Neocoronaviruses may be transmitted through air conditioning. Neocoronavirus is a new coronavirus, and its main modes of transmission are respiratory droplet transmission and contact transmission. Transmission through air conditioning is relatively rare, but it cannot be ruled out. For example, when a brand-new air conditioner is being transported, droplets from infected people with the new coronavirus are deposited on the surface of the air conditioner, and other people come into contact with the air conditioner, which causes the spread of the virus. Or in places where there are relatively dense crowds, a central air-conditioner with return air circulation, which circulates the virus that may be contained in the air, thus causing transmission. The essence is the spread of contact with objects as well as aerosol transmission, except that the air conditioner may act as a medium in the transmission process. It is recommended to wear a good mask on a daily basis, try not to go to places where people gather, and go to the hospital promptly if you have symptoms such as fever and sore throat.
