[alert] COVID-19 is now a new variety. What is the difference between the United States and Delta? Who emergency reminder

Miao strain has been detected in 49 states in the United States.

According to the report of Fox News local time on September 7, CCTV news has detected the novel coronavirus mutant virus Miao strain in 49 states in the United States.

Infectious disease expert Dr.

Anthony Fauci said that the new coronal mutant virus Miao strain may be able to escape the protection of some antibodies.

According to Newsweek, California has the highest number of cases infected with Miao strain, with at least 384 Cases.

The Los Angeles County Public Health Department wrote in a statement, “the Miao strain is more infectious and has the potential to escape some antibody protection.

However, more research is still needed to determine whether the Miao strain is more infectious, more lethal or more resistant to vaccines and treatments than other mutant strains.” according to a report in the U.S.

Capitol Hill on September 7 local time, Novel coronavirus pneumonia cases increased sharply in novel coronavirus pneumonia cases compared with the labor day in 2020.

The number of confirmed cases, deaths and hospitalization in the United States increased sharply over the last day of the Labor Day holiday in September 6th.

The number of confirmed cases of novel coronavirus pneumonia increased by 316%.

The Washington Post reported that novel coronavirus pneumonia was the highest in 2021, compared with 38192 in 2020, compared with last year, and the number of deaths due to novel coronavirus pneumonia was two times higher than that in 2020.

Novel coronavirus pneumonia novel coronavirus pneumonia has increased sharply.

Statistics released by Johns Hopkins University of the United States show that as of 23:59 Beijing time, the new cases in the US have eased up during the peak period, but still continue to exceed 100 thousand cases.

At present, there are more than 40 million 20 thousand cases of novel coronavirus pneumonia confirmed in the report, and over 649 thousand patients died in September 7th.

The Miao strain has spread to more than 40 countries and regions around the world.

The global epidemic weekly report released by the World Health Organization on August 31 said that the who named the novel coronavirus variant virus b.1.621 as the “Miao” strain and listed it as the variant strain that “needs attention”.

According to the global epidemic weekly report, the Miao strain was first found in Colombia in January this year.

The mutant strain may have high vaccine tolerance and can escape the immunity brought by previous infection or vaccination.

Therefore, the who will further monitor it.

The Ministry of health of Columbia also confirmed in September 2nd that “Mutu”, a variant of COVID-19, is a local variant strain found in the country.

Diego Alvarez, a researcher at the National Institute of health of Colombia: the strain appeared in Colombia in January this year and has now spread to 43 countries and regions around the world.

The Colombian health department said that at present, about 39% of the existing confirmed cases in Colombia are infected with the mutant strain, and nearly 60% of the deaths during the past epidemic peak were related to the mutant strain.

Relevant monitoring shows that the global prevalence and infection rate of Miao variant virus has decreased, but it is still at a high level in Colombia and neighboring Ecuador.

  In addition to South America, Miao strain was also reported in Japan and South Korea in Asia.

Japan’s Ministry of health and labour in September 1st confirmed that in September 1st and June this year, 2 people infected with the virus at Airport Quarantine were infected with the novel coronavirus mutation virus “Miao virus strain”.

This is the first confirmed infection of this type of mutant in Japan.

South Korea’s central epidemic prevention strategy headquarters announced on September 3 that up to now, South Korea has reported 3 newly confirmed cases infected with the “Miao” variant strain, all of which are imported from abroad, and no community infection cases of the strain have been found.

What’s the difference with delta strain? What does it mean for who to list the new mutant strain “Miao” as “needing attention”? What’s the difference between it and the popular delta strain? Let’s get to know again.

According to WHO standards, the “need to pay attention to” variant means that the variant has genetic mutations that can affect the ability of virus transmission, symptom severity and immune escape; The “concern” variant means that the variant can reduce the effectiveness of public health strategies, vaccines or therapies.

According to WHO standards, if the spread of “need to pay attention to” mutant viruses is further accelerated to a certain extent, such as the need to adjust existing epidemic prevention measures, they will be upgraded to “need to pay attention to” mutant viruses.

According to the global epidemic weekly report released by the World Health Organization at the end of August, Miao strain is listed as a “need to pay attention” variant, which is lower than the “need to pay attention” variant of delta strain.

The latest research of who shows that there are a series of mutations in the “Miao” mutant strain, which has the potential characteristics of immune escape.

It has similar characteristics with the two mutant strains previously found in the UK and South Africa, which will weaken the effectiveness of the antibody.

Who has identified 5 novel coronavirus pneumonia variants since the outbreak of the novel coronavirus strain.

In order to facilitate public discussion and prevent stigmatization of discovery, who decided to name the COVID-19 variant in May of this year.

According to the official website of who, “Miao” is the fifth “need to pay attention” variant listed by who, and the other four include ETA, iota, kappa and lambda.

Among them, ramda strain was first discovered in Peru, South America, in December last year.

In June this year, the World Health Organization issued the Greek alphabet λ (ramda) named it and listed it as a mutant that needs attention.

Who reported in June that there were multiple mutations in the spike protein of ramda strain, which may lead to its stronger transmission and ability to resist neutralizing antibodies than the original strain.

  In addition, the World Health Organization now lists 4 variants of COVID-19 as a variety of “needs to be concerned”: first discovered in Britain, Alfa (Alpha), Berta (Beta) discovered in South Africa, Gamma discovered in Brazil, and Delta discovered in India.

The Centers for Disease Control and prevention of the United States said that the high infectivity of delta virus strain is equivalent to that of chickenpox virus, and is stronger than that of SARS virus, smallpox virus, seasonal influenza and other viruses.

In fact, there are also some variants of COVID-19 that are not yet listed in the who’s “need to pay attention” or “need to pay attention” list because they are not level enough.

British scientists recently released a research report.

After studying the existing COVID-19 mutant strain and its evolutionary pathway, it is found that there may be a higher rate of COVID-19 mutation in the future, and the mortality rate may be as high as 35%.

In addition, the report also predicts the possibility of another mutation, that is, the virus becomes more infectious but less toxic, and infected people will have symptoms similar to the “common cold”.

  As early as June this year, who director general Tan Desai said that new mutant strains will appear in the future and the virus will “evolve”, but the emergence of new mutant strains can be prevented by curbing the spread of the virus.

Therefore, strict epidemic prevention measures must be implemented and novel coronavirus vaccines must be actively planted at the same time…
