Analysis of COVID-19 epidemic data in Chinese mainland

COVID-19 is the most extensive global pandemic affecting mankind in the past century, and it is a serious crisis and a severe test for the whole world. Human life security and health are facing a major threat. The aim of this study was to analyze the epidemic situation in Chinese mainland in November 2022. Based on the data given on the official website of the National Health and Wellness Commission of China, the data on the outbreak of infected persons during the period from 0:00 a.m. on November 1, 2022, to 24:00 a.m. on November 30, 2022, were quantitatively analyzed by means of statistical analyses. The overall epidemic trend graph we plotted through EXCEL, and descriptive statistics were analyzed according to the data on the spread of the epidemic, deaths and cures. The results showed that the data for the whole month of November showed a slow and almost linear increase in the number of deaths, and the number of cures continued to increase at a higher rate than the number of deaths. The average mortality rate was 1.85%, with a minimum of 1.61% on November 30, while the cure rate had a maximum of 96.13% and a minimum of 86.84%. The stabilization of the cure rate and the low fluctuation of the mortality rate indicate that the Government's emergency response has been effective. China established a national emergency management system after the SARS outbreak in 2003, emphasizing hierarchical responsibility and territorial-based public health emergency management. In order to improve public health services, it is necessary to strengthen the planning of public health emergencies, improve the capacity of medical institutions and health administrative departments, increase resource investment and personnel training, and establish an incentive system for medical personnel. It is also crucial to strengthen the rule of law in public health, raise public health awareness, and enhance international exchanges and cooperation. These measures will help improve society's ability to respond to public health incidents and safeguard the health and safety of citizens.
