Lymphocytic Choriomeningitis
Key Points
In humans, lymphocytic choriomeningitis is usually acquired via exposure to dust or consumption of food contaminated by mouse or hamster excreta. Most patients have no or minimal symptoms, but some develop a flu-like illness, and a few develop aseptic meningitis. Infection during pregnancy may cause fetal abnormalities; if infection occurs during the 1st trimester, the fetus may die.
