LCM viruses, also known as lymphocytic choriomeningitis viruses, are a group of viruses that are commonly found in rodents, particularly mice. They belong to the Arenaviridae family and include several strains, such as LCMV-Clone 13 and Armstrup.
LCM viruses have a unique ability to infect humans, although these infections are relatively rare. These viruses are typically transmitted to humans through direct or indirect contact with the urine, droppings, saliva, or nesting materials of infected mice. In some cases, humans may also contract LCM viruses through inhaling dust contaminated with virus particles.
Infection with LCM viruses can cause a wide range of symptoms, ranging from none or very mild to more severe illness. Mild symptoms may include fever, headache, muscle aches, and vomiting, which can easily be mistaken for the flu. However, in severe cases, individuals may experience more serious symptoms, such as meningitis (inflammation of the membranes surrounding the brain and spinal cord) or encephalitis (inflammation of the brain). Pregnant women who become infected with LCM viruses may also be at risk of miscarriage or birth defects.
There is currently no specific treatment or vaccine available for LCM virus infections in humans. However, supportive care can be provided to manage symptoms and complications. Prevention of LCM virus infections largely revolves around proper sanitation and hygiene practices, especially in environments where rodents are present. This includes safely cleaning areas contaminated with rodent droppings, storing food in secure containers, and sealing any possible entry points for rodents.
