According to the website of the Central Commission for Discipline Inspection and the State Supervision Commission, Chai Yaxin and Guan Xiaopu, Tianjin is facing the Aomi Kerong mutation that has ravaged many countries around the world. This is by far the largest number of cases of infection in our country caused by Omi Kerong.
In the early morning of January 8, Tianjin found two cases of positive nucleic acid tests for the new coronavirus among the willing inspection personnel and the active patients in the fever clinic, all of which belonged to the Aomi Kerong variant. As of 21:00 that night, Tianjin added 18 more positive cases. From 21:00 on January 8 to 21:00 on January 9, another 20 new cases of positive infection were added in Tianjin Jinnan District, and they have been transferred to the designated hospital of the city for further diagnosis and treatment. Epidemiological investigation, investigation and control of epidemic-related personnel, and environmental sample collection are being carried out intensively.
The current round of epidemic in Tianjin spreads quickly, is highly concealed and penetrating, and the community transmission may have continued for some time
The first two confirmed cases in Tianjin were infected with the Aomi Kerong strain, and the sequence of the Aomi Kerong strain of the imported cases previously found in the city could not be confirmed as the same chain of transmission. "At present, from the circulation investigation and investigation, no first 2 cases have been found to be related to imported cases from abroad." On January 8, Zhang Ying, deputy director of the Tianjin Municipal Center for Disease Control and Prevention, revealed at a press conference that one case was a child who had been studying in Tianjin, and the other adult worked in Jinnan District, and his home was in Nankai District, without leaving Tianjin for nearly 14 days, and there was no travel history of going to medium- and high-risk areas.
This round of the epidemic in Tianjin has shown the characteristics of fast transmission speed, strong concealment and strong penetration. In terms of the relationship between cases and the chain of transmission, the virus has been transmitted for at least three generations. "That is to say, although we discovered this outbreak in the early hours of this morning, it is possible that the spread in the community has been going on for some time." Zhang Ying said that it is not excluded that in addition to the sealing and control area, the control area and the prevention area, there may be other positive infected people.
"The virus is constantly mutating, but it can be noted that the proportion of mild and asymptomatic infected people is increasing. This brings difficulties to the prevention and control of the epidemic, because if it is a serious patient, it is easy to be detected, while mild and asymptomatic are relatively hidden and easy to be ignored. But as a source of infection, all three can transmit the virus. Jiang Qingwu, a professor at the School of Public Health of Fudan University, said.
At present, the infected people mainly involve the custodial institutions where the cases are located, school students and parents. "Omikeron can easily infect children." Virology expert Chang Rongshan pointed out that the human adaptability of Omi Kerong is not only manifested in the accelerated transmission rate and milder symptoms, "about 30% faster than the Delta variant, but the medical treatment rate is less than one-third", in addition to the trend of young age.

Tianjin strictly controls measures, does not leave Tianjin non-essential, carries out nucleic acid screening for all employees, ensures synchronous follow-up of work, and strives to meet the battle with high efficiency and refinement
On the evening of January 8, the Tianjin Municipal Epidemic Prevention and Control Headquarters issued Circular No. 1 of 2022, strictly controlling measures and not leaving Tianjin unless necessary.
From 7 o'clock on January 9, Tianjin launched nucleic acid testing for all employees, and all residents of Jinnan District, Nankai District, Dongli District and Xiqing District completed the nucleic acid testing of personnel in the area within 24 hours. From 7:00 a.m. on January 10, all residents of the other 12 districts completed the nucleic acid testing of personnel in the area within 24 hours.
"Nucleic acid testing is the fastest way to find cases at present, and it can find infected people in time, isolate personnel, and prevent the further spread of the epidemic." Yang Zhanqiu, a professor at the Institute of Virology of the Medical College of Wuhan University, said that the relevant personnel who have been in close contact with confirmed positive cases may be the outbreak point of the spread of the epidemic, and the virus will have an incubation period of 4 to 5 days, and there is a possibility of continuous growth of positive cases in the future.
At present, Tianjin has suspended offline training services and hosting services for off-campus education and training institutions, vocational training institutions, adult training institutions, and custodial service institutions. On January 9, all the interviews scheduled for the teacher qualification examination in Tianjin were cancelled, some subway stations were temporarily closed, and many scenic spots were temporarily closed.
At the same time, the relevant security work is also following up. Tianjin has launched a linkage emergency response mechanism for the supply of the masses, and the stock of vegetables in wholesale markets and supermarkets has increased from the level of supplying the city for 2 days to 3 to 4 days, and the stock of rice flour oil has increased from 20 days to 30 days. Tianjin's daily necessities market is currently well supplied and the price is stable.

