Several adjunctive infection prevention methods are in common use but their effectiveness in reducing healthcare-associated respiratory viral infections is unclear. In this review, recent advances regarding the effectiveness of several adjunctive infection prevention methods to reduce healthcare-associated respiratory viral infections are discussed. Recent findings Training and education on hand hygiene guidelines, mandatory influenza vaccination for healthcare personnel, access to paid sick leave to reduce ill presenteeism, cohorting of patients with the same infection or clinical syndrome, neuraminidase inhibitor chemoprophylaxis during influenza outbreaks, and enhanced visitor restrictions in pediatric hospitals all have shown some degree of effectiveness in observational or quasi-experimental studies. Summary Most of the studies evaluating the effect of adjunctive infection prevention methods on healthcare-associated respiratory viral infections are observational or quasi-experimental and are often combined with other interventions. Therefore, it is difficult to determine the precise effectiveness or efficacy of these interventions and more controlled trials are needed. Multimodal infection prevention policies are likely to be most effective in reducing healthcare-associated respiratory viral infections. Copyright © 2020 Wolters Kluwer Health, Inc.
