Lymphocytic choriomeningitis virus (LCMV) is a rodent-borne virus that primarily affects house mice. It can cause infections in humans, leading to symptoms such as fever, headache, and muscle aches. In some cases, it can progress to more severe conditions like meningitis or encephalitis. Transmission occurs through contact with infected rodent urine, droppings, or saliva, as well as through bites. Pregnant women are at risk, as the virus can affect the fetus, potentially leading to serious complications. There is no specific treatment for LCMV, so prevention focuses on reducing rodent exposure and maintaining cleanliness in living areas.
