Does Shanghai Anting need to be isolated when returning to Hefei? Now

Shanghai to Hefei must be strictly controlled. You must go to the hotel for seven days and do nucleic acid three or four times in a row.

At present, there is a medium-risk area in Shanghai, and the personnel in the medium-risk area are closed and cannot leave Shanghai. Do people in low-risk areas need 48-hour negative proof of nucleic acid test and other prevention and control requirements when traveling?
