| Summary: | This systematic review studies the resource use implications associated with physical interventions used for interrupting or reducing the spread of respiratory viruses, and serves to inform decision-makers when considering these interventions. It complements the updated Cochrane Review, Physical interventions to interrupt or reduce the spread of respiratory viruses (Jefferson 2011), which shows that physical interventions to interrupt or delay the spread of viruses are effective in protecting against viral transmission. The primary and secondary research questions for this work follow.1. Primary Research Question What are the resource use implications (e.g., number of units) associated with physical interventions (e.g., screening at ports of entry, isolation, quarantine, social distancing, barriers, personal protection [wearing masks, gloves, and gown], hand hygiene) used for the interruption of or reduction in the spread of respiratory viruses?2. Secondary Research Question What are the economic implications (e.g., total cost and cost-effectiveness ratios) associated with physical barriers used for interrupting or reducing the spread of respiratory viruses?
