(Fighting against New Coronary Pneumonia) is harder, higher, and bigger: three comparisons to see the current epidemic prevention and control in China
China News Agency, Beijing, April 1, question: harder, higher, bigger: three comparisons to see the current epidemic prevention and control in China

"We must always adhere to the general policy of 'dynamic clearing' and unswervingly. Time does not wait for me. We must be resolute and decisive, and implement various prevention and control measures in every link." Talking about the severe and complicated situation of China's recent epidemic prevention and control, on April 1st At the press conference of the Joint Prevention and Control Mechanism of the State Council, Mi Feng, a spokesman for China's National Health Commission, pointed out.
"Time does not wait for me", this is not only the theme of the press conference that day, but also the objective requirement of China's current epidemic prevention and control.
It is more difficult to achieve "dynamic clearing", the death rate of Omicron is higher than that of Delta in the same period, and the benefits of vaccination outweigh the risks. The above three comparisons can be used as an angle to observe China's epidemic prevention and control work.
It is more difficult to achieve "dynamic clearing" than before
In the past March, the number of newly confirmed local cases and asymptomatic infections in China increased rapidly, the epidemic spread in many places, and the scope of the spread was further expanded. Community transmission in some areas has not been interrupted, and spillover cases have been reported.
According to Lei Zhenglong, deputy director and first-level inspector of the National Health Commission's Bureau of Disease Control and Prevention, from March 1 to 31, a total of 103,965 local infections were reported nationwide, affecting 29 provinces. hair characteristics.
Lei Zhenglong pointed out that the recent overall improvement of the epidemic situation in most parts of the country shows that the prevention and control measures are effective.
However, China's epidemic prevention and control is still under great pressure of "foreign defense import, internal defense rebound". At the same time, the risk of Omicron epidemic in many places still exists, and the prevention and control situation is still severe and complicated.
Since the beginning of this year, the new crown pneumonia epidemic in China has been one after another.
Wu Zunyou, chief expert of epidemiology at the Chinese Center for Disease Control and Prevention, believes that the Omicron variant strain is highly contagious and spreads fast, coupled with a certain proportion of asymptomatic infections, making it more difficult to achieve "dynamic clearing" , may take longer.
The expert also pointed out that a more sensitive monitoring system is needed to detect the epidemic earlier and implement various prevention and control measures more quickly in response to the new characteristics of the mutated strain of Omicron, such as the invisibility and speed of transmission.
As long as the prevention and control measures are implemented strictly and quickly in every link, the goal of "dynamic clearing" can still be achieved.
Omicron's death toll is higher than Delta's
There are many mild cases and asymptomatic infections caused by the mutant strain of Omicron, so it gives people the illusion of "low harm".
Wu Zunyou pointed out that although the Omicron BA.2. strain had a relatively high proportion of asymptomatic infections, due to its rapid spread, a large number of infected people would be produced in a short period of time, and the total number of deaths was still very high. .
By analyzing the data released by some countries, it can be seen that the number of deaths caused by the Omicron variant strain during the epidemic is higher than that caused by the delta strain during the same period.
Wu Zunyou pointed out that this shows that the prevalence of the mutant strain of Omicron is still very serious to a country or region, and we must strive to control the epidemic in a short period of time.
This is also an important reason why China still needs to continue to adhere to the policy of "dynamic clearing".
Wu Zunyou said that to achieve "dynamic clearing", it is necessary to find and manage every infected person. For asymptomatic infected people, there is indeed a challenge of "difficulty in finding".
With the help of technical means, big data can be used to assist epidemiological investigations, clarify the transmission chain, trace close contacts, and discover asymptomatic infected persons on the transmission chain.
In addition, it is also possible to move the monitoring line of defense one step further, and through the monitoring mode of "antigen screening + nucleic acid diagnosis", asymptomatic infections can be detected as soon as possible and the chain of transmission can be cut off.
Vaccination benefits outweigh risks
"Timely vaccination is the most effective, economical and convenient measure to prevent infectious diseases, which is also a global consensus." Wang Huaqing, chief expert of the immunization program of the Chinese Center for Disease Control and Prevention, pointed out that whether it is for individuals or groups, vaccination against the new coronavirus The benefits of vaccines far outweigh the risks.
Wang Huaqing said that the "benefit" of vaccination refers to the effect of preventing disease, including preventing infection, morbidity, severe illness and death.
Studies have shown that the risk of severe illness and death can be reduced by more than 90% after the whole course of vaccination against the new coronavirus.
"Risk" mainly refers to the adverse reactions that occur during vaccination. "At present, we have seen that serious adverse reactions of all vaccines used are very rare."
Wang Huaqing said that the probability of serious adverse reactions is about one in a million.
In addition, Wang Huaqing also talked about another risk, that is, the risk of not vaccinating.
According to the data from the Centre for Health Protection of the Department of Health of the Hong Kong Special Administrative Region Government on March 29, the case fatality rate after infection with the new coronavirus was 0.1% among the whole population who had been vaccinated throughout the whole process, while the whole population who had not been vaccinated or vaccinated with one dose of the vaccine had a fatality rate of 0.1%. , the case fatality rate after infection is 1.91%, the difference between the two is nearly 20 times.
"From this, we can also see that the risks brought by not vaccinating are still very large," Wang Huaqing said. "Based on the above situation, the benefits of vaccination against the new crown are much higher than the risks." (End)
