"Masks alone cannot stop the #COVID19 pandemic. Countries must continue to find, test, isolate and treat every case and trace every contact," says @DrTedros
#coronavirus at @WHO #COVID19 briefing 6 Apr.

"We encourage countries that are considering the use of masks for the general population to study their effectiveness so we can all learn.

But most importantly, #masks should only be used as part of a comprehensive package of interventions," - @DrTedros at @WHO #COVID19 briefing.
