The number of new local infections in my country is still high

The scope of the epidemic affected by the city continues to expand

  Mi Feng, spokesperson of the National Health and Medical Commission, said that at present, the number of newly confirmed cases in the world has rebounded for the second consecutive week.

It is necessary to continue to adhere to the general policy of "dynamic clearing", improve epidemic monitoring, early warning and emergency response capabilities, scientifically organize nucleic acid and antigen testing, and promote the collection of infected people and close contacts. In every link, the community transmission of the epidemic will be completely blocked, and the social face will be cleared as soon as possible.

Since March, 31 provinces have reported more than 56,000 local infections

  Lei Zhenglong, deputy director and first-level inspector of the National Health Commission's Bureau of Disease Control and Prevention, said that from March 1 to 24, a total of more than 56,000 local infections were reported in 31 provinces, affecting 28 provinces.

  The epidemic situation in Jilin Province is still at a high level. From March 1 to 24, a total of more than 29,000 infected people were reported, and more than 1,000 new infections were added every day for several consecutive days. The epidemic situation in Jilin City and Changchun City is in a continuous development stage.

  The epidemic situation in Shanghai, Hebei, Fujian, and Liaoning provinces has grown rapidly in recent days, and the risk of community transmission in the places where the epidemic occurred continues to exist.

  The epidemic situation in Qingdao, Weihai, Zibo in Shandong Province, Shenzhen and Dongguan in Guangdong Province has been initially controlled.

  The epidemic situation in Beijing, Chongqing, Zhejiang Province and other places has stabilized.

Screening of "space-time companions" can maximize the detection of potentially infected people

  Wu Zunyou, chief expert of epidemiology at the Chinese Center for Disease Control and Prevention, introduced that "time-space accompaniment" is sometimes called "space-time intersection", which generally refers to staying together for a period of time within the same time and space grid as patients diagnosed with the new crown within 14 days people.

For example, if an infected person has been to a certain place within 14 days, and someone has intersected with him in the trajectory of these 14 days, he may be identified as a space-time follower.

Screening of "space-time companions" can identify potentially infected groups to the greatest extent, and include more people who have "space-time overlap" and may be infected into key investigations, so as to achieve early detection and advance prevention and control.

212 million seniors over 60 have completed the whole course of the new crown virus vaccine

  Wang Huaqing, chief expert on the immunization program of the Chinese Center for Disease Control and Prevention, said that 212 million people over the age of 60 in my country have completed the entire course of vaccination against the new coronavirus.

From the analysis of adverse reaction reports after vaccination, the incidence of adverse reactions reports in the elderly aged 60 and above is lower than that in other age groups.

Judging from the incidence of adverse reactions monitored, it does not show that the elderly over 80 years old are more prone to adverse reactions.

COVID-19 is not a "big flu"

  Wu Zunyou said that some studies have made a comparative analysis of the case fatality rate and mortality rate in the two time periods of August-October 2021 and November-January this year. The first three months were dominated by the epidemic of delta strains. , the next three months were dominated by the Omicron strain.

The case fatality rate did drop during the Omicron epidemic, but the total number of deaths or fatalities due to the outbreak was higher during the same period than during the delta strain.

This shows that the prevalence of the Omicron strain has not reduced the overall harm to a country.

This also suggests that the harm of the Omicron strain is still serious, and the new coronary pneumonia is not a "big flu".

Antigen testing cannot replace 48-hour nucleic acid testing

  Can an antigen result be used as a negative certificate?

Wang Guiqiang, director of the Department of Infectious Diseases at Peking University First Hospital, said that antigen testing is an important supplement to viral nucleic acid testing, and cannot be used as a diagnosis of exclusion, nor can it be used as a substitute for 48-hour nucleic acid testing.

Because the antigen test has certain false positives and false negatives, in the case of a positive antigen test, the nucleic acid review must be carried out eventually.

But in the case of a positive test, we manage it in a timely manner to avoid the risk of further spread.
