>>12195181Could someone give us a brief summary where do we strand with masks?
There was already several studies, which detected different efficiencies depending on the masks.
So, the several question interesting to answers will be:
-Do we have solid proof that surgical mask correctly worn will protect other from covid?
-Do we have solid proof that homemade/tissues mask correctly worn will protect other from covid?
-Do we know if mask incorrectly worn or old mask are still efficient?
-Do we know if we can contract covid in open street? Should we wear mask in the city street?
Other inputs would be welcome! I will be happy to have the opinion of someone with some valuable knowledge... because for the moment, the information are disparate and it is difficult to know where science stand on this question.
