Response efforts
The NCDC reported that it has activated the National Lassa Fever Incident Management System to coordinate the country’s response to the outbreak.
National Rapid Response Teams have also been deployed to affected states to support control and management efforts using a “One Health” approach, which integrates human, animal, and environmental health interventions.
About Lassa fever
Lassa fever is a viral hemorrhagic disease transmitted to humans through contact with food or household items contaminated by infected rodents. It can also spread through direct contact with infected individuals.
Symptoms include fever, headache, sore throat, weakness, nausea, vomiting, diarrhoea, and muscle pains. Severe cases may involve unexplained bleeding from body openings such as the nose, mouth, and ears.
The NCDC urged Nigerians to maintain proper hygiene, store food in rodent-proof containers, and seek medical attention immediately when symptoms appear.
