4.1. Discussion of Results
Since the beginning of the COVID-19 pandemic, public health decision-makers have been called on to identify responses that are appropriate in intensity, duration, and scope , and the corresponding emergency prevention and control measures taken by the Chinese government have played a great role. Compared with the response to public health emergencies in the past, emergency prevention has always been the key link to prevent the epidemic from worsening and reduce the loss of the epidemic. By comparing the cost of treatment during a large outbreak of hepatitis A with that of prevention and control and prevention in advance, it was found that the cost of the latter was much lower than the former . It should be noted that the results of this study showed that since the questionnaire was issued at the peak of the epidemic in China, the public had a poor risk perception on novel Coronavirus in the early stage of the epidemic and had negative emotions on the prevention and control of the epidemic at the early stage, so the public generally did not accept the government measures at the early stage of the epidemic. Moreover, theoretical prevention and control measures are prone to deviation when they are implemented in reality. Ajay and Bhargavi  believe that although in theory the advance prevention before the occurrence of an emergency is more beneficial, due to the impact of regional social concepts, cultural traditions and other factors, the advance prevention is difficult to implement in practice, resulting in the inefficiency of prevention. However, with the development of the epidemic, public acceptance has gradually increased, which proves that the prevention and control measures taken by China are indeed positive and effective.
To contain COVID-19, full cooperation between the government and the public is essential. China has made comprehensive prevention and control measures from the perspectives of social isolation, traffic control, screening and testing, dynamic monitoring, diagnosis and treatment, resource allocation and material support. This study examines the effectiveness of these measures from the perspective of the public. This study, according to the construction of specialized hospital strengthen population medical treatment work measures such as public acceptance, diagnosis and treatment are one of the most important aspects of dealing with emergent public health events, Shwiff Katie and Aaron  showed that treating infectious diseases population can bring a broader economic benefits to the nation. Also, according to all kinds of people to traffic control measures such as high, traffic control measures such a real can effectively inhibit the spread of expansion, Jin, Lu, Ding, Chen and Peng's study of quantitative evaluation of the Wuhan city traffic control and centralized quarantine measures to control the action of COVID-19 outbreak, WuHan traffic control and centralized quarantine measures for disease control have a pretty good effect can provide a reference for other countries the epidemic prevention and control. At present, China has seen a significant reduction in the epidemic, while other severely affected countries have not seen any improvement. The implementation of measures such as traffic control and centralized isolation has become an important consideration for other countries to curb the epidemic.
The main purpose of this study is to design a questionnaire on public acceptance of government emergency prevention and control measures for COVID-19 that can be used to investigate public health emergencies, to investigate whether the emergency prevention and control measures taken by local governments of COVID-19 are timely, effective, and accepted and adopted by the public. The results of data analysis were used to explore whether there were significant differences in the acceptance of different groups to various aspects of government measures. This research data shows that, with the development of the outbreak, the public new crown outbreak risk perception is increased. The blockaded city, closed community management, extension work extension of school and take clear implementation of network teachings such as policy, our country's resistance to disease progress and orderly, increased acceptance of public emergency prevention and control measures to the government rate increases gradually. The timeliness and effectiveness of the government's emergency prevention and control measures have a direct impact on the development trend of public health events and the emergence and solution of livelihood issues. However, since the outbreak of the epidemic, China has constantly been groping in the development of the epidemic and has found the most effective means of prevention and control. In addition, there are differences among groups of different genders, ages, regions and occupations in terms of the level of education received, the degree of the grasp of real-time information on the Internet and the degree of attention paid to national health security. This difference is reflected in the public's acceptance of emergency measures for epidemic prevention and control during the epidemic period. People of different ages, regions and occupations have different receptivity to the measures, so they have different attitudes towards the development of the epidemic under the overall environment of weak public perception of the risk of the epidemic. At this time, relevant departments in different regions should take effective and reasonable measures to cope with the development of the epidemic according to the characteristics and specific conditions of their jurisdiction.
4.2. Research contributions
As an investigation and study during the COVID-19 epidemic, this study pays close attention to the development of the epidemic and analyzes the implementation of epidemic prevention and control measures from the perspective of the public, which is of profound significance to the prevention and control of the epidemic.
This study focus on one of the most important factors affecting the effective control of the epidemic: the public acceptance to the epidemic prevention measures, design the questionnaire from acceptance directions, explore the differences in the public's acceptance of the epidemic prevention measures adopted in China by different demographic characteristics, to further explore how to reasonably deal with public health emergencies prevention and control measures.
4.3. Lack of research
Due to some limitations, this study still has some limitations in terms of research methods and research contents. This part will summarize and provide a reference for future researchers.
1) The questionnaire content of this study only considers common demographic characteristics such as gender, age and educational level. It ignores other demographic characteristics, such as whether they have experienced (participated in emergency protection) other public health events, etc. In the future, these factors can be added, so that specific measures can be better proposed for the government to issue recommendations, the results will be more accurate and detailed.
2) The questionnaire data obtained in this study are concentrated in different regions, so in future studies, the sample size can be increased to improve the diversity of samples and the proportion of average sample distribution.
