Now the epidemic prevention and control is in a stalemate, and the situation in Hubei and Wuhan is still very serious. Wuhan is where the outbreak first started and the outbreak is more permanent and serious than elsewhere. The proportion of imported cases in other provinces of the country is gradually decreasing and individual places have gradually bottomed out. Hubei Province is generally in an epidemic phase with local outbreaks, while Wuhan is still in an outbreak epidemic phase and new cases are still at a high level. In addition, compared with the importing places, the bottom number of infected people in Wuhan has not been fully mapped, and the scale of spread and proliferation is not predicted by more accurate estimates. According to the relevant agencies projections, the base of potential infected in Wuhan is relatively large.
