9,500 Ebola Cases: Nigeria Confirms First Infection Since 2014

Nigeria has confirmed its first Ebola case since 2014, a development that marks the arrival of the Bundibugyo virus in a fourth African nation. The patient is the Ugandan-born wife of a Swiss diplomat stationed in Abuja. Health officials across the continent are now working to determine how she contracted the virus, a question that has generated conflicting accounts from government ministries in three countries.

The primary dispute centers on the patient's travel history. The Swiss foreign ministry stated on Friday that the woman had not visited the Democratic Republic of Congo, where the outbreak began in mid-May. According to Bern, she likely contracted the illness while traveling with her husband in Uganda. This account contradicts earlier claims from Ugandan authorities, who previously reported that the woman had traveled to eastern DR Congo. A Ugandan government spokesperson told Reuters on Thursday that the country had no active Ebola cases, a status it reaffirmed after the WHO declared Uganda Ebola-free in August.

The Africa Centres for Disease Control and Prevention is investigating a potential link to Kenya. Dr. Wessam Mankoula, the organization's head of emergency preparedness and response, noted that both the Nigerian patient and a Kenyan case traveled through Uganda's Entebbe airport on 3 October. Catherine Smallwood, a WHO Ebola incident manager based in DR Congo, said via video link to a UN briefing in Geneva that a Kenyan connection is possible. She added that officials must compare the timing of that airport transit with the onset of the Nigerian patient's symptoms to determine if the infection occurred there.

Epidemiologists remain cautious about the airport theory. Marion Koopmans, a Dutch virologist and member of the WHO's Ebola emergency committee, described the hypothesis as speculative without evidence of shared space. She stated that a random presence at a large airport is not a supported epidemiological link under current standards. In Abuja, Health Minister Muhammad Ali Pate said the case is contained and contact tracing is ongoing. He stated, "We are trying to contain it so it doesn't go out to the communities."

The Bundibugyo strain, first announced on 15 May, has infected more than 9,500 people and killed nearly half of them. It is the largest outbreak in DR Congo's history and the second largest globally, trailing only the 2014-16 west Africa epidemic which infected over 28,600 people. Melaku Yirga, vice-president for Africa at Prosper Global, emphasized that confirmed cases in Kenya and Nigeria require immediate cross-border information sharing and rapid resource deployment for frontline health workers.
