Students passing by were infected without wearing masks, and their family members who lived together had negative nucleic acid, and the secrets of the Dongguan circumstance were revealed
At 2 o'clock in the morning, on the 4th floor of a hotel in the center of Dongguan, several large conference rooms were brightly lit. People wearing purple vests with the words "China Health" were still busy. Some people made records on the computer while they were calling. Someone played back the video surveillance picture frame by frame.
This is the on-site working group for the prevention and control of the 6.18 epidemic in Dongguan, and the base camp for the on-site handling of the current round of the epidemic in Dongguan. Since June 18, 219 staff members have been fighting continuously and successfully blocked the further spread of the epidemic. McDonald's came into sight for the first time. On June 18, Li Moumou, who lives in the "Baiyue Shangcheng" district, came out with a positive result of the initial nucleic acid test, and the on-site work team took immediate action. Because Li's life is very regular and has never left Dongguan, her husband was not diagnosed at the time. How she was infected at one time caused the disposal staff to be puzzled. Li Moumou recalled that when he returned to her mother-in-law's house on the evening of June 12, the family once went to the McDonald's restaurant in Mayong Galaxy City Plaza. Earlier, the spread of the epidemic in Guangzhou occurred in the restaurant, which made the staff immediately alert. McDonald's entered the vision of disease control personnel. The students passing by without wearing masks, Galaxy City Plaza is the most prosperous place in Macong Town, and there are many people entering and exiting the McDonald's restaurant. At around 7:50 pm on June 12th, Li and her husband took their family to the first floor and went to the second floor to have a meal. Almost at the front and back, Jia and Jing from the Dongguan campus of Guangzhou Xinhua University also entered McDonald's. Multiple video surveillance in the restaurant restored the intersection of two young faces and a certain Li. After Li’s family sat down on the second floor, Jia and Jing also went upstairs. The two did not wear masks, but they passed Li’s dining table at close range. During the period, Li was not wearing masks and was talking with his family. . The screen shots were handed over to the public security department for technical processing, and they must be found out. At the same time, repeated inquiries to the store manager are ongoing. The store manager mentioned that there are students from Xinhua College working part-time in the store; the identities of Jia and Jing were quickly confirmed, and they were from Xinhua College.
The initial circle is right. Xinhua University (Dongguan campus) has 18,000 teachers, students and family members. How to circle the students who have been to McDonald's on the evening of June 12 is difficult and urgent. After visiting and sending out questionnaire stars one by one, the reconnaissance and platoon team did their best. Before the screening was completed, they initially drew a circle with Jia and Jing among them. On June 20, Jia was diagnosed; on June 21, Jing was diagnosed. The entire field team felt confident because of preparations in advance. So far, there have been no new cases in this round of the epidemic in Dongguan, and the epidemic has entered a relatively stable stage. This circle of contributions is indispensable. The circle is right, and the circle is timely, otherwise, the consequences are unimaginable. The child and mother-in-law who lived with Li XX had 4 nucleic acid tests, and the results were all overcast. Who would have thought that Jia and Jing would be infected the moment they passed by. "This is the weirdness of the Delta strain," said Huang Zhenyu of the Dongguan Centers for Disease Control and Prevention. "The way the virus spreads is magical." If children in close contact are not infected, outsiders will be infected. What is the reason? The on-site team members are also very puzzled. "The recent local outbreaks of Delta mutant strains that occurred in Guangzhou, Shenzhen and Dongguan are the first head-to-head confrontation with Delta mutant strains. At present, we are still unclear on many aspects of Delta mutant strains, and we cannot judge why this is the case." Zhang Zewu, leader of the on-site prevention and control working group, said. Sleep tightly, and set off at any time. Academician Zhong Nanshan pointed out, “The Delta strain has a high load, and the exhaled gas is very toxic and highly infectious. In the same space, the same unit, the same building, and the same building, the disease In the first four days, the people who got along with these patients were all close contacts." This posed a huge challenge to the handling of the epidemic. As of 0:00 on June 24, 4 confirmed cases (including Li's husband Xiao) were initially determined to have close contacts with 2,552 people in Dongguan, and 2,518 people with close contacts once. This is an unprecedented and huge workload. “Last year, when the epidemic was at its worst, it was not so difficult!” said Luo Dong, deputy director of the Municipal Center for Disease Control and Prevention.
After the outbreak, the one-year aid to Tibet ended on June 11. Huang Zhenyu, who had just returned to Dongguan, joined the fight. From 9 pm on June 19 to 3 am on June 21, he has been carrying The team worked at the school and slept for less than 4 hours in between. "I didn't feel tired at the time, so I would drink water when I was tired." This is Huang Zhenyu's challenge state. Yang Sheng, a member of the 4th squadron of the flow adjustment group, returned from a military medical career. From 8 pm to 3 am the next day, he watched the video surveillance without missing a minute. Only the patient’s time was fully closed and the premises were fully covered. , The stone in his heart can be put down... At 10:48 on June 27th, Dongguan issued a notice announcing the release of 13 key areas for closed management and the release of key areas for closed management in Mayong Town. , Dongguan is gradually returning to normal. This is what the staff of the on-site epidemic prevention and control team are most looking forward to. They can finally get a good night's sleep.