The cumulative number of confirmed cases in the world exceeds 300 million, and internal and external defenses are facing challenges, and we will adhere to the "dynamic clearance" without wavering
Omikejon has ravaged the world and become the main epidemic strain in the United States, India and other countries. On January 4, the number of new confirmed cases in a single day in the United States set a staggering 1.02 million, and has remained high since then. According to the Associated Press, the "culprit" of the explosive increase in the number of infected people is Noneiqueron, which has replaced Delta as the main epidemic strain in the United States.
WHO warns that the increasing number of infections in Omilon globally could increase the risk of more dangerous new variants. "Although from an individual point of view, the risk of hospital admission to infection with Opichron appears to be lower than that of Delta, the sheer number of infections may pose a greater threat." Catherine Smallwood, who is head of the WHO European Regional Emergency Project, said.
As of now, the cumulative number of confirmed cases of covid-19 in the world has exceeded 300 million, and the average number of new confirmed cases in the past week is close to 1.9 million, more than twice the peak of the previous wave of the epidemic. What is certain is that the global epidemic situation is still in a state of pandemic, and due to the relaxation of control in many countries and the easy occurrence of infectious diseases in winter and spring, the pressure on China's foreign defense has further increased.
"Dynamic zero clearance" is China's "magic weapon" to control the epidemic. "'Dynamic zeroing' is the most correct decision, whether from the perspective of practical effects or social effects, and it is also necessary to adhere to this policy without wavering in response to Aumequeron." Jiang Qingwu said.

People first, life first is the starting point and foothold of all prevention and control measures, quickly and accurately implement the "dynamic zero clearance", and achieve the greatest results at the smallest cost
"Dynamic zero clearance" is not "zero infection", but in the normalized prevention and control stage, it is necessary to maximize early detection, early diagnosis, early isolation, and early treatment, and resolutely prevent the continuous transmission of the epidemic community. When there are no local cases, maintain a high degree of vigilance; in the emergence of local cases, timely detection, rapid disposal, accurate control, and effective treatment.
"We don't have the ability not to have a local case now, but we have the ability and confidence to quickly extinguish the epidemic when we find that there are local cases, and we are not pursuing 'zero infection', but pursuing the fight against the epidemic as soon as possible." Liang Wannian, head of the expert group of the National Health Commission's leading group for epidemic response and handling, said.
So, what is the specific path to achieve "dynamic zeroing"? With the virus mutating and the risk of importing the epidemic abroad increasing, how can we control the epidemic during an incubation period?
In this regard, Liang Wannian summed up the "five precisions": one is to accurately find the source of infection, mainly through nucleic acid detection and screening; the second is to accurately identify close contacts, mainly through epidemiological investigation and big data technology; the third is to accurately delineate the epidemic area, epidemic point, and control scope, mainly through comprehensive research and judgment; fourth, accurately take prevention and control measures to achieve effective, landing, temperature and sustainability; fifth, accurately balance the relationship between epidemic prevention and control and normal production and life.
In the third winter of the fight against the epidemic, is China's epidemic prevention system enough to deal with mutant strains like Omi Kerong? "I am very confident that our country's epidemic prevention system will respond to mutants like Ami kerong." Liang Wannian said confidence comes from many sources, one of which is higher vaccination rates.
Actively and proactively vaccinate against covid-19, while protecting yourself, but also fulfilling your responsibility for effectively controlling the spread of the new crown virus. Up to now, more than 2.8 billion doses of COVID-19 vaccine have been administered nationwide, and more than 1.2 billion people have been vaccinated.
