The new coronavirus is a fragile virus that does not tolerate high temperatures and can be destroyed in 30 minutes at 56°C. It is also insensitive to acid reagents and can be killed with 84 disinfectant or Kinzin. Alcohol can also kill this virus, the general use of alcohol is aqueous solvent, its concentration is generally 75%. For industrial alcohol, because of its high concentration, at 95%-99%, the high concentration will lead to the formation of a protective film of the new coronavirus, the virus inside is not easy to kill. Therefore, when industrial alcohol is used clinically, it must be used when water is added to reach a certain concentration. There is formaldehyde in industrial alcohol, which has certain harm to human body, so when industrial alcohol is used on neo-coronavirus, it should be dispensed to a suitable concentration and avoid contact with children or unsuitable people as much as possible to avoid poisoning.
