The activity of the novel coronavirus can be significantly reduced after 2 hours in vitro. The survival time of the virus in vitro is highly dependent on the temperature and humidity in the environment and the state of the virus itself. In air at 10-15°C, the virus survives for 240 minutes, and in air at 25°C, the virus survives for only 2-30 minutes. The virus is sensitive to heat and can be effectively killed by acting at 56°C for 30 minutes. In addition, ether, 75% ethanol, chlorinated disinfectants, peroxyacetic acid, etc. can also kill the virus and can effectively inactivate the virus after 30 minutes of action, and ultraviolet light can also effectively inactivate the virus.
