In March 2020, the South African government implemented various non-pharmacological prevention and control measures (e.g. isolation, social distancing and quarantine) in response to the COVID-19 pandemic. We summarise evidence from a rapid Cochrane review on the effect of quarantine alone v. quarantine plus combination measures to prevent transmission of and mortality caused by COVID-19. The findings show that when started earlier, quarantine combined with other prevention and control measures can be more effective than quarantine alone, and cost less.
