"When doing flow adjustment work, we have to find out the detailed trajectory of each case within 14 days. The workload is huge, but every minute must be raced against. Ruili's particularity has increased the difficulty of flow adjustment work." Recently, Ruili City, Yunnan Province Liu Yonghua, deputy secretary of the Party branch of the Centers for Disease Control and Prevention, and leader of the circulation team, unveiled the mystery of the circulation work to the China News Agency reporters.
"Flow regulation" means epidemiological investigation, which is the key to epidemic control and an important basis for scientific decision-making.
Liu Yonghua has been engaged in the prevention and control of infectious diseases for a long time. After the outbreak of the new crown pneumonia in early 2020, he began to participate in the flow adjustment work and has rich experience.
"The main purpose of the circulation is to find out the source and transmission route of the virus, and the other is to determine the close contacts and sub-close contacts, and take measures to isolate them." Liu Yonghua introduced, in the epidemic, the circulation Personnel need to take risks to investigate and analyze cases and epidemic areas. They must not ignore any suspicious information. They must neither miss the judgment nor judge it well.
"Therefore, intermediary personnel are often referred to as the'Holmes' on the front line of epidemic prevention and control."
"Many people think that the flow is very mysterious. In fact, the key to the flow is one word-'fine'." Liu Yonghua said that in the face of a case, the flow regulators must be patient and ask every detail in their lives. , To help them restore the complete trajectory of their actions within 14 days.
"In fact, it is difficult for most people to recall all the details of their 14 days. At this time, we will guide the cases to use the records in their mobile phones to recall their actions." Liu Yonghua said.
Since 2020, under the severe import pressure of overseas epidemics, Ruili, which is located on the border of China and Myanmar, has experienced four epidemics of "9.12", "11.09", "3.29" and "7.04".
Ruili is a border county and city where many ethnic groups gather. At the same time, some Burmese people work and live there.
In the flow adjustment work, how to maintain smooth communication has become a difficult problem.
Liu Yonghua said, “When we encounter difficulties in communication, we will bring translators, but the bigger problem is that some Burmese cases cannot describe the exact name of the place where they went out. If there is really no way, we will arrange negative pressure. The ambulance, carrying the case of Burmese nationality, led the way, and the intermediary personnel followed to find out the trajectory of the case."
Among the several epidemics in Ruili, Liu Yonghua felt the most pressured by the "March 29" epidemic.
"At that time, there were many cases, and the intermediary personnel were fighting continuously, from early morning to dark, and from late night to dawn. I remember very clearly that I only slept for 3 hours in 5 days."
In July 2021, Ruili suffered from the "7·04" epidemic caused by the highly contagious Delta strain. However, Liu Yonghua admitted that he was not panicked at the time. "When the Delta appeared in Guangzhou, China in May, Ruili The epidemic prevention and control strategy has been adjusted in accordance with its characteristics, and the general public has also paid more attention to personal protection."
At work, some people have also encountered difficulties in refusing to cooperate with the flow because they do not want to disclose their personal information.
"But only true and effective information on the circulation can scientifically assess the epidemic situation and take correct prevention and control measures. The general public must trust and cooperate with the circulation personnel!" Liu Yonghua appealed.
In the process of fighting the epidemic, Ruili's circulation ability has been continuously improved.
"With the support of intermediary personnel from all over the country, the intermediation work has been carried out more quickly and more accurately." Liu Yonghua explained, "For example, after determining the trajectory of a case, we will retrieve surveillance videos of relevant locations based on the protection status of the case at the time. , The length of exposure, etc., to analyze the spread of the epidemic. The prevention and control measures based on the results of the flow adjustment are also more accurate and effective."
At present, the epidemic is still continuing to spread outside the country. Since October, there have been multiple local cases in Ruili City.
However, Liu Yonghua is full of confidence in realizing the epidemic prevention goal of "dynamic zeroing". "As Ruili accelerates the construction of a three-dimensional border prevention and control system and vaccination, I believe that'dynamic zeroing' will definitely be achieved." (End)
