Is the SMS of big data epidemic based on mobile phone or number owner?

Big data epidemic SMS is sent according to the mobile phone number.

The COVID-19 Epidemic Prevention and Control Command was informed that sending big data epidemic information according to the mobile phone number is a spatio-temporal phenomenon. According to the relevant person in charge, the city is currently carrying out further flow adjustment work, using big data, "internet plus" and other technical means to screen relevant personnel. If the citizen's phone number and the number of confirmed cases stay in the same time-space grid (the range is 800 meters ×800 meters) for a period of time, they will receive an epidemic prevention and control reminder message.

"The space-time grid is fixed. If the space-time grid area where the confirmed case number is located is larger than the Transit Shopping Plaza, in addition to the people in the mall, the surrounding activists will also receive relevant reminders. " The person in charge said that big data only plays the role of screening and reminding. People don't have to panic when receiving information. They can check the activity track in time or report it in time according to the content of SMS reminder.

After receiving the message, don't panic, please do this:

1, if you have ever lived in a middle-high risk area, especially overlapping with the activity track of people with positive nucleic acid test, please isolate at home first, report to the local community (village) or county-level CDC immediately, and cooperate with relevant epidemic control measures.

2. If you come from a city in a medium-high risk area, but you have never been in a medium-high risk area, and there is no overlap with the activity track of people with positive nucleic acid testing, please do nucleic acid testing as soon as possible under the condition of personal protection (see Changsha Publishing House and Changsha CDC for details on the sampling points of nucleic acid testing in COVID-19), and pay attention to personal protection and health monitoring in daily life.

Municipal CDC will not require citizens to transfer money, remit money or provide bank card passwords and verification codes in any form.

The general public should be vigilant, don't trust calls and text messages of unknown origin, and don't click on links of unknown origin.
