Disinfectant use guide

The new type of coronavirus belongs to the β genus of coronaviruses, and its genetic characteristics are significantly different from SARSr-CoV and MERSr-CoV. There is currently no direct data on the resistance of the new coronavirus. Based on previous understanding of the coronavirus, all classic disinfection methods should be able to kill the coronavirus. When the SARS epidemic broke out in 2003, the World Health Organization only mentioned in the relevant guidelines that ultraviolet light had a poor killing effect on the coronavirus; for this new type of coronavirus, only chlorhexidine was not effective.

    Disinfectant is a preparation used to kill microorganisms on the transmission medium to achieve disinfection or sterilization requirements. According to the active ingredients, it can be divided into alcohol disinfectants, chlorine disinfectants, iodine disinfectants, peroxide disinfectants, guanidine disinfectants, phenol disinfectants, quaternary ammonium salt disinfectants, etc.; can be divided by purpose It is surface disinfectant, medical device disinfectant, air disinfectant, hand disinfectant, skin disinfectant, mucous membrane disinfectant, foci disinfectant, etc.; according to the ability to kill microorganisms, it can be divided into high-level disinfectant and medium-level disinfection. Agents and low-level disinfectants.

    During the prevention and control of the new coronavirus pneumonia epidemic, disinfectants should be used rationally, and the "five strengthening and seven unsuitable" should be followed to truly cut off the route of transmission and control the spread of infectious diseases. "Five enhancements": Isolation wards and patient residences should be disinfected at any time and terminal disinfection; the surface of environmental objects in densely populated places such as hospitals, airports, stations and other places should be disinfected more frequently; door handles and elevator buttons with high frequency contact should be strengthened for cleaning and disinfection; Garbage, feces and sewage are collected and harmlessly treated; personal hand hygiene should be done well.
