About Lassa Fever
Hemorrhagic viral disease, commonly known as Lassa fever, is transmitted to humans through contact with contaminated food or household items that are infected or even direct contact with its patient.
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.
