Low-certainty evidence shows that quarantine for people exposed to confirmed or suspected COVID-19 cases prevented 44% to 81% of incident cases and 31% to 63% of deaths, compared with situations of no measures. Moreover, the sooner the quarantine measures were implemented, the greater the cost savings were. High-confidence evidence showed that clear communication about infection control and prevention guidelines was vital for successful implementation. Low-certainty evidence showed that healthcare professionals with long gowns were less exposed to contamination than were those using coveralls. In addition, coveralls were more difficult to doff. Further SRs on controlling the dissemination of COVID-19 infection are desirable.
