The functions and responsibilities of China Center for Disease Control and Prevention are clearly stated in its official website. The main functions and responsibilities are disease prevention and control, emergency treatment of public health emergencies, formulation of public health technical plans and guidelines, etc. For example, in response to the COVID-19 epidemic, the Centers for Disease Control and Prevention provided several versions of the guidelines. And what are the functions and responsibilities of the National Bureau of Disease Control and Prevention? According to relevant statements, the National Bureau of Disease Control and Prevention is responsible for formulating policies for the prevention and control of infectious diseases and public health supervision, guiding the construction of disease control system, planning and guiding the construction of epidemic monitoring and early warning system, and so on.

Obviously, from the functions and responsibilities of China Center for Disease Control and Prevention and the National Bureau for Disease Control and Prevention, we can clearly see the specific differences between these two national institutions. Although the common mission of these two institutions is disease prevention and control, relatively speaking, the functions of China Center for Disease Control and Prevention are more specific, while the functions of National Bureau for Disease Control and Prevention are more macro, with the former focusing on details and the latter focusing on the overall situation. Specific to the expression of functions, CDC formulated "programs" and "guidelines" and CDC formulated "policies". Obviously, "policy" is greater than "plan".
