Usually not. According to the latest unified requirements of the prevention and control department, after big data analysis and epidemiological investigation, we will also send reminder messages to citizens who have lived in areas where there may be risks and have intersection with risk personnel. They will get the 1 health code on 1 and the third day from the date of risk determination and investigation, respectively. After being converted into yellow code twice, they will need 1 nucleic acid detection to be transferred. You can go to the nearby yellow code nucleic acid detection point to complete the detection.

Tip: If the test result of 1 is negative, the health code will change to "green code" for a short time, and then to "yellow code" again, prompting the public to conduct the second test as required. If the results of two nucleic acid tests are negative, the health code will be officially changed to "green code".
