Lassa fever is an acute viral hemorrhagic 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, often 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, diarrhea, 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 3 to 21 days. Early treatment and diagnosis increase the chances of survival.
