News 1+1丨How can the Xi'an epidemic stop the transmission chain as soon as possible?
Xi'an, Shaanxi Province, started with 1 local confirmed case on December 9, 7 new cases on the 17th, 10 new cases on the 18th, and 21 new cases on the 19th. What stage is the epidemic situation in Xi'an?
For Xi'an, a large city with a population of tens of millions, how to block the chain of transmission as soon as possible?
What was the result of the first round of nucleic acid testing started in Xi'an on the 18th?
Headquarters reporter Li Zhi: Since the 18th, Xi'an has launched a nucleic acid test for all employees. Because there were some problems with the "One Code Communication" in Xi'an on the morning of the 20th, we have no way to get the latest data now.
As of the early morning of the 20th, Xi'an has completed a total of 16 million nucleic acid tests, and the previous inspection results are still being counted.
How to solve the problem in Xi'an "One-Code Communication" on the morning of the 20th?
Headquarters reporter Li Zhi: ①At around 7:40 in the morning on the 20th, the peak value of logging in to "Yi-code" exceeded the usual peak value by more than 10 times, which caused network congestion, which made some functions of "Yi-code" unable to be used normally. .
Now they have taken capacity expansion and current limiting and specific measures.
②The next step will be 24-hour non-stop on-site maintenance to strengthen system security, ensure the smooth operation of "one-code access", and also ensure that the epidemic prevention and control work can be carried out smoothly.
Xi'an announces three major transmission chains of the epidemic
Headquarters reporter Li Zhi: Community communication is now the focus of epidemic prevention in Xi'an.
① On December 9, a local confirmed case occurred in an inbound flight quarantine hotel.
②On December 12, there was one case in the Ziniu Outpatient Clinic, and no close contacts have been positive until now.
③On December 15th, there were 3 cases in Chang'an University. So far, the chain of transmission has exceeded 20 people, and there is a tendency to continue to expand.
Although Xi'an has done a lot of research work in the early stage, the specific channels of transmission are still unclear, and there is a lack of clear correlation between the various transmission chains.
Many positive cases were found in community testing, indicating that community transmission in Xi'an has begun.
The follow-up Xi'an epidemic will be in a rapid development stage, and the current risk of epidemic spread is still relatively high.
It is reported that Xi'an will start a new round of nucleic acid testing for all employees on December 21.
The Xi'an epidemic has now spilled over to Yan'an, Xianyang, Dongguan, and Beijing, four cities. It is urgent to cut the chain of transmission as soon as possible.
What is the current stage of the Xi'an epidemic?
Yu Chuanhua, a professor at the School of Public Health of Wuhan University: As the source of infection, the flight from Pakistan to Xi'an on December 4, the first confirmed case in Xi'an on December 9, has been several days in between.
Although the source of infection has been clarified, the transmission chain is still unclear, especially how it spreads among several chains. It is still unclear, so community transmission has already occurred.
With the nucleic acid test of West security personnel, the number of new cases will not be ruled out in the future.
How to block the transmission chain as soon as possible?
Yu Chuanhua, a professor at the School of Public Health of Wuhan University: If we want to cut the chain of transmission, it is nothing more than four mornings, that is, early detection, early diagnosis, early isolation, and early treatment.
We must find out early. Once there is an epidemic, we must use big data to perform some isolation control on close and sub-close connections, including our reservation of isolation places.
The other is to screen for suspicious cases, cut off the route of transmission, carry out strict scientific and precise division of different areas, and then monitor these key populations.
The local epidemic was caused by overseas imports. How to strengthen management and control?
Yu Chuanhua, a professor at the School of Public Health of Wuhan University: At present, it is still relatively serious overseas. In particular, the global number of new coronary pneumonia diagnoses has been rising for 8 consecutive weeks, and the epidemic situation abroad is still very serious.
At present, there are 50,000 to 80,000 new cases in countries such as Britain, the United States and France, so many people are somewhat paralyzed and relaxed.
At present, if we want to implement the early detection, early diagnosis, and early isolation just mentioned, we still have to implement normal control and carry out dynamic zeroing prevention and control measures.
