(People’s Daily Health Client Reporter Kong Tianjiao) The new virus variant Deltacron recombined by Delta and Omicron has been distributed in France, the Netherlands, Brazil and Denmark and many other countries were detected. Some people will question, when the two main virus variants, Delta and Omikron, infect the same individual, what will happen to the “Delta Chron” of the new virus variant?
Wuhan University epidemiology and health statistics professor Yu Chuanhua told the People’s Daily Health Client: “There is no need to panic in the face of the new Delta Coron strain, the coronavirus has its own ability to recombine. , mutation is a common response of the virus to adapt to human parasitism, and the continuous mutation of the virus is to be expected. Since January, the new strain has not spread at a worrying rate, and currently, there is no data to indicate that it will be faster than it. predecessors are more likely to transmit or cause more severe disease, so it is too early to be too concerned about the new strain of Deltacoron.”

Yu Chuanhua explained that the World Health Organization (WHO) has recently confirmed the discovery of a new strain of Deltacron (Deltacron). The strain was recombined, with the “stem” derived from delta, but the spike protein (which allows the virus to enter human cells) from Omicron. It will have features common to both Delta and Omicron strains. The new strain has also been found in the US, UK, Netherlands, Denmark and other countries since it was first detected in samples collected in France in January.
Among them, researchers at the Mediterranean Infectious Diseases Medical and Teaching Institute in Marseille, France, published an article on March 8 saying that they confirmed the existence of Delta Chron by genome sequencing, and that the variant has been Detected in several regions of France.
A new study published March 12 on the US Medical Research website shows that the Delta Chron variant has appeared in the United States. A U.S. Centers for Disease Control-affiliated laboratory in California has detected two cases of Delta Chron infection since January. According to the “Guardian” on the 11th, citing the British Health Security Agency, in addition to the Delta Chron variant found in the United States, the United Kingdom also found about 30 cases of infection.
The new crown epidemic data released by the Brazilian Ministry of Health on March 15 shows that the country has newly confirmed 52,094 cases in the past 24 hours, and the cumulative number of confirmed cases has exceeded 29.43 million. Brazil has confirmed two cases of the new crown infected with the “Delta Coron” strain, Brazil’s Health Minister Keiroga said on the 15th. The case of the “Delta Coron” strain was discovered during surveillance by the Brazilian health authorities. Keroga said that further monitoring of this new mutant strain is needed, and the current focus is to vaccinate people with a booster shot of the new crown vaccine. “The booster shot is very important.”
Yu Chuanhua suggested that “vaccination against Covid-19 has been shown to be effective against the most important Covid-19 outcomes ‘hospitalization, severe illness and death’, even in the face of new variants. Therefore, in the past, targeting The prevention and control measures of the Delta and Omicron strains are still effective for the new Delta Coron strain. Continue to increase testing efforts, monitor the evolution of virus variants, and ensure that corresponding prevention and control measures are taken. WHO also said : The COVID-19 pandemic is far from over, and we need to focus not only on saving lives and reducing serious illness and death, but also on reducing the spread of the virus.”
