WHO are still (1) telling people that they don't need to wear protection on their faces unless they're having overt symptoms of the disease or caring for someone who is, and (2) downplaying aerosols as a possible factor in transmission, despite known superspreading events associated with e.g. people singing in a choir (where, last I checked, you don't have a lot of coughing or sneezing). This sort of stuff has real consequences.
