A very informative article 👏. You reached a conclusion that we both agree on. Wearing a mask is important. It is not perfect but it is still better than not wearing any mask. It decreases the viral load that got expelled when talking, coughing, or sneezing. I would add that one should sneeze and cough in the elbow/sleeve even when wearing a mask. To diminish (and hopefully, stop) the spread of the virus, every single preventive measure has to be followed has an overall daily behavior.
