The polyomavirus simian virus 40 (SV40) is a known oncogenic DNA virus which induces primary brain and bone cancers, malignant mesothelioma, and lymphomas in laboratory animals. Persuasive evidence now indicates that SV40 is causing infections in humans today and represents an emerging pathogen.
Natural exposure to SV40 in humans is considered a rare event, and antibodies to SV40 can be demonstrated only in people who have been in contact with monkeys (Shah, 1966; Engels et al., 2004a) or who had received, in the past, SV40-contaminated poliovirus vaccine.
