Stage II: Initial Progress in Containing the Virus

(January 20-February 20, 2020)

The situation became most pressing with the rapid increase in newly confirmed cases in China. As a crucial step to stem the spread of the virus, the Chinese government took the decisive measure to close outbound traffic from Wuhan. This marked the beginning of an all-out battle to protect Wuhan and Hubei from the epidemic.

The CPC Central Committee set up a leading group for novel coronavirus prevention and control and sent the Central Steering Group to Hubei. A joint epidemic prevention and control mechanism and in due course a mechanism to facilitate resumption of work were set up under the State Council. Resources were mobilized nationwide to assist Hubei and Wuhan. Major public health emergency responses were activated across China.

The most comprehensive, stringent and thorough epidemic prevention and control campaign was launched nationwide, and initial progress was made in curbing the spread of the virus (see Chart 5).
