Multiple strains of enteric viruses co-circulate in pediatric patients with gastroenteritis, highlighting the importance of routine screening and infection control to prevent nosocomial infections.
May warrant vigilance for co-infections in pediatric wards; leaves open whether screening reduces nosocomial transmission.
The genetic diversity of enteric viruses co-circulating in a cohort of patients with viral gastroenteritis in a large tertiary paediatric hospital in London, UK, was determined. Multiple strains of noroviruses (NV), sapoviruses (SV) and astroviruses (HAsV) were detected in these patients, indicating the likelihood of multiple introductions from different sources, possible sub-clinical infections and simultaneous infection with different viruses in immunocompromised and other patients. Routine screening of immunocompromised patients and infection control procedures are important to prevent nosocomial infection.
