Generally speaking, yellow code personnel can turn to green code as long as they finish two tests within three days, that is, they can conduct two nucleic acid tests within three days, and the interval between two nucleic acid tests must be more than 24 hours. But at this time, it should be noted that if the test result of 1 is negative, the health code will be temporarily changed to "green code" and then changed to "yellow code" again, prompting them to carry out the second test as required.
If the second nucleic acid test is not carried out, the health code will naturally turn into a yellow code. Secondly, if your health code changes from yellow to green, but you have been to a middle-high risk area or have been judged as a space-time partner, then your health code will turn yellow again. Therefore, residents are advised to report to the local community immediately after the health code turns yellow, and then decode it as required.
Travel code asterisks can disappear in two ways.
(1)/kloc-0 disappeared after 4 days. This time limit is based on the user's own time and has nothing to do with the risk area. If the travel card asterisk still exists after 14 days, you can call the relevant communication service provider of the communication travel card to adjust it.
(2) After the risk level of the risk area is modulated to low risk, the asterisk will disappear by itself.
