Originally posted by gaweidert Latest recommendations from the World Health Organization say wearing a mask is not needed unless you are caring for someone with COVID-19. Latest recommendations from the CDC are different. Pick your "experts" I guess.
The WHO mentions that "depending on supplies" masks should be used by people with comorbidities (in their FAQ here
Q&A: Masks and COVID-19).
Important (but buried, because the WHO is just like that) paragraph: "In addition to these factors, potential advantages of the use of masks by healthy people in the community setting include reducing potential exposure risk from an infected person during the ‘pre-symptomatic’ period or if an infected person is asymptomatic."
So yes but no. You have to remember that the world includes more than 190 countries, all of them under the umbrella of the WHO, and not all of them capable of securing humongous amounts of medical supplies. A strong, unequivocal recommendation can lead to supply breakdown in some places - and there are risks associated with wearing masks as it makes it more likely to touch your face.
I use respirators at work at least once a week or so (typically FFP2, but sometimes I need to pull out the gas mask); they are inconvenient, uncomfortable if you use them for long periods of time and a royal
pain in summer. Use without proper knowledge will just make it easier to smear the virus all over the mask and then voilà, you touched where you shouldn't have. The WHO should put these questions front and center - not buried in a FAQ.
