Nigeria Ebola Origin Dispute

Health officials across Africa are scrambling to determine how Nigeria acquired its first Ebola patient in over ten years. The case has raised alarms as the outbreak expands to a fourth country on the continent. A dispute over the patient's travel history has complicated containment efforts.

The Swiss foreign ministry stated on Friday that the infected individual is the Ugandan-born wife of a Swiss diplomat stationed in Abuja. The ministry asserted she did not visit the Democratic Republic of Congo, the epicenter of the outbreak. Instead, they believe she contracted the virus while traveling with her husband in Uganda. This account directly contradicts earlier reports from Ugandan authorities, who said the woman traveled to eastern DR Congo.

A Ugandan government spokesperson told Reuters on Thursday that the country had no active cases and would publicize any changes in that status. The World Health Organization said it is continuing investigations into the likely source of the infection. Catherine Smallwood, a WHO Ebola incident manager in DR Congo, told a UN briefing via video link that staff had no information indicating the patient had traveled to that country.

The Africa Centres for Disease Control and Prevention is examining a potential link to a Kenyan case. Dr Wessam Mankoula, the organization's head of emergency preparedness and response, noted that both patients passed through Uganda's Entebbe airport on 3 October. Smallwood said a connection was possible but required a comparison of timing with the Nigerian patient's symptom onset. Marion Koopmans, a Dutch virologist on the WHO emergency committee, called the airport theory speculative without evidence of shared space.

Nigeria's health minister, Muhammad Ali Pate, said the case remains contained. He stated that contact tracing is ongoing and that officials are working to prevent community spread. The outbreak is caused by the Bundibugyo virus, for which no approved treatment or vaccine exists.

The epidemic was first announced on 15 May and has infected more than 9,500 people, killing nearly half of them. It stands as the largest outbreak in DR Congo's history. Only the 2014 to 2016 West Africa epidemic, which infected more than 28,600 people and killed more than 11,000, has been larger. Melaku Yirga, vice-president for Africa at Prosper Global, emphasized the need for speed and cross-border information sharing to manage the crisis.
