Risk assessment of public health emergencies concerned in the mainland of China, December 2022

  Objective   To assess the risk of public health emergencies occurring in mainland China or possibly imported from outside China in December 2022.

  Methods   Based on various data and departmental notification information on domestic and foreign public health emergencies reports and surveillance of key infectious diseases, the expert consultation method was used and experts from provincial (autonomous regions and municipalities directly under the central government) centers for disease prevention and control were invited to participate in the assessment by video conference.

  Results   The number of reported public health emergencies is expected to rise in December compared to November. China will mainly face the risk of rapid spread and spread of the epidemic and surge in demand for medical services after adjusting preventive and control measures for the new crown pneumonia. A high seasonal influenza outbreak with multiple types and subtypes co-prevalent is expected to occur in the southern and northern provinces this winter and spring. With lower temperatures, the number of non-occupational carbon monoxide poisoning events may increase in December compared to November.

  Conclusions   Special attention is given to novel coronavirus pneumonia, and general attention is given to seasonal influenza and nonoccupational carbon monoxide poisoning.
