Abstract

Evidence of Simian virus 40 (SV40) DNA sequences or gene products has been reported in a variety of organ systems in humans. However, the route of transmission and the significance of SV40 polyomavirus infection in human are unknown. The aim of study was to characterize the frequency of SV40 infection in immunocompetent and immunocompromised patients with respiratory diseases. Respiratory specimens from patients with respiratory tract illness obtained from nasopharyngeal aspirates (n = 280) were screened for SV40 polyomavirus using real-time PCR; coinfection with other viruses was examined. Positive results were confirmed with sequencing. Of the 280 samples analysed, 2 (0.71%) were positive for SV40. SV40 was identified in nasopharyngeal aspirate samples from children aged 8 and 14 months who were immunocompetent. Both patients had upper or lower respiratory tract infection. Coinfections with other viruses were found in 50% of the SV40 positive samples. The data suggest that SV40 can infect respiratory tract, that respiratory tract may represent a route of transmission or a site for virus persistence, and that with the high rate of co-infection, SV40 may not involved in respiratory diseases. © 2022 Wiley Periodicals LLC.
