicating the patient traveled to that country.

The Africa Centres for Disease Control and Prevention is examining whether the patient had contact with an Ebola case in Kenya. Dr. Wessam Mankoula, the organization's head of emergency preparedness, noted that both individuals passed through Uganda's Entebbe airport on 3 October. Smallwood said a link to the Kenyan case is possible but requires comparing the timing of airport exposure with the onset of symptoms in Nigeria to determine the likelihood of infection there.

Experts remain cautious about this theory. Marion Koopmans, a Dutch virologist on the WHO Ebola emergency committee, described the airport link as very speculative without evidence of shared space. She noted that random presence at a large airport is not a supported epidemiological link under current standards. Nigeria's Health Minister Muhammad Ali Pate stated the case remains contained and that contact tracing is ongoing. He said the goal is to prevent the virus from moving into local communities.

The Bundibugyo virus is rare and lacks an approved treatment or vaccine. Melaku Yirga, vice-president for Africa at Prosper Global, emphasized that confirmed cases in Kenya and Nigeria require close cross-border cooperation. He stressed the need for rapid information sharing and resources for frontline health workers to respond quickly to emerging threats.
