China.com, October 13 (Reporter Peng Yao) The State Council’s Joint Prevention and Control Mechanism held a press conference on the 13th. Experts responded to hot issues such as sequelae of the new coronavirus and the infection rate indicators of the new coronavirus pneumonia.
How is the comparison between my country and the world in indicators such as the infection rate and mortality rate of the new coronavirus?
Chief Epidemiology of the Chinese Center for Disease Control and Prevention , introduced that in the past three years, everyone in the world has been affected to varying degrees. Judging from the two indicators of disease and death, Chinese people are the least affected by the new crown.
As of October 10, the World Health Organization website announced that the United States has reported a total of 95,260,865 cases and 1,050,195 deaths. China has reported a total of 254,066 confirmed cases, asymptomatic infections, 755,048, the total number of infections is 1009,114, and 5,226 deaths. The COVID-19 infection rate in China is 70 people per 100,000 population, which is 1/483 of that in the United States; the COVID-19 death rate in China is 0.4 deaths in China are 1/785 of that in the United States.
The proportion of China's population in the world is 18.32%, and the proportion of the number of new crown cases in the world is 0.16%. Calculate the incidence rate based on the population of one million, and the incidence rate is 1/112 of the world; the number of deaths accounts for 0.08% of the world; Calculate the mortality rate based on the population of one million, and the mortality rate is 1/229 of the world.
Wu Zunyou said that whether it is comparing the epidemic prevention and control effect in the United States or the overall global epidemic prevention and control effect, China is an absolute "outstanding student". "We have no reason to be unconfident and no reason to doubt our prevention and control strategy." What changes have the pathogenicity and transmission power of the sub-branch of the BF.7 mutant strain BF.7?
Recently, the sub-branch of the Omickron variant BF.7 was detected in mainland my country for the first time. Dong Xiaoping, chief expert of virology of the Chinese Center for Disease Control and Prevention, introduced that virus mutation is a very common natural law, reflecting the reaction of viruses as small and simple microorganisms to external pressure, which is more fully manifested in the new coronavirus. Although the new coronavirus has only appeared for more than two years, the mutation rate has significantly accelerated when a large number of naturally infected people and a larger number of vaccinated people exist.
study found that since the emergence of Omickron in 2022, the rate of mutation of the virus has significantly accelerated. The so-called BF.7 sub-branch is the abbreviation of BA.5.2.1.7, and is essentially an evolutionary branch of the Omickron BA.5 variant. Since the BF.7 sub-branch was detected in September, it has gradually become common in many countries and is a strain that accounts for a certain proportion. The global share increased from around 3.5% in late September to 11% in the previous week.
Dong Xiaoping said that the BF.7 sub-branch and other Omickron evolutionary branches were very similar to BA.2 and BA.5 when they first appeared, and both showed relatively strong transmission capabilities. However, whether BF.7 can become the dominant strain of the world in the next stage needs to be observed. At present, the pathogenicity of the evolutionary branch of BF.7 has not been significantly enhanced.
What is the latest situation of the current COVID-19 vaccination in my country?
, Director of the Department of Defense of the National Bureau of Disease Control and Prevention and First-level Inspector Lei Zhenglong introduced that as of October 12, 2022, the total number of new coronavirus vaccine was reported to be 63.437.851 million doses of new coronavirus vaccine were reported, covering 1.33.43 million people, of which 1.271.711 million people have been completed, and the number of people covered and the number of people covered accounted for 92.45% and 90.2% of the total population in the country respectively. 87.832 million people have completed strengthening immunization. 239.216 million people over 60 were vaccinated, and 227.865 million people were vaccinated. The number of people covered and the number of people vaccinated accounted for 90.6% and 86.3% of the total population aged 60, respectively. The number of people strengthened immunization was 177.568 million.
What are the latest research on the sequelae of COVID-19 at home and abroad?
Wu Zunyou introduced that the sequelae of the new crown is also called the long-term symptoms of the new crown. The definition of clinical cases released by the World Health Organization in October 2021. The sequelae of new coronavirus usually occurs within 3 months after the onset of the new coronavirus infection. It can be that certain new symptoms appear after recovery from acute infection, or some symptoms persist during the original acute infection period, and the symptoms last for at least 2 months. These symptoms can occur repeatedly and cannot be explained by other diagnoses.
According to global research results, health problems with a wide range of health problems, including: fatigue or fatigue, thinking disorders or inability to concentrate, shortness of breath or difficulty, headache, dizziness, accelerated heartbeat, chest pain, cough, joint or muscle pain, depression or anxiety, fever, loss of smell or taste, etc. These symptoms can last for weeks, months, or even longer. The sequelae of the new coronavirus are common in severe cases, but can also occur in mild cases. Generally speaking, people who have been vaccinated have a much lower risk of sequelae after being infected with the new crown than those who have not been vaccinated.
Wu Zunyou said that the best way to prevent the sequelae of the new coronavirus is to prevent the new coronavirus infection. Therefore, my country continues to adhere to the overall strategy of "preventing imports from outside and rebound from inside" and the general policy of "dynamic clearance" are not only an important strategic means to control the large-scale epidemic, but also an important method to prevent the new crown.
