At present, the epidemic prevention and control has entered a normal state, and the situation of “import of external prevention and rebound of internal prevention” remains grim. The general public should have a deep understanding of the complexity and uncertainty of COVID-19 epidemic prevention and control, and always stay focused on epidemic prevention and control to overcome paralysis and fluke mentality. Everyone is the primary responsibility for his or her own health. We should actively cooperate with the implementation of epidemic prevention and control measures. People should keep personal protection, wear masks scientifically, go out carefully, do not gather, wash hands frequently, ventilate frequently, use chopsticks, and maintain a safe social distance; Purchasing and processing imported cold chain food should do a good job of personal protection according to the specification requirements; In case of fever, cough and other abnormal conditions, you should take good personal protection and go to the fever clinic of the nearest medical institution for medical treatment in time. Try to avoid taking public transportation for medical treatment.
