China News Agency, Beijing, March 15th, title: China's anti-epidemic focus on five "numbers" against Omicron
China News Agency reporter Li Chun
Recently, local clustered epidemics have occurred in many places in China, mainly Omicron variant, which spreads quickly and is highly concealed.
Especially since March, the frequency of outbreaks has increased significantly, the number of infected people has increased rapidly, and the scope of infection has continued to expand.
To judge the current epidemic situation and deal with the increased difficulty of prevention and control, China's fight against the epidemic needs to focus on these five "numbers".
On March 15, an epidemic prevention checkpoint was set up on a road in Xianyang City, Shaanxi Province.
On the same day, the Office of Xianyang Epidemic Prevention and Control Headquarters issued a notice, including that all primary and secondary schools, kindergartens, and training institutions suspend offline teaching and carry out online teaching; the community implements closed management, and each household is allowed to go out to purchase and live with the entry and exit card every day. supplies, etc.
The official requirement of Xianyang City is not to leave the salt unless it is necessary, and not to enter the salt unless it is necessary.
All highway exits in the city, national and provincial trunk roads, and highway-city boundary entrances, as well as urban and rural roads adjacent to areas with confirmed cases, have established epidemic prevention and control inspection service points.

"Total": Over 15,000 infected people in 28 provinces
How to judge the current epidemic situation in mainland China?
At the press conference of the Joint Prevention and Control Mechanism of the State Council on the 15th, Lei Zhenglong, deputy director and first-level inspector of the National Health and Medical Commission's Bureau of Disease Control and Prevention, said that the current local clustered epidemics are characterized by many points, wide areas and frequent occurrences. The epidemic prevention and control situation is severe, complex and difficult.
Lei Zhenglong said that from March 1 to 14, the cumulative number of reported infections in the local epidemic has exceeded 15,000, affecting 28 provinces.
Recently, the epidemic situation in Jilin, Shandong, Shanghai, Guangdong, Hebei and other places is still developing. In some areas, the epidemic situation is rising rapidly, and the risk of social spread and spillover is high. Various places are speeding up the screening, transfer, and isolation of risk personnel. Work.
He also pointed out that at present, the response and disposal work in each epidemic area is progressing in an orderly and vigorous manner, and the overall epidemic situation is still under control.
"Percentage": more than 95% of mild and asymptomatic cases in Jilin Province
The increase in the proportion of mild cases and asymptomatic infections is a feature of this round of local epidemics.
Taking Jilin Province, where the number of newly confirmed cases has risen rapidly recently, as an example, Jiao Yahui, director of the Medical Administration and Medical Administration Bureau of the National Health and Health Commission, said that as of the morning of March 15, there were 8,201 hospitalized cases in the province, including 2 critically ill cases in Jilin City, There are 2 severe cases, 2 severe cases in Changchun City, and the common type accounts for about 4%.
"More than 95% of the patients are asymptomatic infections and mild cases."
Lei Zhenglong also pointed out that the clinical manifestations of infected people are mainly asymptomatic and mild, which leads to the latent spread of the epidemic and late detection, resulting in frequent local epidemics recently, which makes it more difficult to trace the source and prevent and control it.
On March 15, the Changchun International Convention and Exhibition Center "fangcang shelter hospital" was officially delivered and put into use immediately.
This is the first "fangcang shelter hospital" delivered in Changchun since the outbreak. It will provide more than 1,500 beds for patients with mild and asymptomatic infections of the new coronary pneumonia, and more than 700 beds as shelters for isolation.

"Multiple": Omicron's transmission power is about 2 times that of Delta
At present, the Omicron variant has become the dominant strain for imported and local epidemics in the world and outside China.
In the current round of epidemics in mainland China, mild cases and asymptomatic infections accounted for a large proportion. One of the reasons is the "cunning" of the Omicron variant.
Through epidemiological analysis of existing cases, the Omicron variant is about twice as capable of spreading as the delta variant, spreading faster and more infectious.
In addition, from the perspective of clinical manifestations, the symptoms of Omicron strain infection are not typical, similar to the symptoms of upper respiratory tract infection caused by other viruses, lack of specific manifestations, difficult clinical differential diagnosis, and more hidden virus transmission.
"Number of tubes": nucleic acid detection capacity of a single tube reaches 46.09 million tubes/day
In terms of responding to the current epidemic situation and implementing prevention and control measures, strengthening rapid nucleic acid testing is undoubtedly a powerful move to achieve the "dynamic clearing" policy.
Talking about the construction of nucleic acid detection capabilities, Jiao Yahui pointed out that China "is a global leader in nucleic acid detection."
As of March 13, a total of 12,400 institutions across the country have provided nucleic acid testing services for the new coronavirus, with an overall nucleic acid testing capacity of 46.09 million tubes per day.
At the beginning of this year, China further increased the nucleic acid detection mixed detection capacity to "20 mixed 1", which can increase the detection capacity of a single tube of 46.09 million tubes per day by 20 times.
In addition, the Comprehensive Team of the Joint Prevention and Control Mechanism of the State Council recently issued a plan to use antigen detection as an important supplement to nucleic acid detection, and to give full play to the "early" and "fast" advantages of antigen detection, which can target more asymptomatic infections of the Omikron strain, The characteristics of fast and hidden transmission, screening out infected people as soon as possible.
"Number": 210 million elderly people have completed the whole course of the new crown vaccine
The elderly are the key population for epidemic prevention and control.
Jiao Yahui said that according to current statistics, about 65% of severe patients with new coronary pneumonia are elderly people over 60 years old.
Among them, 80% had underlying diseases and 65% were not vaccinated.
"This is why the state advocates that the elderly, especially the elderly, should be vaccinated in time."
As of March 14, a total of 3,198.272 million doses of COVID-19 vaccines have been reported nationwide, with a total of 1,272,537,000 people vaccinated, and 1,239,171,000 people have been fully vaccinated.
Among them, 221.226 million people over the age of 60 were vaccinated, and 211.62 million people were fully vaccinated.
"Inoculation of the new crown vaccine can effectively reduce the severe rate and fatality rate." Lei Zhenglong also mentioned that it is necessary to promote the vaccination of the elderly, especially the elderly over 80 years old, coordinate the strengthening of immunization, and continuously improve the population vaccination rate. .
