- Home quarantine is an effective measure in the prevention of transmission and mortality during the pandemic. Modelling studies have found that quarantine could potentially reduce disease transmission by 44% to 81%, and mortality by 31% to 63%.
- Early implementation of quarantine increases the effectiveness of the measure.
- Measures must be taken to improve early detection of the virus :
- Training of health care workers
- Supervision of health care workers
- Comprehensive and feasible instructions for people under home quarantine
- Combining quarantine with other public health measures (e.g. social distancing, school closings, travel restrictions) is more effective then quarantine alone.

Wang J. et al presents a study done in Shenzhen, China, that collected data from 2004 participants who had traveled to epidemic areas within 14 days before being under home quarantine. The participants were selected using a stratified multistage random sampling method. Information was obtained using online questionnaires and nasopharyngeal swab specimen analysed by the 2019-nCoV Real-Time PCR kit.
Nussbaumer‐Streit B.et al present a review on the effects of quarantine of patients who have had contact with confirmed cases, who have travelled to countries with outbreaks, or who live in places with high transmission with COVID-19. It includes 29 studies, 10 of which are modelling studies, 4 of which are observational studies and 15 are modelling studies on SARS as well as MERS.
