2021 New Crown News: According to Worldometer real-time statistics, as of around 6:30 p.m. Beijing time on September 4, the cumulative number of confirmed cases of New Crown pneumonia worldwide exceeded 220 million cases, and the cumulative number of deaths exceeded 4.56 million cases, according to a report on September 4. The global single-day new confirmed cases exceed 700,000 cases, and more than 10,000 new deaths. The data also show that the United States, India, the United Kingdom, Iran, and Brazil are the five countries with the highest number of new confirmed cases. The United States, Mexico, Brazil, Russia, and Indonesia are the five countries with the highest number of new deaths. At a time when the global New Coronavirus outbreak continues to spread, the New Coronavirus has mutated again and has infected 39 countries.
According to data from the Global Initiative for Shared Influenza Data (GISAID), more than 4,500 mu (Mu) strain sequences have been recorded in 39 countries worldwide as of Aug. 29, according to a Sept. 4 report. The United States reported 2,065 cases of the Mu strain, far more than any other country, with Colombia, in second place, reporting 852 cases. The World Health Organization’s weekly global outbreak report released on August 31 noted that WHO named the new coronavirus B.1.621 as the Mu strain and on August 30 classified it as a variant of “interest,” which is lower than the Delta strain, which is a variant of “concern. The strain is classified as a “variant of interest” on August 30, which is lower than the “variant of concern” for the Delta strain. Preliminary data show that the Mew strain is similar to the Beta strain in that it weakens antibody efficacy. The weekly report also describes that the Mew strain was first confirmed in Colombia in January 2021.
According to WHO criteria, a “variant of interest” is one that possesses genetic mutations that affect the ability of the virus to spread, the severity of symptoms and immune escape. It is different from a “variant of concern,” which refers to a variant that can lead to a reduction in the effectiveness of public health strategies, vaccines or therapies. According to WHO, the Mew strain is considered a “variant of interest” because it possesses specific mutations that need to be studied for their potential impact on the human immune response, and data shared by the WHO Working Group on Virus Evolution suggest that immunity from prior infection or vaccination may not be as strong against this variant as it is against the original strain. the original strain, and further studies are needed to confirm this.
It is understood that the new coronavirus variant strain, Mew, is the indigenous variant strain found in the country, as confirmed by the Ministry of Health on September 2, local time in Colombia. The earliest patients infected with the strain date back to January of this year. Although the United States has the highest number of infections, some experts in the United States are unconcerned about this virus. Vanderbilt University professor and infectious disease expert Schaffner said that the mu strain was discovered in January this year, but only now was included in the list of variants “to watch out for”, is not very worrying, it is unlikely to exceed the severity of Delta virus. In addition, Johns Hopkins University Center for Health and Safety epidemiologist Adalia also believes that new mutant viruses will continue to be produced, and there is no reason to panic about mu mutant strains for the time being.
It’s worth noting that Mu is the fifth “variant of interest” listed by the WHO, with other “variants of interest” including Eta, Iota, Kappa and Lambda, according to The Hill. lambda. Lambda was first discovered in Peru, South America, and Iota was first discovered in the United States last November. In addition, the WHO currently lists four new coronavirus variants as “variants of concern”: the alpha variant, which has been seen in 193 countries, the beta variant, which has been seen in 141 countries, the gamma variant, which has been seen in 91 countries, and the delta variant, which has been seen in 170 countries. The WHO classified the Delta variant as a “variant of interest” in early April and as a “variant of concern” on May 11.
