Lassa fever is an acute viral haemorrhagic illness transmitted to humans through contact with food or household items contaminated by rodents infected with the Lassa fever virus. Person-to-person transmission can also occur, particularly in a hospital environment with inadequate infection control measures.

Like several other countries in West Africa, the disease is endemic in Nigeria and is often recorded during the dry season between November and May.

Lassa fever presents initially like any other febrile illness, such as malaria. Its symptoms include fever, headache, sore throat, general body weakness, cough, nausea, vomiting, diarrhoea, muscle pains, chest pain, and in severe cases, unexplainable bleeding from ears, eyes, nose, mouth, and other body openings.

The time between infection and the appearance of symptoms of the disease is between three to 21 days. However, early treatment and diagnosis increase the chances of survival.

To reduce the risk of the spread of Lassa fever, the NCDC has advised Nigerians to ensure proper environmental sanitation; dispose of refuse properly, store foodstuff like rice, garri, beans, and corn among other raw foods in containers with tight-fitting lids.

Nigerians are also urged to avoid bush burning, eliminate rats in homes and communities by setting rat traps and other means, and practice good personal hygiene by frequent handwashing with soap under running water or use of hand sanitisers when appropriate.

The centre urges Nigerians to visit the nearest health facility if they notice any of the signs and symptoms of Lassa fever, and avoid self-medication.

It is also advised that health care workers practice standard precautions and to maintain a high index of suspicion at all times.
