WHO said January 15 that there was no Human-Human spread of SARS-CoV-2. They are a politicized organization and you should not depend on what they have to say for unbiased factual information. There is ample scientific evidence that masks work both to prevent being infected and to prevent infecting others. The argument seems to be "there is sufficiently low risk from normal daily activities that it's not worth wearing a mask." If that's the case, why can't I leave my house except for groceries? How did all of those people catch this thing if the risk is so low? The reality is that the risk for everyone, given the severity of COVID is high. The risk for healthcare workers is beyond extreme.
