How does the epidemic code locate where you want to go?

The epidemic code tracks your location according to the location of the calling card, but it can only track the big location.

From 20: 30 on 202118, the city name of the medium-high risk area is no longer marked in red on the travel card, but is marked in brackets after the city name. Precautions are only used as travel tips and have nothing to do with health status.

On March 30th, the national government service platform "Epidemic Prevention Health Code" has integrated the relevant information of "Communication Big Data Travel Card", which can show whether the user has been to medium and high risk areas and other travel information in the health code, helping the health code to be "one code pass". ?

On August 5th, the joint prevention and control mechanism of the State Council held a press conference, and the "communication itinerary card" provided more than 654.38+0.2 billion times of inquiry service, which became an important means to prevent and control the epidemic in various places.

Users can directly search for "health code" in Baidu App, and the search results can simultaneously present the health code of the user's location and the "epidemic prevention and health information code" of the national government service platform. The information column "Traffic Big Data Travel Card" is integrated under "Health Code" on the "Epidemic Prevention Health Information Code" page, which can show whether the user has been to medium and high risk areas and other travel information. ?
