Wearing heavy protective clothing, running through townships and towns to take samples from homes, and come in contact with the virus at "zero distance" every day ... Among the medical staff fighting the new crown pneumonia epidemic, there is a group of "invisible" front-line personnel who use the nucleic acid in their hands. Detecting "weapons" and the immortal "lights" in the laboratory confront viruses. They are the new coronavirus nucleic acid testers. How did these groups of grass-root nucleic acid testers known as the "captors" of the new crown virus catch the "devil"?

"After the outbreak, the Wanzhou District Center for Disease Control and Prevention set up a nucleic acid testing team consisting of 27 people to perform sampling, testing, and killing work, and always insisted that the specimens be tested on the day and the day after the day." Chongqing Wanzhou District Center for Disease Control and Prevention The chief of the inspection department, Lang Zhongkai, said that after each report is issued, the team members summarize the detection technology, optimize the detection process, improve the detection accuracy, and maximize the amount of specimens.

The reporter learned from the Chongqing Wanzhou District Center for Disease Control and Prevention on the 16th that the Center for Disease Control and Prevention of the district received a report of suspected cases of new coronary pneumonia infection on the evening of January 19, and the emergency plan was started immediately after the first confirmed case of imported new coronary pneumonia was diagnosed. Established a new crown virus virus detection team.

At the beginning of the outbreak, the sampling team was busiest. Every day, the sampling team went to the Wanzhou District Center for Disease Control and Inspection to collect protective masks, hats, gloves, shoe covers, protective clothing and disinfection water and sampling boxes. Then went to town and township streets to carry out household sampling.

27-year-old sampler Yang Yiduo introduced that her task was to concentrate on sampling at isolated points. With the active cooperation of the sampled personnel, the sampling work only takes about one or two minutes, and this is the moment when the sampling team is closest to the virus, and it is also the most dangerous moment.

"The swab may cause discomfort when entering the nasal cavity, throat, throat, and vomiting." Yang Yiduo said that the sampling team must not only patiently appease the mood of the sampled person, but also complete the sampling quickly.

"At the busiest time, we transferred more than 160 sampling staff from various medical institutions, divided into 80 sampling teams, and completed the sampling of 2,500 people a day at the most." Said Cheng Yonghong, the sampling team leader of the nucleic acid testing team.

Samples of suspected cases of New Crown Pneumonia taken by the sampling group daily were tested for nucleic acid in the New Crown Virus Laboratory of the CDC. The nucleic acid tester Gan Yulu said that it takes at least 6 hours from virus inactivation, nucleic acid extraction, system preparation, and on-line amplification to the final result analysis. The nucleic acid detection process is not only complicated and cumbersome, but also full of dangers. It is a source of infection, and shocks and centrifugation of nucleic acid extraction may produce aerosols, and you may expose yourself if you are not careful.

With the expansion of Wanzhou nucleic acid testing, more and more samples have been added, and the testing tasks have been placed on the testing staff. Gan Yulu, 25, has lived in the unit since January 20, and rotates day and night with colleagues.

"For consumables such as suction tips for samples, containers for samples, and medical waste such as protective supplies used during the experiment, we will arrange professionals to collect and pack them, autoclave them, and then follow the relevant regulations. It will be handed over to the medical waste disposal company for treatment, "said Zhang Hongqiong, the chief of the quality management section responsible for laboratory disinfection.

According to statistics, as of March 15, the team of the New Crown Virus Nucleic Acid Test of Wanzhou District Center for Disease Control and Prevention has carried out a total of 27,948 new crown virus nucleic acid tests, achieving zero infection for laboratory personnel.
