During the period of living at home, positive family members may infect each other, which will cause repeated infection? After home, how to disinfect the room? Chen Zhi, Chief Physician of Beijing Emergency Center and Secretary General of the Emergency Center (Station) Branch of the Chinese Hospital Association, recently reminded that convalescent patients with negative antigen self-test for three consecutive days can no longer live alone. After finishing living at home, the toilet, washbasin and other key parts should be disinfected with alcohol or chlorine containing disinfectant. According to reports, during the period of isolation, the infected person should live alone, stay in his room, close the door, and avoid face-to-face contact with other cohabitants. If you need to leave the room in the presence of other residents, you must correctly wear N95 and KN95 masks, open the door to take things, and avoid face-to-face contact. A chair can be placed at the door of the isolation room, and the transfer items can be placed on the chair to avoid face-to-face contact. The infected person should wear N95 respirator when entering the public area of the home. The infected person and the cohabitant shall keep the serving of individual dishes system, and shall not eat together. If there is no condition for independent use of the toilet, towels, soap and other cleaning supplies should be used separately. A special swab can be prepared. After the infected person uses the toilet, wipe it with alcohol and ventilate the space. It is reported that the infected person will not be infected again in the short term after the antigen turns negative. If the cohabitant turns negative and recovers within one to two weeks, there will be no cross infection or repeated infection during the recovery period. However, if a high-risk infection environment is encountered again after one month of negative transformation, the probability of re infection will increase. The self tested antigen was negative for three consecutive days. Generally, the recovered person will not be infectious and can no longer live in isolation. After finishing living at home, use disinfectants containing effective chlorine or alcohol to disinfect key parts that may have been contaminated by viruses, such as closets, washbasins, trash cans, etc. Toothbrushes and other washing appliances can be replaced with a new set after recovery. Dishes, chopsticks, tableware, and face towels can be heated and disinfected with boiling water. The home environment can be wiped and disinfected with a disinfectant containing 500 mg of effective chlorine per liter. (Outlook New Times)
