How many mice have LCMV?

It is estimated that 1 out of 20 house mice (5%) in the United States carry LCMV. The Centers for Disease Control and Prevention (CDC) estimate that 1 out of 20 to 1 out of 50 adults (2% – 5%) have had an LCMV infection. What are the symptoms of LCMV? Some people with LCMV have no symptoms.

Do all mice have LCMV?

The primary host of LCMV is the common house mouse, Mus musculus. Infection in house mouse populations may vary by geographic location, though it is estimated that 5% of house mice throughout the United States carry LCMV and are able to transmit virus for the duration of their lives without showing any sign of illness.

How long does LCMV live in mouse droppings?

Mice and hamsters can become persistently infected with LCMV if they are exposed either in utero or soon after birth. Older animals usually clear the virus completely. Persistently infected mice can shed LCMV lifelong, while hamsters may excrete it for at least 8 months.

How do you know if you have LCMV?

What are the Symptoms? Symptoms of LCMV infection are similar to those for influenza and include fever, stiff neck, a lack of appetite, muscle aches, headache, nausea and vomiting and occur 1–2 weeks after exposure to an infected rodent.

Can a mouse get lymphocytic choriomeningitis ( LCM )?

LCM is usually not fatal. In general, mortality is less than 1%. Individuals of all ages who come into contact with urine, feces, saliva, or blood of wild mice are potentially at risk for infection.

What are the early signs of lymphocytic choriomeningitis?

The initial signs are nonspecific and may include fever, anorexia, dyspnea, weakness and lethargy. Jaundice is characteristic and petechial hemorrhages may develop. These signs are often followed by prostration and death. In rodents, LCMV is shed in urine, saliva, feces, milk and semen.

How does a person get lymphocytic choriomeningitis ( MSD )?

Most people become infected when they inhale dust or eat food contaminated with the urine, feces, or another body fluid of an infected mouse or hamster.

Can you get lymphocytic choriomeningitis from a hamster?

Other types of rodents, such as hamsters, are not the natural reservoirs but can become infected with LCMV from wild mice at the breeder, in the pet store, or home environment. Humans are more likely to contract LCMV from house mice, but infections from pet rodents have also been reported.
