According to the CDC website the Corona Virus is transmitted through the air as follows:

The main route of transmission of COVID-19 is through respiratory droplets generated when an infected person coughs or sneezes. Any person who is in close contact with someone who has respiratory symptoms (e.g., sneezing, coughing, etc.) is at risk of being exposed to potentially infective respiratory droplets. Droplets may also land on surfaces where the virus could remain viable for several hours to days. Transmission through contact of hands with contaminated surfaces can occur following contact with the person’s mucosa such as nose, mouth and eyes. Feb 25, 2021
