When can health code gray turn green?

The health code will turn gray to green under the following conditions:

According to the situation, it is generally determined that nucleic acid detection can be turned into green code after the specified time and frequency are completed. For example, some places with gray health codes need to complete nucleic acid sampling. After the sampling is completed, the gray code will automatically turn green in about half an hour. This is to remind the general public to do nucleic acid as soon as possible and give the health code to Gray code. Generally speaking, when the health code changes color, you will receive a short message signed by a city CDC to remind everyone to actively fulfill their personal epidemic prevention and control responsibilities and actively cooperate with nucleic acid testing and sampling. The SMS will also remind you that the health codes of those who have not been tested for nucleic acid will be managed in a gray code in the pilot, and the gray code personnel will be strictly restricted from entering crowded public places (except medical and health institutions), and it is strictly forbidden to take public transportation and online car rides; After the sampling is completed, the gray code can be automatically converted into green code, and transcoding operation can be carried out according to the SMS prompt.
