Viral meningitis and encephalitis

Viruses are a major cause of central nervous system (CNS) infection worldwide. Meningitis and encephalitis commonly present with headache and fever. Encephalitis also causes neurological deficits, reflecting the involvement of the brain parenchyma. Meningitis affects the meninges alone. Enteroviruses are the most common cause of meningitis in the UK, and herpes simplex virus 1 (HSV)-1 is the most common cause of encephalitis. However, the epidemiology of viral meningitis and encephalitis varies widely across the world, with many arboviruses responsible for CNS infection.
