Abstract
supply worldwide, cloth face coverings can be used as an additional, voluntary public health measure. Third, once asymptomatic infections have been confirmed, self-quarantine is necessary, and these cases should be required to monitor their health status daily, to contact and follow the advice of their medical provider, and to stay home or wear a mask and remain 2 m away from other people if they go out. Because the rate of asymptomatic SARS-CoV-2 infection may be high among the close contacts of a symptomatic patients, these contacts should be closely monitored to rule out infection, even if they remain asymptomatic. Finally, scientists and public health experts should conduct research on SARS-CoV-2 to quickly improve the detection capacity and to achieve mass testing of citizens, especially those living in large enclosed facilities and those living and working in high-risk facilities (eg, healthcare workers).
