The duration of survival of the novel coronavirus in air or indoors has not been determined. The virus may remain infectious for up to 5 days in a dryer, better environment, but further testing and clinical trials are needed to confirm the actual situation. Viruses can indeed survive for a longer period of time in a suitable environment outside the body, for example, SARS viruses are known to survive for 2 days on the surface of a dry object and 3 days indoors. For example, the SARS virus is known to survive for 2 days on a dry surface and 3 days indoors. It can survive for 4 days at 37°C, even without serum culture. Now there is no clear result on the survival time of the new coronavirus. It is necessary to pay attention to good protection, minimize going out, and open windows more often to avoid mutual infection and other problems. Content source: Dr. You Lai
