Human pathogenic viruses of the polyoma type were discovered only in the 70s of the 20th century. So far seroepidemiologic researches concerning these infections have been carried out on small groups and probably are not representative of the entire of population. They showed a past polyomaviruses infection in 35–85% people in a healthy population. In two cases: JSV and BKV reactivation plays a role in a development of diseases in people with impaired immunological response, e.g. HIV infection history.
