Lymphocytic Choriomeningitis (LCM)


Mice and Humans

Overview / Symptoms

  • Caused by lymphocytic choriomeningitis virus (LCMV), which lives in house mice (Mus musculus) and sometime pet rodents
  • Humans most often contract LCMV from house mice, but some cases of infection from pet rodents have been reported
  • Infections can occur following exposure to infected urine, feces, saliva, or nesting materials of rodents
  • Pregnancy-related infections in humans have been associated with birth defects including hydrocephaly, chorioretinitis, and mental retardation
  • There is no treatment for rodents with LCMV, thus most recommendations when encountered in laboratory or pet rodents is to euthanize
