Minute Virus of Mice (MVM) is a variety of parvovirus occurring in rodents such as mice. MVM is a common infection in laboratory mice due to its highly contagious nature as it spreads rapidly if not addressed.
The virus can be shed from infected mice via feces and urine, but also via fomites and nasal secretions. MVM, as with most parvoviruses, is highly contagious and able to persist on environmental surfaces for long periods of time
Typically there are no clinical signs of infection, however, if infection occurs early in life, the virus can cause multiple organ damage during fetal development or shortly after birth. As a result, detection among laboratory populations can be difficult.
