Category:Polyomaviridae

Polyomaviridae is a family of viruses. Mammals and birds serve as natural hosts. There are currently 13 species in this family, divided among 1 genera, Polyomavirus (type species Simian virus 40). Diseases associated with this family include: JCPyV: progressive multifocal leukoencephalopathy; BKPyV: mild respiratory infection. They are potentially oncogenic (tumor-causing); they often persist as latent infections in a host without causing disease, but may produce tumors in a host of a different species, or a host with an ineffective immune system. The name polyoma refers to the viruses' ability to produce multiple (poly-) tumors (-oma).
