Ebola Spread: Nigeria's New Case Sparks Dispute Over Travel Route

A disagreement between Swiss and Ugandan officials has clouded the origin of Nigeria's first Ebola case in over ten years. The conflict centers on the travel history of the patient, whose infection marks the expansion of the current outbreak into a fourth African nation. Health authorities are working to determine how the virus moved across borders while the total death toll continues to climb.

The Swiss foreign ministry stated on Friday that the patient is the Ugandan-born wife of a Swiss diplomat stationed in Abuja. According to the ministry, she did not visit the Democratic Republic of Congo, where the outbreak began in mid-May. Instead, Swiss officials believe she contracted the virus while traveling with her husband in Uganda.

This account clashes with earlier statements from Uganda. A Ugandan government spokesperson told Reuters on Thursday that the country had no active Ebola cases and would publicly report any new infections. This position contrasts with previous claims that the woman traveled to eastern DR Congo. The discrepancy has raised concerns about the ability of regional authorities to track and contain a highly mobile pathogen.

The World Health Organization and the Africa Centres for Disease Control and Prevention are investigating a potential link to a patient in Kenya. Dr. Wessam Mankoula, head of emergency preparedness at the Africa CDC, noted that both individuals passed through Entebbe airport in Uganda on October 3. However, experts are cautious. Marion Koopmans, a virologist on the WHO emergency committee, described the airport theory as speculative without proof of shared space sufficient for transmission.

The outbreak, caused by the Bundibugyo virus strain, was first announced on May 15. It has infected more than 9,500 people and killed nearly half of them. This makes it the deadliest outbreak in DR Congo's history and the second largest globally, following the 2014-16 epidemic in West Africa. There is currently no approved treatment or vaccine for this specific strain.

Nigeria's 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." Meanwhile, Melaku Yirga, vice-president for Africa at Prosper Global, emphasized the need for rapid cross-border information sharing to support frontline health workers in responding to the growing crisis.
