After a case of novel coronavirus pneumonia is diagnosed, it will be treated in medical isolation at a designated hospital. Close contacts will be isolated and medically observed in accordance with the relevant requirements, and the homes of confirmed cases and common areas of the community will be cleaned and disinfected. As a general resident of the community, there is no need to overly panic, just continue to do a good job of personal protection. Ventilate your home, keep it clean and sanitary, and avoid close contact with patients with fever and cough as much as possible. Avoid crowded places and confined spaces as much as possible, and wear a mask if you have to go. Pay close attention to symptoms such as fever and cough, and seek medical attention when such symptoms occur.
