(Fighting against New Coronary Pneumonia) China's CDC responds to "Delta Chron": normalized measures can prevent and control large-scale epidemics

  China News Agency, Beijing, March 19 (Reporter Li Chun) The Joint Prevention and Control Mechanism of the State Council of China held a press conference on the 19th.

When answering a question about the "Delta Chron" strain, Wu Zunyou, chief epidemiologist at the Chinese Center for Disease Control and Prevention, said that the prevention and control practices over the past two years have proved that normalized prevention and control measures can effectively prevent and control mutant strains caused a large-scale epidemic.

  According to media reports, WHO experts recently confirmed that the "Delta Chron" strain has been found in several countries.

The emergence of this new variant strain recombined from the strain has drawn people's attention to its harm and countermeasures.

  "Recently, the World Health Organization did confirm the emergence of a new strain, which is a new variant of the recombination of the two strains after a patient was infected with both the Delta and Omicron strains. Virus strain." Wu Zunyou said that it has been observed that this recombinant strain is recombined by Delta AY.4 type and Omicron BA.1 type, the main body is the delta strain, and the secondary protein part is mainly composed of Omicron BA. composition of strains.

  Wu Zunyou said that the reports of this strain are mainly found in several European countries, and the number of reported cases is only a few dozen.

From these limited data, whether epidemiological or clinical, no significant changes have been observed in the recombinant strain, which is similar to the Delta and Omicron strains.

  However, due to the short time of discovery of the new strain and the relatively small number of cases, no conclusions can be drawn about its pathogenicity, infectivity, and ability to escape from vaccines.

"Now the World Health Organization and related countries are closely monitoring this strain to understand its movements, and if it changes, it will alert the world in time."

  Wu Zunyou said that the mutation of the new coronavirus has been happening in the past two years.

Whether it is the mutant strain Delta, Omicron, or a new mutant strain, the prevention and control practices in the past two years or more have proved that normalized prevention and control measures can effectively prevent and control the large-scale epidemic caused by the mutant strain.

  The expert pointed out that for ordinary people, three main prevention and control measures should be taken:

  One is vaccination.

Those who have not been vaccinated should be vaccinated as soon as possible, and those who need a booster shot should be given a booster shot. "Vaccination is the basis of our prevention and control."

  The second is to adhere to the public health measures of normalized prevention and control, which must be implemented.

Wear masks, maintain social distance, pay attention to hand hygiene, and maintain ventilation in places where people are concentrated. "These conventional prevention and control measures are effective for the prevention and control of mutant strains."

  The third is to pay attention to the changes in the epidemic situation, and more importantly, to abide by the relevant regulations on epidemic prevention and control in the work unit, residential community, and various places where you go, and implement these measures.
