At present, the Omiljung variant has become the dominant popular strain in the world. The Aomi Kerong variant was first imported into the mainland on December 9 last year. Recently, many places have reported the detection of infection cases of the Omikejung variant, which has aroused widespread concern. How pervasive is Omiljung? Does the vaccine still work? Experts from the Chinese Center for Disease Control and Prevention gave the latest answers to relevant questions.
The data showed that the spread ability of Omi kerong was enhanced compared with other mutant strains. On the 23rd of last month, the World Health Organization issued a briefing showing that the renewal rate of the Home of Thermokeron was 15.8%, higher than Delta's 10.3%. According to the WEBSITE OF THE CDC, in the week from December 26 last year to January 1 this year, 95.4% of the new crown cases in the United States were infected by the Omi kerong strain.
However, the Omiljunn variant does not fully immunize to existing vaccines. Although the ability of existing vaccines to prevent infection with Omexjong has declined, it is still effective in preventing severe illness and death. The Omikejunn variant was not found to cause an increase in severe illness and mortality. In addition, the genomic analysis of the Omikerong mutant strain showed that its mutation site was not located in the primer and probe target area of the nucleic acid detection reagent published in the eighth edition of the "Novel Coronavirus Pneumonia Prevention and Control Plan" in mainland China, which did not affect the sensitivity and specificity of mainstream nucleic acid detection reagents in mainland China.
