The expanding family Polyomaviridae infect a variety of different hosts (1). Generally, avian polyomaviruses are highly pathogenic and have a wide host range, while mammalian polyomaviruses have a limited host range and are asymptomatic in the immunocompetent host (2, 3). At present, 13 of these species are linked to human infection, JC polyomavirus (JCPyV) (4), BK polyomavirus (BKPyV) (5), WU polyomavirus (WUPyV) (6), KI polyomavirus (KIPyV) (7), Merkel cell polyomavirus (MCPyV) (8), human polyomavirus 6 (HPyV6) (9), human polyomavirus 7 (HPyV7) (9), Trichodysplasia spinulosa-associated polyomavirus (TSPyV) (10) and human polyomavirus 9 (HPyV9) (11), Malawi polyomavirus (MWPyV) (12), St. Louis polyomavirus (STLPyV) (13), human polyomavirus 12 (HPyV12) (14), and New Jersey polyomavirus (NJPyV-2013) (15). Zoonotic infections have not been reported, however they cannot be completely excluded.
