Washington Post: Yes, airborne transmission is happening. The CDC needs to set the record straight.. “The science here is fairly straightforward. When you talk or sing — or even just breathe — you emit a range of particles of different sizes. Yes, there might be one or two particles that are large enough to see and that fall to the ground within six feet, but there are also thousands of particles that are smaller than five microns (or five millionths of a meter). Such particles stay aloft for minutes to hours and can travel all the way across a room on natural air currents. They don’t stop at six feet. They will stay in the air in the room until they are pushed outdoors by ventilation, trapped on a filter if you have one, or deposited in your lungs. More importantly, among particles that stay in the air long enough to be inhaled, those smaller than five microns actually carry more virus than the larger ones, counterintuitively.”
