Why does the traffic police remind us that the intersection of time and space does not exist?

Answer: "Time-space crossing" means that the mobile phone number and the mobile phone number of COVID-19 positive cases stay in the same signal grid (usually 800 m× 800 m) for more than a certain time. As long as there is an intersection with the trajectory of positive cases, whether it is a physical pass or a cell phone signal from the same communication base station, it may be considered as a "time-space intersection".

There is a reasonable error in capturing the information of "intersection of time and space" through big data. In order to protect the health and life safety of the general public to the maximum extent and block the spread of the epidemic in the shortest time, a short message will be sent to the mobile phone of "time and space convergence" to remind the public to carry out nucleic acid testing and health monitoring.

With the in-depth development of epidemiological investigation, the scope of "time-space intersection" will be gradually adjusted, and reminder messages will be sent at different time periods, and residents living near the trajectory of positive cases will also be reminded by SMS. I hope the public will understand and cooperate with the epidemic prevention and control work.

Q: Why are some residential areas and public places not mentioned in the notification temporarily controlled in the urban area, except that the locations involved in the trajectory of the notified positive cases have been controlled?

A: According to the requirements of epidemic prevention and control, in order to minimize the risk of epidemic spread, in addition to taking control measures for the areas involved in the trajectory of positive cases, all districts will temporarily control the areas involved by close contacts of positive cases in light of the current situation to further investigate the epidemic risk. Recently, some residential areas and public places in our city have been temporarily controlled, which belongs to the above situation.

It should be noted that some areas are temporarily controlled, which does not mean that there are positive cases in this area, but that close contacts are being investigated. Please don't panic, give understanding and cooperation, and do a good job in nucleic acid detection, family health monitoring, centralized isolation observation and other epidemic prevention and control measures according to community arrangements.

Q: I received the message of "crossing time and space", but the health code didn't turn yellow. Can I take public transportation?

A: After receiving the message of "crossing time and space", please carry out nucleic acid detection and health monitoring according to the prompt. In the meantime, it is recommended not to take public transport to reduce crowd gathering activities.

If the health code is given a "yellow code", you can't take public transport. Starting from August 22nd, public places such as Kunming Airport, railway station and passenger station, as well as public transport vehicles such as taxis, internet taxis, buses and subways will strengthen the "two yards" inspection of passing passengers.

Q: Why are some nucleic acid testing stations free and some charge?

A: There will be certain costs and expenses for nucleic acid testing. According to the relevant provisions of the state, qualified medical institutions can provide nucleic acid testing to citizens and charge a certain fee.

During the emergency response period of epidemic prevention and control, in order to facilitate people's daily nucleic acid detection and solidly promote policies and measures to benefit the people and the people, according to the needs of epidemic prevention and control, since April 2022, Kunming has set up some free nucleic acid detection points in the form of financial commitment at the city and county levels, and the current free detection time has been extended to August 3 1.

In order to further facilitate people to find nucleic acid detection points, Kunming has formulated a map of free nucleic acid detection points, including free nucleic acid detection points, paid nucleic acid detection points in medical institutions, and 24-hour detection points, so as to facilitate citizens to choose flexibly.
