ABSTRACT

In the process of COVID-19 response, problems in China's major epidemic prevention, control system and public health emergency management system have gradually emerged, such as delayed judgment of public health events, concealment and omission of the epidemic, misallocation of medical resources and lag of supplies information. The frequency of public health emergencies increases gradually, which has a serious negative impact on a country's social development and economic growth. Therefore, in order to effectively respond to emergencies in the field of public health, minimize or avoid the harm to the society and the public and improve the government's emergency response capacity, this project proposes a public health emergency warning and prevention and control mechanism based on the "blockchain + big data" technology.
