What does Beijing Sixth Tone mean?

The meaning of flow regulation is as follows:

The full name of epidemiology is epidemiological investigation, which is to investigate whether there is the possibility of spreading diseases or the risk of being infected with diseases in the past important period of time. This process is actually like Sherlock Holmes' investigation. We try to find out the transmission chain through clues, find out the close and sub-close people, find out the main reasons for the epidemic of the disease, and take accurate prevention and control measures.

Reason for policy announcement: At present, Omicron has become the main epidemic strain in the world, with fast spread and stronger concealment. In order to further detect and control the epidemic risk in advance, the latest policy for returning to Beijing is: based on the negative certificate of nucleic acid test within 48 hours and the green code of "Beijing Health Treasure", from 0: 00: 65438 on October 22nd, 2022 to the end of March, people returning to Beijing are required to carry out nucleic acid test within 72 hours after arriving in Beijing (commuters continue to follow the existing policy).

"Beijing Health Bao" will be compared through the nucleic acid detection database. If it is not detected on time, a prompt will pop up, which may affect travel and daily life. Please pay attention to the prevention and control reminders and SMS reminders in time, consciously abide by the epidemic prevention regulations, report to the community (village), unit or hotel as soon as you arrive in Beijing, and cooperate with the epidemic prevention work such as nucleic acid detection and health management.
