Lassa Fever

Lassa fever is a viral disease caused by the Lassa virus. It is transmitted to humans and animals through contact with infected rodents and their excreta, or by inhalation or ingestion of the virus. Symptoms of Lassa fever include fever, muscle or joint pain, abdominal pain, and nausea. In severe cases, the disease can cause hearing loss, encephalitis, seizures, and even death. Lassa fever is endemic in West Africa, especially in Nigeria. In recent years, there have been efforts to improve diagnosis and treatment of the disease, as well as to limit its spread. Diagnosis is made through laboratory testing of blood or other bodily fluids. Treatment is with antiviral medications and supportive care. Vaccine development is ongoing. Lassa fever is an important public health concern and an emerging global health threat. It causes significant morbidity and mortality in affected countries, and efforts must be taken to improve detection and treatment, as well as to prevent further spread.
