What does the health code with * mean?

An * (asterisk) after the city name indicates that there are medium-risk or high-risk areas in the city at present, but it doesn't mean that you have actually been to these medium-high risk areas. "Passing by" means staying in a place for more than 4 hours. When you open the itinerary code with your mobile phone, the system will automatically record it as passing by or visiting.

(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.

The "Communication Big Data Travel Card" service was jointly launched by China Information and Communication Research Institute of the Ministry of Industry and Information Technology and three major telecom operators. Using the communication big data of China Telecom, China Mobile and China Unicom, it provides travel inquiry service for 654.38+06 billion mobile phone users nationwide.
