Lymphocytic choriomeningitis
Lymphocytic choriomeningitis (LCM), is a rodent-borne viral infectious disease that presents as aseptic meningitis, encephalitis or meningoencephalitis. Its causative agent is the Lymphocytic Choriomeningitis Virus (LCMV), a member of the family Arenaviridae. The name was coined by Charles Armstrong in 1934.
