Lassa Fever Claims 109 Lives in Nigeria in 2026 Outbreak

In the first nine weeks of 2026, Lassa fever has resulted in 109 fatalities across Nigeria, marking a significant increase in cases, particularly among health workers, with 37 infections reported. The Nigeria Centre for Disease Control (NCDC) indicated that six health workers were affected in just one week.

The outbreak spans 18 states and 69 local government areas, with the highest incidence in Bauchi, Ondo, Taraba, Benue, and Edo. Lassa fever, characterized by acute febrile illness, presents symptoms that can complicate early diagnosis.

Despite previous containment efforts since the disease was first identified in Borno State in 1969, recent outbreaks have highlighted deficiencies in response capacity and surveillance, as noted by the World Health Organization. Contributing factors to the high fatality rate include poor health-seeking behavior and environmental sanitation.

Experts recommend improved food safety practices and regular handwashing. The article emphasizes the need for coordinated efforts among stakeholders to effectively manage and prevent future outbreaks.
