Uganda has called for more detailed travel and medical information from Nigeria as health authorities investigate where a woman diagnosed with Ebola in Abuja contracted the virus. The Ugandan Ministry of Health says the country has no confirmed active Ebola cases and warns that transit through its territory alone does not establish where the infection occurred.

In a statement issued on Tuesday, Uganda’s Director-General of Health Services, Charles Olaro, said the woman had travelled to eastern Democratic Republic of the Congo for business before passing through Uganda in early October. According to the ministry, she showed no symptoms while in Uganda but became ill after arriving in Nigeria.

The ministry said the circumstances surrounding the woman’s exposure remained under investigation. It maintained that establishing the likely source of infection would require further evidence, rather than assumptions based solely on her travel route.

Ugandan health officials also said Nigeria had yet to provide a detailed account of the woman’s itinerary and clinical history. The information, the ministry explained, would help investigators assess the case and determine whether additional contact tracing or other public health measures were necessary.

Nigeria’s Coordinating Minister of Health and Social Welfare, Ali Pate, confirmed on Tuesday that laboratory tests had established an Ebola infection in the woman, who had recently arrived on an international flight from Uganda. He said she had received treatment at a private hospital in the Federal Capital Territory before the infection was confirmed and was subsequently placed in isolation for medical care.

Pate also announced that Nigerian authorities had identified 44 close contacts for monitoring as part of efforts to contain possible transmission. Meanwhile, Uganda said it would strengthen screening and public health controls at its points of entry, while urging residents to remain calm, maintain good hand hygiene and follow preventive measures.

The investigation comes amid renewed concern over Ebola in parts of East Africa, following Kenya’s confirmation in October of its first case of Ebola Bundibugyo virus disease. For now, the source of the Nigerian patient’s infection remains unresolved, underscoring the importance of timely information-sharing between countries to support contact tracing and prevent further spread.
