The new coronavirus spreads commonly through droplet transmission, and the other is contact transmission, i.e., droplets fall onto the table, doorknob, and spread after hand contact. In general, it will not spread in the air, because the droplets are not more than 2 meters, even if you cough and sneeze hard, the transmission distance is also in the range of 5-8m, so it is difficult for droplets to be transmitted over long distances. If an aerosol is formed under special circumstances, the aerosol can be suspended in the air and may spread through the air. However, this type of transmission can occur in ICU wards where tracheal intubation and tracheotomy are performed on patients, and aerosols may be formed, and airborne transmission may occur. In most cases, airborne transmission does not occur. Source: Dr. Yurai
