Lymphocytic choriomeningitis virus (LCMV) is a viral infection that can cause fever, muscle aches, and meningitis. Synonyms for LCMV include LCM, lymphocytic meningitis, and choriomeningitis virus. The virus is transmitted through saliva, urine, and feces of infected rodents. While LCMV infections are rare, individuals who come into contact with rodents should take necessary precautions to avoid coming into contact with the virus. There is no specific treatment for LCMV, but symptoms can be managed with medication. Awareness of LCMV and its synonyms is important for individuals who work with rodents or who may come into contact with them.
