The pathogenicity of Omicron virus decreased, but it spread rapidly and was highly infectious. If one person in the family is "Yang", does the whole family want to be "Yang"? How to protect family members living together when their families are infected with COVID-19? In this regard, the reporter of People's Network interviewed Xiang Qian, Deputy Director of Infection Control Center of Sichuan Provincial People's Hospital, Sichuan Academy of Medical Sciences. Independent room for home therapists The home therapists should live in a relatively independent room of the family as much as possible, and use a separate toilet. Family members who live together should avoid contact with the home therapists. The home therapists should not go out or receive visits unless necessary, and try not to contact other family members. If the family members living together must contact with the home treatment personnel, or deal with their pollutants and contaminated object surfaces, they should do a good job of self-protection, wear N95 masks and disposable gloves, keep a distance of more than 1 meter from them, and do a good job of hand hygiene. Home therapists should wear masks when entering the public area of the home. If the home therapists are nursing mothers, they can continue to breastfeed the baby on the basis of personal protection. Households that do not share household articles should be equipped with personal protective equipment and disinfection products such as thermometer, paper towels, masks, disposable gloves, disinfectants, etc. More than one thermometer should be prepared and used separately by home therapists and fellow family members. Each room shall be ventilated by closing the door and opening the window independently. The room shall be ventilated by opening the window at least once a day in the morning and afternoon for more than 30 minutes each time. Mechanical ventilation such as exhaust fan shall be used if natural ventilation is unavailable. Do a good job in household disinfection of tableware: tableware should first be boiled for disinfection for 15 minutes, or it can be soaked in a chlorine containing disinfectant solution containing 250~500mg/L of effective chlorine for 15 minutes, and then washed with clean water. Disinfection of article surface: wipe the surface of articles that may be used daily, such as worktops, door handles, telephones, switches, hot water kettles, wash basins, and toilets, with chlorine containing disinfectant containing 250~500mg/L of effective chlorine, and then wash with clean water at least once a day. Disinfection of towels, clothes and quilt covers: When the towels, clothes and quilt covers of home therapists need to be cleaned, thermal drying is preferred for effective disinfection, or laundry detergent or disinfectant with disinfection function is selected for fabric cleaning according to instructions. Disinfection of toilet: if the toilet is shared with the home treatment personnel, use chlorine containing disinfectant containing 250~500mg/L effective chlorine to wipe and disinfect for 30 minutes on the basis of cleaning first. Domestic garbage disposal: paper towels, masks, disposable gloves and other domestic garbage used by home treatment personnel are put into plastic bags, and then washed or disinfected. Disinfection of objects contaminated by saliva, sputum, etc.: On the basis of wearing gloves and masks, first clean the visible pollutants, and then wipe (drag) the contaminated surfaces with chlorine containing disinfectant containing 500~1000mg/L effective chlorine. Wash hands or disinfect hands after handling. (Outlook New Times)
