How long will it take to get a short message from Nanjing CDC to turn yellow?

Don't worry after Jiangsu health code becomes yellow code. Be sure to calmly understand the relevant issues. Although the yellow code appears, it doesn't mean that you are infected with COVID-19 virus. As long as the nucleic acid detection is completed according to the regulations, the yellow code can be changed back to the green code. According to the official response, you have completed the "two tests in three days", that is, you have done two nucleic acid tests. The interval between the two tests is more than 72 hours, and the results are negative. You can remove the yellow code. Therefore, after the nucleic acid test, your health code will change back to the green code, and travel will naturally not be restricted.
