Dynamic zeroing is more flexible than static zeroing, but at the same time the difficulty will rise. In terms of the current situation of the epidemic in Shanghai, the best solution to fight the epidemic in Shanghai should start from the following three aspects.
To delineate high-risk and medium-risk areas. This is one of the management measures implemented in many provinces across the country. Once the number of confirmed or asymptomatic cases has occurred, high-risk and medium-risk areas should be divided according to different regions and strict control measures should be implemented in these areas. The isolation of people in high-risk and medium-risk areas within certain boundaries ensures the free movement of people in low-risk areas. One of the best solutions is to reduce the high-risk and medium-risk areas to low-risk so that the whole of Shanghai becomes low-risk.
Make sure that no one goes out of Shanghai unless it is necessary. As the saying goes, in the face of an epidemic, no country can survive alone, and this also applies to the domestic situation in the face of the epidemic, no province can survive alone, Shanghai's anti-epidemic program and the extent of the direct impact on other provinces of some of the pressure of the defense policy. So Shanghai not only in the internal fight against the epidemic at the same time, but also to ensure that the Shanghai people do not go out, if necessary out of Shanghai must have 24 hours of nucleic acid proof and 24 hours of antigenic nucleic acid test report, so as to maximize the other provinces to ensure the degree of security.
There must be sufficient medical supplies and abundant medical personnel. Shanghai, as an international first-tier metropolis with more than 20 million people living in it, is very slow to rely only on local health care workers for nucleic acid testing, so more than 30,000 health care workers across the country are now departing for Shanghai to support nucleic acid testing in the city. Accelerating the speed of nucleic acid testing is the only way to identify potential risks and some asymptomatic people in the shortest possible time, and to reduce all risk areas through nucleic acid testing.
