The new coronavirus is not afraid of the cold, the coronavirus can be stored at -60°C for several years, and the virus is moderately stable in a suitable maintenance solution at 4°C. As the temperature increases, the resistance of the virus decreases, but a certain temperature must be reached and exceeded for a corresponding period of time to inactivate the virus. The new coronavirus is heat sensitive, and when a temperature of 56°C is reached for 30 minutes, the virus can be effectively inactivated. It should be noted that the usual use of air conditioning to raise the ambient temperature is unlikely to achieve the effect of inactivating the virus.
