Legal basis: Article 41 of the Emergency Regulations on Public Health Emergencies stipulates that the local people's government should do a good job in preventing the outbreak of infectious diseases and floating population in epidemic areas and implement relevant health control measures. From the perspective of risk prevention, administrative organs can only make effective decisions if they do a good job in the health code of prevention and control. It is precisely for the purpose of risk prevention that Chinese people grasp the national epidemic risk information for the first time in emergency management.
