2.1. Data Source

The data are from the epidemic distribution of COVID-19 in China from 0:00 on January 24 to 24:00 on February 23, 2020 released by the National Health Commission, and the information of the official emergency response measures taken by the Chinese government website. The time period is 1 month, i.e. 31 days.

2.2. Analysis Method

The paper selects the indexes such as confirmed, suspected, deaths, and cured population and uses EXCEL to draw the national total change trend chart of COVID-19, and Statistical Product and Service Solutions (SPSS) to calculate the fluctuation range and mean of mortality and cure rate, and to analyze the spread of new coronavirus pneumonia. Through qualitative analysis of the emergency management response measures adopted by various administrative departments and provinces and regions in China, this paper explores China’s public health emergency management framework and capacity to cope with the development of COVID-19 epidemic, so as to further study the existing weakness and propose countermeasures and suggestions.

3.1. The Trend of the Total Amount of COVID-19 Diffusion

In Figure 1, the data shows the increase of the number of confirmed patients (increase), the cumulative number of confirmed patients (total), and the number of suspected infected patients (suspect) in this 1 month. The increased cases in this paper refer to the newly increased confirmed cases compared with the previous day. The data in Figure 2 show the cumulative number of deaths (death) and discharges (cured). On January 24, there were 1287 confirmed cases, and on February 23, the total number of confirmed cases was 77,150. The number of confirmed cases (red) showed a linear growth trend, which tended to increase first and then decrease. On February 12, the number of people increased dramatically, from 44,653 on February 11 to 59,804 (Figure 1). It broke through 70,000 for the first time on February 16 and has since slowed. The suspected curve (yellow) and the increase curve (blue) both showed an inverted V-shaped trend. The peak of the suspected curve appeared on February 8, and the maximum value was 28,942. At this time, it was exactly 15 days away from January 23, which was in line with the prediction of the incubation period of 14 days. Since then, the suspected values have fallen, indicating that the “stock” has been reduced. On February 12, the increase curve peaked with a maximum value of 15,152, mainly due to the revision of the criteria for confirmation on February 12, resulting in the number of new confirmed cases exceeding 10,000 on that day. Since then, the number of new cases has dropped significantly and emergency management interventions have gradually come into play. This shows that, due to the long incubation period of the virus, the strong infectivity, and relatively insidious, the emergency response will not appear immediately after the start of the effect, but after a certain response cycle.

3.2. Trends in Mortality and Cure Rates

The number of deaths increases slowly, in a nearly linear trend. The number of cured people increases day-by-day, which is similar to the exponential growth trend (Figure 2). The growth rate of the number of people cured was significantly higher than that of the number of died people. In this paper, the specific mortality and cure rate were obtained by dividing the number of deaths and cured cases by the cumulative number of confirmed cases, and descriptive statistical analysis of the mortality and cure rate was conducted by SPSS software (SPSS Inc., Chicago, IL). The results showed that during the 31-day study period, the mortality rate fluctuated between 2.0% and 3.4%, with a minimum of 2.01% on February 4 and 5 and a maximum of 3.36% on February 23. The average cure rate was 10.03%, and the minimum value 1.33% appeared on January 27, and the maximum value 32.05% appeared on February 23. Since February 13, the cure rate has been greater than 10%, and since February 19, the cure rate has been greater than 20%. The significant increase of cure rate and small fluctuation of death rate indicate that the government’s emergency intervention measures are effective and that the emergency management system plays an important role.

3.3. Public Health Emergency Management Framework and Epidemic Response Measures

China’s public health emergency management system is divided into horizontal and vertical system dimensions. In terms of horizontal emergency management, the state council is the highest administrative leading department, and led by the National Health Commission, the joint prevention and control mechanism of public health emergencies was firstly composed of 32 ministries and commissions of the state council (Figure 3). The 32 units included National Health Commission, National Development and Perform Commission, Ministry of Finance, Ministry of Science and Technology, Ministry of Culture and Tourism, Ministry of Civil Affairs, Ministry of Public Security, Ministry of Justice, Ministry of Transport, Ministry of Industry and Information Technology, Ministry of Education, Ministry of Agriculture and Rural Affairs, Ministry of Ecology and Environment, National Audit Office, Human Resources Security Department, Ministry of Foreign Affairs, Ministry of Commerce, Ministry of State Security, Ministry of Natural Resources, People’s Bank of China, Ministry of National Defense, Ministry of Housing and Urban-Rural Development, Ministry of Water Resources, Ministry of Emergency Management, Ministry of Veterans Affairs, The General Administration of Customs, National Radio and Television Administration, General Administration of Sport, Healthcare Security Administration, Ethnic Affairs Commission, State Taxation Administration, and General Administration of Market Regulation. Multi-sectoral and trans-regional cooperation mechanism is adopted to make clear division of labor and form joint forces, and to establish a joint defense and control mechanism of “vertically to the end and horizontally to the edge” [3]. On January 24, solstice on February 22, 32 national ministries and commissions successively issued more than 70 response measures and standard requirements on the prevention and control of the new coronavirus pneumonia. In particular, during the period from January 24 to January 31, 25 ministries and commissions issued more than 30 epidemic prevention and control notices. It covered many emergency response measures including epidemic monitoring, emergency resources supply, daily supplies supply, traffic control regulations, financial subsidies allocation, social order stability, human resource relationship guarantee, medical insurance reimbursement, and drug payment preferential treatment.

