It& #39;s official. The WHO just revised the advice on wearing masks, and acknowledges that wearing a medical mask is one of the prevention measures that can limit the spread of certain respiratory viral diseases, including #Covid19. What a belated announcement https://www.who.int/publications-detail/advice-on-the-use-of-masks-in-the-community-during-home-care-and-in-healthcare-settings-in-the-context-of-the-novel-coronavirus-(2019-ncov)-outbreak">https://www.who.int/publicati...

Worth pointing out that the WHO still declines to ask people without symptoms to wear masks

It& #39;s only after the US and some European countries began asking people to wear a mask that the WHO finally revised its mask advice. Global supply chain issues are no excuse for misdirecting the public. Allocation of resources is the issue here. https://twitter.com/IsaacATFlorence/status/1247470543357579264?s=20">https://twitter.com/IsaacATFl...

Protecting ourselves and protecting medical professionals are not mutually exclusive. Look at Hong Kong for inspiration.

Some governments have all along relied on their own wisdom rather than the WHO& #39;s advice when it came to masks, such as Japan

The "it& #39;s useless unless you wear it properly" has been one of the major counterarguments used by especially British medical policymakers. I& #39;ve never heard Hong Kong doctors telling us not to wear a mask, because we were presumably to dumb to do it right. https://twitter.com/synapse101/status/1247472866037100546?s=20">https://twitter.com/synapse10...
