Nigeria Confirms Ebola Case in Swiss Diplomat's Wife as Origin Dispute Deepens

Nigeria has confirmed its first Ebola case in more than ten years, identifying the patient as the Ugandan-born wife of a Swiss diplomat stationed in Abuja. Health officials in Switzerland, Nigeria, and Uganda are currently divided on how the woman contracted the virus, creating uncertainty as the outbreak spreads to a fourth African nation.

The Swiss foreign ministry stated on Friday that the patient had not traveled to the Democratic Republic of Congo, where the epidemic began in mid-May. The ministry believes she caught the infection while traveling with her husband in Uganda. This account directly conflicts with earlier reports from Ugandan authorities, who said the woman had visited eastern DR Congo. A Ugandan government spokesperson told Reuters on Thursday that the country had no current Ebola cases and would release information if that changed.

The Africa Centres for Disease Control and Prevention is investigating a potential link to a patient in Kenya. Dr. Wessam Mankoula, the organization's head of emergency preparedness, said both individuals passed through Entebbe airport in Uganda on 3 October. Catherine Smallwood, a WHO Ebola incident manager based in DR Congo, told a UN briefing in Geneva that her team had no data showing the patient visited DR Congo. She noted that officials must compare the timing of the airport encounter with the onset of the Nigerian patient's symptoms to determine if infection occurred there.

Some experts remain skeptical of the airport connection. Marion Koopmans, a Dutch virologist on the WHO's Ebola emergency committee, described the theory as speculative without proof that the two shared a specific space. She argued that a random presence at a large airport does not meet the epidemiological standards for a confirmed link.

Muhammad Ali Pate, Nigeria's health minister, said the case is contained and contact tracing is ongoing. "We are trying to contain it so it doesn't go out to the communities," he said. Melaku Yirga, vice-president for Africa at Prosper Global, emphasized the need for rapid cross-border information sharing and adequate resources for frontline health workers to manage the spread.

The outbreak is driven by the Bundibugyo virus, a strain with no approved vaccine or treatment. First announced on 15 May, the epidemic has infected more than 9,500 people and killed nearly half of them. It stands as the deadliest outbreak in DR Congo's history and the second largest globally, trailing only the 2014-16 west Africa epidemic that infected over 28,600 people and killed more than 11,000.
