How to disinfect effectively to prevent and control COVID-19?
How to disinfect effectively to prevent and control COVID-19? An important step in the prevention and control of new coronavirus pneumonia is to carry out scientific and effective disinfection, and it should be noted that disinfectants are irritating and corrosive.
1 Frequently touched surfaces of public goods such as door handles, telephones, mobile phones, TV remote controls, desktops, and the ground should be wiped or washed with a clean wet towel and disinfected if necessary.
2 Places where confirmed cases and asymptomatic infected persons have lived, such as homes, isolation wards of medical institutions, transfer tools, etc., shall be disinfected at any time; after the case is discharged or died, the nucleic acid test of asymptomatic infections shall be thoroughly disinfected.
3 Disinfect the surface of the object. First, remove visible contaminants, and then use chlorine-containing disinfectant for spraying, wiping or soaking disinfection. After 30 minutes of action, wipe clean with clean water.
4 Disinfection of household items. For household items such as tableware, clothes, bedding, boil for 30 minutes, or soak in a chlorine-containing disinfectant for 30 minutes, and then rinse with clean water.
5 Indoor air disinfection. Indoor air disinfection can choose disinfectant spray disinfection such as peracetic acid, chlorine dioxide, hydrogen peroxide, etc., or it can be disinfected by ultraviolet radiation for more than 1 hour.
6 Disinfect indoor floors and walls. First, remove visible contaminants, and then wipe or spray with chlorine-containing disinfectant. For ground disinfection, spray once from the outside to the inside. After the indoor disinfection is completed, spray again from the inside to the outside. The disinfection time should be no less than 30 minutes.
7 Disinfection of patient’s vomit, excreta and secretions. Pollutants that directly contaminate the ground can be carefully removed by dipping gauze, rags, etc. with a certain concentration of chlorine-containing disinfectant, put them in a special container, and soak in a high-concentration chlorine-containing disinfectant for at least 2 hours. After removing the contaminants, the contaminated environmental objects and containers should be disinfected, and hands should be cleaned and disinfected at the same time.
