Abstract: The central nervous system (CNS) is a target for acute viral infections, as well as a reservoir of latent and persisting viruses. Virus infections of the central nervous system are an important but likely under-diagnosed cause of neurological disease in many developing countries. Infections of the CNS are commonly due to RNA viruses that have expanded their geographic range, spread from animal reservoirs or acquired new neurovirulence properties. RNA viruses cause diseases of the CNS, which can be classified into three groups: acute infections, acute post-exposure syndromes and chronic diseases. The viral infections manifest temselves with diverse clinical symptoms, which are often common tp many other diseases. This article presents current knowledge about epidemiology and clinical presentation of RNA virus infections in the central nervous system.
