We investigated the effect of annual winter visitor restrictions on hospital respiratory virus transmission. The healthcareassociated (HA) viral respiratory infection (VRI) transmission index (number of HA VRIs per 100 inpatient communityassociated VRIs) was 59% lower during the months in which visitor restrictions were implemented. These data prompt consideration for instituting year-round visitor restrictions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
