For precautions during the coronavirus epidemic period: first of all, to prevent the spread of the new coronavirus, usually go out as little as possible, keep a certain distance from human contact, avoid droplet transmission and close contact transmission, wear a good mask, usually do diligent hand washing, ventilation and home disinfection. If you have been to an infected area or have been in contact with an infected patient, you must be isolated for 14 days and be closely observed for symptoms during the isolation period, and have a nucleic acid test done. If there are no symptoms within 14 days and the nucleic acid test is negative, the quarantine can be lifted. Patients in the incubation period are highly contagious even if they have no symptoms, so they should be isolated for observation. For people who develop fever at home and are suspected of novel coronavirus infection or have an epidemiological history, they must be proactively reported to the community and escorted to a designated hospital by isolation to be screened for coronavirus infection.
