Many people are concerned that the return rush will cause another outbreak of the epidemic. First of all, since New Coronary Pneumonia has an incubation period, after the Chinese New Year and extended holidays, most of the infected people have basically developed the disease. In addition, strict check points have now been set up in various cities, and airplanes, trains and other means of transportation also conduct strict temperature screening. Those with fever symptoms must be sent to fever clinics at designated hospitals for nucleic acid testing and chest CT examinations, and those who meet the conditions for isolation are isolated and observed. Furthermore, after the preliminary publicity and science, the masses have done a good job of wearing masks and other personal protection, so a higher peak is not predicted to occur again after the return trip. On the way back, it is important to strengthen personal health and hygiene protection, wear masks and cooperate with staff to do a good job in temperature measurement and other related prevention and control work.
