WHO recommends masks indoors if ventilation poor
The World Health Organization on Wednesday recommended wearing face masks when indoors with other people, if the ventilation has been deemed inadequate, in an update to its COVID-19 guidance on masks, CTV News reports.
The new recommendations apply in areas of known or suspected cluster or community transmission of the new coronavirus.
"WHO advises that the general public should wear a non-medical mask in indoor (eg shops, shared workplaces, schools) or outdoor settings where physical distancing of at least one metre cannot be maintained," the new guidance says.
"If indoors, unless ventilation has been assessed to be adequate, WHO advises that the general public should wear a non-medical mask, regardless of whether physical distancing of at least one metre can be maintained."
