Study on the mechanism of public service emergency response to public health emergencies ——Take Wuhan as an example

With the frequent occurrence of epidemic diseases such as “SARS”, “H1N1”, “MERS”and“COVID-19”, public health emergencies, which are characterized by large-scale, high risk, strong persistence and high risk, have become more and more obvious threats to the life and health of urban residents and put forward a huge test to the urban public service system. As the first city of COVID-19 human infection, the core of the epidemic spread and the worst-hit area, Wuhan is an ideal case study. Based on the analysis of the epidemic prevention and control actions in the first three months of the outbreak in Wuhan, this paper evaluates the vulnerability of the public service system and facilities in Wuhan. The results show that Wuhan is faced with many problems, such as the failure of community-level public service facilities, the imbalance of public service allocation in the central city, and the significant gap of graded service supply, when dealing with public health emergencies. Further studies found that due to the lack of dynamic early warning mechanism, the decoupling of public service construction from the urbanization process, the difficulty of service turnover and subsidence and other factors, the public service response was delayed. Based on these practical difficulties, this paper puts forward the construction path of the emergency response mechanism for the city level public service system, specifically including the following five key contents: (1) Improving the emergency plan path of the public service system; (2) Establishing the organizational structure of the emergency management system according to the administrative divisions; (3) Building a community-based mobilization system; (4) Establishing the regional joint defense and control interaction mechanism in public health emergencies; (5) Reserving appropriate strategic construction space; (6) Strengthening the emergency infrastructure construction. Finally, based on the path of emergency response mechanism, this paper proposes the corresponding city wide spatio-temporal prevention and control network strategy, so as to provide a reference for the realization of city health and order.
