Understanding lymphocytic choriomeningitis (LCM) risks

Lymphocytic Choriomeningitis (LCM) is a rare viral infection that affects the brain and nervous system. Understanding its causes, symptoms, and prevention can protect your health.

What are the main causes of lymphocytic choriomeningitis (LCM)?

• LCM is primarily caused by exposure to infected rodents, particularly common house mice, which carry the virus in urine, droppings, and saliva.
• Human infection can occur through inhalation of virus-contaminated dust or direct contact with rodent excretions.
• Less commonly, LCM may be transmitted through organ transplantation or blood transfusions from infected donors.

Key symptoms of lymphocytic choriomeningitis (LCM) to watch for

• Early signs include fever, fatigue, muscle aches, and headaches, often appearing one to two weeks after exposure.
• Severe cases can progress to neurological symptoms such as meningitis, encephalitis, or confusion.
