(Fighting New Coronary Pneumonia) Nucleic Acid Detector Xing Fangchao: Close-up "stand-off" virus for one month
China News Network Bayannaoer March 1st: Question: Xuan Fangchao, a nucleic acid detector: Close-up "face-off" virus for one month

"Nucleic acid test results are an important basis for the diagnosis of patients with new coronary pneumonia, so every test we run at the same time." Taking off protective clothing, lying on the unit's march bed, this work rhythm Xing Fangchao has persisted for more than a month.
"Post-90s" Xing Fangchao is the deputy section chief of the Microbiology Laboratory of the Bayannur Disease Control Center in Inner Mongolia Autonomous Region and a member of the local new crown pneumonia epidemic inspection team.
After the new crown pneumonia epidemic occurred, Xing Fangchao led the inspection team to stay at their posts, fight the virus at zero distance, and provide scientific testing data for the detection of new crown pneumonia virus and lock out the scope of the epidemic. Viral nucleic acid detection work.
Xing Fangchao's daily work starts with getting the specimens, and each step needs to be treated with caution in nucleic acid extraction, PCR system configuration and loading, information collation, and results reporting.

"The most critical and most dangerous step is the nucleic acid extraction and sample addition, which cannot be replaced by a machine. You need to manually repeat the actions of opening, removing, and adding samples." Xing Fangchao said that they detect more than 70 samples per day, the most. Time to reach 120.
Contacting the virus at such a close distance was like walking on the tip of a knife, and Xing Fangchao did not dare to relax for a moment. In order to make the test results in the first time, and at the same time not to contact the family, Xing Fang simply carried out "self-isolation", installed a camp bed in the office, and stood by for 24 hours.
"Some flag counties are sending samples very late, and some clinical emergency samples need to be tested immediately after they are delivered to provide clinical indicators for the clinic, so they will not go home." Xing Fangchao said, this year's New Year's Eve He spent his post and hasn't been home until now.
On January 27, Xing Fangchao's inspection team received the first batch of highly suspected samples of new coronary pneumonia from the designated hospital and immediately started testing. The detection result came out as positive, this is also the first confirmed case detected in Bayannaoer.

In the eyes of outsiders, virus laboratory inspectors wearing protective clothing and goggles are full of technology and mystery, but only they know the dangers and hardships.
Xing Fangchao told reporters that before each experiment, they had to wear several layers of protective clothing, N95 masks, protective goggles, double-layer latex gloves, and waterproof boot covers. It took more than 20 minutes to dress neatly.
After entering the closed biosafety secondary laboratory, you cannot eat, drink or use the toilet. You need to work continuously for 4 to 5 hours. "When the amount of test samples is large, they enter the laboratory 3 times a day and work for more than ten hours continuously." Xing Fangchao said.
Because of the need to do a good job of protection, every entry into the laboratory is a heavy manual labor for the inspector. The whole person was wearing a tight protective suit in a small space. Water vapor condensed on the goggles and obstructed his sight. He maintained a fixed posture for a long time and was sweaty.
When he walked out of the laboratory, his body was soaked, his nose was congested, and his face was covered with indentations. These were all normal things for Xing Fangchao. "I hope that our efforts will enable people to set foot in the park early and spring out." Xing Fangchao said.
It is reported that as of March 1, this test group has completed the detection of nearly 2,000 clinically suspected samples of the new coronavirus nucleic acid. (Finish)