Public health emergency management framework for COVID-19.

Vertical emergency response system refers to the four-level vertical management system of “state–province–city–county”, specifically speaking, the national public health emergency command composed of the state council, which successively directs the emergency management mode of the provincial public health emergency command, prefecture-level government, and county-level government (Figure 3) [4]. General Emergency Plan for National Public Emergencies of China and Contingency Plan for National Work Safety Accidents and Disasters of China classify accident response into four levels, namely, Grade I accident (level I response), Grade II accident (level II response), Grade III accident (level III response), and Grade IV accident (level IV response). The grade I accident indicates that the cumulative number of confirmed cases is very large, and the epidemic situation is very serious. By analogy, level IV indicates a cumulative number of confirmed fewer people [5]. According to the unified decision, deployment and command of the state council, 31 provinces, municipalities directly under the central government and autonomous regions in China successively launched a first-level (level I) response to the new coronavirus pneumonia epidemic from January 23 to January 29, and organized and coordinated the emergency response work within their respective administrative regions. For example, Beijing municipality issued a specific notice and proposal on strengthening the prevention and control of pneumonia caused by new coronavirus. Heilongjiang province set up aid medical team to Wuhan. Hebei province put on the drugs and medical services used by confirmed patients to the regional essential medicine list and local health insurance system. Over 15 provinces including Shandong, Anhui, Guangxi, Hainan, and Tianjin ensure the supply of daily necessities and stabilize the prices of food and epidemic prevention supplies. Zhejiang, Jiangsu and other provinces carry out online government office services. Tianjin and Jiangsu provinces promptly allocate funds for epidemic prevention subsidies.

In addition, under the overall deployment and command of the state council, all provinces carry out trans-regional cooperation. On February 10, the National Health Commission pooled high-quality resources to establish a working mechanism for interprovincial counterpart to support the medical treatment of COVID-19 pneumonia in cities other than Wuhan in Hubei province. In addition to Wuhan, 19 provinces provided support to 16 cities with severe epidemic conditions in Hubei province, and gave full support to Hubei province to ensure patients’ treatment and safeguard, so as to maintain people’s safety and health.

4.1. Improve the Public Health Emergency Management System

China needs to continue to carry out top-level design for building institutions and mechanisms, improve the monitoring system for public health emergencies, and achieve networked and accurate management. China should improve the emergency response mechanism for major outbreaks, establish a centralized, unified and efficient leadership and command system, and improve our ability to respond to major public health emergencies [7]. China should strengthen cross-provincial, cross-regional and -departmental communication, and collaboration mechanisms.

4.2. Optimize the Public Health Service System

China should strengthen the development of a contingency plan system for public health emergencies, formulate contingency plans by category, and specify and standardize the specific contents of such plans. China should focus on improving the ability of medical institutions and public health administrative departments at all levels to respond to and manage public health emergencies. China should increase investment in medical and health resources, strengthen the public health workforce and personnel training, and improve the personnel structure. China should establish an evaluation and incentive system for medical personnel and improve their remuneration.

4.3. Strengthen the Rule of Law in Public Health

China should repair the wildlife protection act. The wild animals carrying the virus are included in the fasting list, the areas of endangered wild animals are strictly protected, and the punishments for those who eat and sell wild animals are clearly defined [8]. China should strengthen publicity of the laws on the prevention and treatment of infectious diseases enacted in China and comprehensively improves our ability to prevent and control infectious diseases in accordance with the law.

4.4. Raise Public Health Awareness

China should intensify efforts to publicize the prevention and treatment of infectious diseases, and conduct popular science education to the general public through the preparation of publicity manuals, popular science books, new online media and other forms. In the community, experts and doctors of infectious diseases will be invited to give training lectures on popular science, so that the public can learn basic knowledge and ideas of epidemic prevention and have basic skills to deal with sudden infectious diseases.

4.5. Facilitate International Exchanges and Cooperation

China should learn from the advanced public health emergency management system across the world, such as World Health Organization, including emergency management organization system, operation mode, early warning and monitoring, scientific research and experiment, and civic education. China should actively participate in international academic exchanges on epidemic prevention and control, work closely with counterparts around the world to share research results, and fight against infectious disease.
