Covid does survive in aerosols. Its R0 has been estimated around 2.5-3. Virus particles are usually smaller than 1 micron but can clump together or there can be many in a small droplet. It is easily aerosolized, can travel long distances in the air and survive for many hours. The good thing is it takes many particles to overwhelm the immune system and get a severe case.
