Microwaving for more than a minute can also kill the new coronavirus. The new coronavirus is a single chain rna virus, fear of high temperature, high temperature can make the virus nucleic acid break, protein denaturation, resulting in the death of the virus. Generally at 56 degrees Celsius for more than 30 minutes can kill the new coronavirus, 100 degrees Celsius 1 ~ 2 minutes can kill the new coronavirus, microwave heating internal temperature is higher than 100 degrees Celsius, so microwave heating for more than a minute can kill the new coronavirus, at the same time make the new coronavirus lost the infection activity. But microwave heating time is too short, may not be able to achieve an effective effect of killing the virus. In addition ethanol and chlorine-containing disinfectants also have a killing effect on the new coronavirus.
