After family members are infected with the new coronavirus, they should first arrange for the patient to be treated in a designated hospital, and at the same time cooperate with the epidemic prevention department to isolate the patient in a quarantine point, and carry out nucleic acid tests as scheduled. After the family members are diagnosed with the new coronavirus, they should report to the community and the epidemic prevention department in time, and send the patients to the designated hospitals for treatment of the new coronavirus. As there is direct contact with family members, other family members are also close contacts and are at risk of infection, so family members should go to designated isolation sites in a timely manner to avoid the risk of collective infection. Protect yourself from contact with others before proceeding to isolation. Nucleic acid tests should be performed regularly during isolation to ascertain whether they are infected with the novel coronavirus. Strict disinfection of the residence where the family members are staying should also be carried out. During quarantine, symptoms such as fever should be reported promptly, and if diagnosed, treated promptly.
