Generally speaking, COVID-19 will not directly transmit the virus from infected people to healthy people. In COVID-19, droplets are usually used as carriers and adsorbed on the surface of tiny droplets. When the patient coughs or sneezes, the droplets are discharged, and the virus is adsorbed on the particles and discharged with the droplets. Droplets are generally small, at 1-5 microns, and the propagation distance should be 1-2 meters. Healthy people are infected when they inhale droplets adsorbed by the virus. In the past two years or so, it has not been found that flying flocs can adsorb viruses, and so far there has been no report on the infection caused by flying flocs.
How should family members and neighbors take precautions before the positive infection is transported to the isolation point?
For some infected people who have just been diagnosed as positive and can't go to the isolation point, first, to reduce the risk of family transmission, we must have a separate bedroom, preferably a separate bathroom, and we can't eat with our families or communicate with them; The second is to reduce the risk of infection to neighbors or community residents. Families with positive infections should disinfect the living room, bathroom and other environments in time, resolutely put an end to door-to-door phenomenon, and resolutely put an end to activities and exchanges with people in the community.
For residents living in the same building or community, the whole building and community belong to the closed management stage for a period of time after the patients are transferred, and all residents are isolated at home and abide by the rules of staying indoors. During containment management and health monitoring, everyone should pay attention to the changes of their physical condition, whether there are symptoms such as itchy throat, sore throat, cough and fever. And self-test by antigen testing. If you have suspected symptoms or positive antigen detection and screening, you should contact the local epidemic prevention department in time for timely disposal.
