Disinfection at home can be done with alcohol. The resistance of the new coronavirus pneumonia is relatively not very strong, as clearly mentioned in the latest version of the fifth edition of the treatment guidelines, the new coronavirus pneumonia is not resistant to heat or ultraviolet light, and can be disinfected by means of ether, medical alcohol i.e. 75% anhydrous ethanol, chlorinated disinfectant, and high temperature. Medical alcohol wipe disinfection can be used at home because it is also volatile and does not leave a smell and is relatively non-corrosive. For clothing surfaces, cell phones, car interiors, etc. can also be disinfected by wiping with medical alcohol. The floor can be disinfected with bleach or 84 disinfectant, the concentration does not have to be too high, and the room should be ventilated as much as possible, with each ventilation set at about 20-30 minutes, once in the morning and once in the evening.
