If this story is blocked, the essence of it is that the virus is mainly transmitted by droplets coming directly from a carrier’s coughs, sneezes or just their exhalations. Six feet of separation allows gravity to pull those droplets to the ground. BUT, in a closed indoor space, the virus can also ride on an aerosol – extremely tiny droplets that can float in the air for minutes or even hours. Hundreds or thousands of people not wearing masks and cheering wildly can generate such a miasma. This may be how Trump got infected in spite of otherwise stringent precautions.
