75% alcohol sprays are useful against new coronaviruses and have the ability to inactivate the virus. According to the Diagnostic and Treatment Program for Pneumonia Infected by Novel Coronaviruses (Trial Fifth Edition), currently available lipid solvents such as 75% ethanol, peroxyacetic acid, and chloroform are effective in inactivating the virus. Therefore, 75% alcohol spray has an inactivating effect on the new coronavirus. As an enveloped virus, alcohol can denature the protein shell of the new coronavirus, thus achieving the effect of disinfection. The disinfecting effect of too high or too low concentration of alcohol will be reduced instead, so it is recommended to use 75% alcohol for disinfection. Alcohol has an inactivating effect on the new crown virus, but because it is flammable and explosive, spraying it over a large area can easily cause a fire, so it is best to wipe it over a small area.
