Dr. Msuega Asema, State Epidemiologist and Manager of the Benue State Public Health and Emergency Operation Centre (PHEOC), disclosed the data during a World Health Organisation (WHO)-organised training in Makurdi for community health workers and media professionals.
Since February 2025, the state has documented 156 suspected cases, and unlike previous years, the outbreak has continued into the rainy season, raising fresh concerns among health authorities.
“We have not deactivated our response because we are still seeing cases, even during the rainy season, which is unusual. Lassa fever is typically more common in the dry season,” Asema said.
Of the total deaths, six were lab-confirmed cases, while nine others are considered probable based on clinical presentation and exposure history, though lacking laboratory confirmation.
Asema explained that Lassa fever is primarily transmitted through exposure to the urine or faeces of infected multimammate rats (Mastomys natalensis), which commonly contaminate uncovered or poorly stored food.
WHO Warns of Worsening Outbreak and Urges Preventive Action
WHO State Coordinator Dr. Mohammed Abdulkarim expressed deep concern over the persistent presence of Lassa fever in Benue State, which he noted has endured for over six years.
“The outbreak has lingered in Benue for over six years. It is spreading fast, and we need a shift from reactive to preventive health approaches,” Abdulkarim said.
He called for increased public health funding and a greater focus on community awareness, nutrition, and hygiene practices as long-term strategies to curb the spread.
Lassa fever, an acute viral hemorrhagic illness, is endemic in several West African countries. The disease is often fatal if left untreated, and while seasonal, its continued appearance during the rainy season signals potential changes in transmission patterns that health authorities are closely monitoring.
