Those who live and have a history of travel should do the following: (1) Register with your village branch or community as soon as possible and reduce your outings, especially avoiding crowded public places. (2) Perform self-monitoring of health status for 14 consecutive days, twice a day, starting from the time of leaving the area where the disease is endemic. When conditions permit, try to live alone or in a single room with good ventilation, and minimize close contact with family members. (3) If you develop suspicious symptoms of novel coronavirus infection (including fever, cough, sore throat, chest tightness, dyspnea, mild nausea, weakness, slightly poor mental health, nausea, vomiting, diarrhea, headache, panic, conjunctivitis, mild muscle pain in the extremities or lower back, etc.), you should go to a medical institution promptly according to your condition.
