(Fighting New Crown Pneumonia) Record of "Evil" in Wuhan War: Detective "Vicious" Strangles the "Throat" of the Virus from the Source

China News Agency, Wuhan, March 5th: The "epidemic" of Wuhan war: arrested the "vicious" from the source to choke the virus "throat"

In the front line of the epidemic, epidemiological investigators (hereinafter referred to as flow officers) are like scouts, cutting information and splicing together pieces of information to find the source of infection as soon as possible, find out the transmission chain, and win time to stop the spread of the epidemic. Tong Yeqing, deputy director of the Institute of Infectious Disease Prevention and Control of Hubei Provincial Center for Disease Control and Prevention, recently accepted an exclusive interview with a reporter from China News Agency, telling how epidemiological investigations can be used to capture the real "fierce".

If it's one minute late, the virus will "get away" for another minute

Tong Yeqing introduced that from receiving the transfer notification, the transfer officer entered a high-speed working state. Go to the ward for the first time to inquire about cases, issue an epidemiological investigation report based on the information obtained, and find out close contacts. "All confirmed cases need to report directly within 2 hours and complete epidemiological investigations within 24 hours."

Race against time to catch time with the spread of the virus. Tong Yeqing said that finding the source of infection of the case as soon as possible, clarifying the transmission chain, and then taking targeted measures to cut off the transmission route, choking the virus' "throat" from the source, is the key to controlling the spread of the epidemic. "Especially in the case of a clustered epidemic, the flow of indicator cases (referring to the patients who first developed the disease in a clustered epidemic) is critical. If one minute is late, the virus will be 'free' for one more minute, and the risks can be imagined. "

"Our team is on standby 24 hours a day, and it is common to conduct investigations in the middle of the night," said Tong Yeqing. Regardless of whether it is an isolation point or an ICU ward, the dispatcher must visit the front line of the epidemic situation. "It takes at least 30 minutes to communicate with a patient. Sometimes the patient's voice is so weak that he can hear the other person clearly. The flow meter cannot be taken out, and the teammates outside the ward can take pictures and save them."

Interrogating the case is the first step, then collating the information, entering the database, analyzing and writing the investigation report, and the whole process is linked. "Everyone in the team is in a" wartime "state. When they are sleepy, they fall asleep. The rest of the time is basically on work." Tong Yeqing said.

Seemingly humble information turns survey peaks

"Where have you been from? Where have you been? With whom have you been in contact?" ... The courier faced a large amount of fragmented information, so that "sand rushing for gold" to find key clues and successfully seize the real "fierce" need to be strong Comprehensive quality.

"It's not enough for a facilitator to have only professional knowledge, but also to have good communication skills and strong logical reasoning skills." Tong Yeqing said that it is particularly critical to obtain real information during the "discussion" process, and some people are out of various concerns. May be unwilling to cooperate. "At this time, we must be patient and explain the harm to each other clearly. Cooperating with the investigation is not only to protect ourselves, but also to allow relatives and friends who are in close contact with them to receive medical observation in isolation as soon as possible to reduce the risk of spreading others."

Shifters are also "detail control." Tong Yeqing remembers going to the ward with colleagues to investigate the sexual outbreak late at night. "We have been asking for a long time, but the patient's onset time and transmission logic have not been smooth." Finally, the patient recalled a seemingly inconspicuous detail: "When I attended the meeting two days before the onset, an unfamiliar person next to me People have cough symptoms. "This information became the key to Tong Yeqing's" solving the case ". The fragmented information eventually formed a complete puzzle, and the first case of the clustered epidemic came to the fore.

"Through investigation, we can exhaust all our close contacts and earn time for prevention and control," said Tong Yeqing. A large number of epidemiological investigations will also reveal the epidemic law of infectious diseases, which provides a professional for the research and judgment of epidemic trends and the development of prevention and control strategies. support.

The situation of the epidemic is improving, and public awareness of prevention and control cannot be lax

At this stage, the rapid rise of the epidemic in Hubei Province has been contained. Tong Yeqing believes that "at the later stage of the epidemic, an accurate epidemiological investigation is needed. It is necessary to find out whether all the cases are in the sight of management and to find, judge and control the source of infection more comprehensively."

"In some key places and regions, we require" one case, one warning, one verification ", so that early detection, early isolation, early diagnosis and early treatment can be achieved." Tong Yeqing said.

He said that better trends do not mean that the public can relax their vigilance. "Everyone still wears a face mask to wash their hands frequently. The home should be ventilated more than twice a day, and no virus can be used."

Since the outbreak of the epidemic, Tong Yeqing's "flow team" has fought more than 60 days and nights in the field. "The work will only come to an end when the epidemic situation in the province is completely over and the final evaluation is completed." Tong Yeqing said: "Now everyone is still full of fighting power, and the epidemic will not retreat and we will not withdraw troops." Finish)
