Evening News | American Expert: Omi kerong will be replaced by a new strain

1. 19 new locally confirmed cases were added in 31 provinces

At 0-24:00 on January 22, 31 provinces (autonomous regions and municipalities directly under the Central Government) and the Xinjiang Production and Construction Corps reported 56 new confirmed cases. Among them, 37 imported cases (13 cases in Shanghai, 6 cases in Zhejiang, 5 cases in Guangdong, 4 cases in Sichuan, 4 cases in Yunnan, 3 cases in Shandong, 1 case in Fujian, 1 case in Guangxi), including 14 cases from asymptomatic infected people to confirmed cases (6 cases in Zhejiang, 4 cases in Sichuan, 3 cases in Guangdong, 1 case in Guangxi), 19 cases in local cases (9 cases in Beijing, including 6 cases in Fengtai District, 2 cases in Fangshan District, 1 case in Haidian District; 5 cases in Tianjin, all in Jinnan District; 3 cases in Guangdong, all in Zhuhai City; 1 case in Henan, in Anyang City; 1 case in Yunnan, In Xishuangbanna Dai Autonomous Prefecture), including 1 case converted from an asymptomatic infected person to a confirmed case (in Beijing). There were no new deaths. There were 3 new suspected cases, all of which were imported from abroad (all in Shanghai).

2, the United States experts: Omi kerong will be replaced by the new strain

On January 21, local time, according to CNN, Yvonne Maldonado, an epidemiologist and infectious disease researcher at Stanford Medical School, said that after the Omilton mutation, another new new coronavirus strain may hit, and then the Ami kerong mutation will be replaced, but the new crown virus may never disappear completely.

According to Data from Johns Hopkins University in the United States, the number of confirmed COVID-19 cases in 14 U.S. states has fallen by at least 10% compared to last week, but the number of confirmed cases in 26 states has risen by at least 10%. In some areas of the United States where the Aumechjong variant first appeared, such as Boston and New York, the outbreak appears to have reached or passed its peak. But in other areas, such as Georgia or Atlanta, the mutant is still raging.

3, Fauci: The probability of re-infection of Omikeron by convalescent people is very low, but the worst case scenario may still occur

According to the Lianhe Zaobao, Fauci, the chief medical adviser to the US White House, said at a press conference that the probability of a person re-infecting Ami keron is low, at least in the short term.

Cases of re-infection are usually two infections with different mutant strains, he said. If a person who has recovered from COVID-19 has developed a good immune response, it is unlikely that they will be re-infected with the same variant strain for at least a few months.

But Fauci stressed that the worst-case scenario could still occur, that is, the emergence of new mutated strains, which invalidated the immunity and vaccine effects generated by previous infections, and the United States must be prepared for this.

4. The serum of early recovered people after one year of rehabilitation has a sharp decline in the ability of serum to neutralize the Omikejong variant

A study conducted by the research team of the State Key Laboratory of Virology of Wuhan University in collaboration with the scientific research team of the Hubei Provincial Center for Disease Control and Prevention showed that the serum neutralization ability of the Aumechjong variant after one year of recovery in Wuhan has dropped sharply, and the research results were recently published in the international academic journal Emerging Microbes & Infections. Lan Ke, director of the State Key Laboratory of Virology at Wuhan University, said in an interview with the Global Times that the study showed that the immune escape of the Aomi Kerong variant on people who have recovered from the new crown is very significant. But another data from this study suggests that covid-19 survivors and vaccinators who have completed vaccination with a booster vaccine have significantly increased their levels of neutralizing antibodies to Omi kerong.

On 11 January, WHO released a weekly epidemiological report on COVID-19, which noted that with the spread of the Olmiqueron strain, the prevalence of the Delta strain began to decline, and community transmission of the Olmiqueron strain has begun in many countries. According to WHO, the Omikeron strain has significant transmission advantages and is rapidly replacing other strains as the main epidemic strain. At present, many foreign studies have shown that the Omiljung variant has a strong immune escape ability, which can reduce the neutralization activity of many monoclonal antibodies and weaken the immune protection effect of vaccinated or infected people who have recovered.
