Reducing Contacts

Living Evidence Synthesis: What is the effectiveness of measures to reduce contacts in reducing transmission of COVID-19 and other respiratory illnesses (e.g., influenza, respiratory syncytial virus (RSV) in non-healthcare community-based settings?

Gathering restrictions, stay-at-home orders, and initial school closures may have been particularly effective to reduce transmission of COVID-19, particularly during the first wave.
