more-lifestyleUpdated: Jun 01, 2020 13:46 ISTChinese researchers have suggested that wearing face masks at home is 79 per cent effective at preventing COVID-19 spread among family members in the same household. Each family had at least one laboratory-confirmed case of COVID-19 infection between late February and late March 2020. During this time, secondary transmission--spread from the first infected person to other family members--occurred in 41 out of the 124 families. The findings showed that a face mask worn before symptoms started was 79 per cent effective, and disinfection 77 per cent effective, at stopping the virus from being passed on. The findings back universal face mask use, not just in public spaces, but also at home.
