Lassa viruses are enveloped, single-stranded, bisegmented, ambisense RNA viruses. Their genome is contained in two RNA segments that code for two proteins each, one in each sense, for a total of four viral proteins.he well-known Lassa fever is mostly caused by the Lassa virus. The symptoms include flu-like illness characterized by fever, general weakness, cough, sore throat, headache, and gastrointestinal manifestations.
In areas of Africa where the disease is endemic (that is, constantly present), Lassa fever is a significant cause of morbidity and mortality. While Lassa fever is mild or has no observable symptoms in about 80% of people infected with the virus, the remaining 20% have a severe multisystem disease. Lassa fever is also associated with occasional epidemics, during which the case-fatality rate can reach 50%.
