This evidence summary provides an overview of and supporting evidence for the public health measures (PHMs) that can help to reduce transmission of SARS-CoV-2, the virus that causes COVID-19, in community-based settings, places where people live, work, learn and play.
Individual public health measures are effective actions you can use every day to help reduce the spread of COVID-19. These measures are also sometimes called personal preventive practices. It's most effective to use several measures at once, which is called layering.

Understanding how SARS-CoV-2, the virus that causes COVID-19, is transmitted helps to determine the approach to a risk assessment and implementation of corresponding risk mitigation measures to help to reduce the spread of COVID-19. For more information refer to PHAC's modes of transmission webpage. Risk assessment and mitigation for COVID-19.
All four reported reductions in SARS-CoV-2 transmission as a result of isolation measures. Designs included a retrospective cohort study, a natural experiment and two cross-sectional studies. Quarantine was assessed in two cohort studies with low and moderate risk of bias ratings.
