U.S. exceeds 1000 cases: COVID-19 Lambda variant is more infectious?

U.S. exceeds 1000 cases: COVID-19 Lambda variant is more infectious?  “Delta” is not broken “Lambda” is coming again, mutant strains swept the United States, more than a thousand people infected, more infectious?

According to CNN, with the spread of the COVID-19 epidemic, there have been cases of infection with the “lambda” strain in the United States. This mutant strain was first discovered in Peru in August last year. At present, 1,060 cases caused by the “lamda” strain have been found in the United States, and the Japanese government has also reported it.

United States: Over 1,000 cases of “Lambda” strain infection

According to reports, although the number of confirmed cases of COVID-19 pneumonia infected with the “lambda” strain in the United States is much less than the number of cases infected with the delta mutant strain, some infectious disease experts say that the “lambda” strain is also They are paying close attention to a mutant strain. Marani, an expert at the American Academy of Infectious Diseases, said that it is still difficult to determine how infectious this strain is.

Japan’s Ministry of Health, Labour and Welfare also reported a few days ago that the country’s first confirmed case of COVID-19 pneumonia infected with the “lamda” strain. It is reported that on July 20, the infected person flew from Peru to Japan’s Haneda Airport and was diagnosed with COVID-19 pneumonia during entry quarantine. After genetic analysis, it was determined that the infection was the “lambda” mutant strain. The Ministry of Health, Labour and Welfare stated that it is still analyzing the variant strain.

In addition to the United States and Japan, according to the data of the WHO in July this year: Since it was first discovered in Peru in August last year, the “lamda” strain has appeared in about 30 countries and regions, especially in Chile, Peru, The spread of South American countries such as Ecuador has accelerated significantly. Among them, Chile has the largest number of infections with this strain, accounting for 31% of the total number of such cases in the WHO’s control. Data from the Public Health Agency of England in July this year also showed that in addition to South America, countries and regions such as the United States, Canada, Germany, Spain, Israel, the United Kingdom, and Zimbabwe have also reported cases of infection with the “lambda” strain.

WHO: “Lambda” is one of the mutant viruses “needs attention”

The “Lambda” strain is spreading in many places around the world. How did the name “Lambda” come from, and how infectious is it?

The World Health Organization issued a report on June 14 this year, naming the C.37 strain first discovered in Peru with the Greek letter λ (lambda), and listed it as one of the mutant viruses that “need attention”. According to WHO’s standards, if the spread of mutant viruses that “need attention” further accelerates and becomes serious to a certain extent, if existing epidemic prevention measures need to be adjusted for this, they will be upgraded to mutant viruses that “need attention”.

According to the report, there are several genetic mutations in the spike protein of the “lambda” strain, which are potentially more infectious and more resistant to neutralizing antibodies. However, the evidence currently available is not sufficient to confirm all Influence of these mutations. For this strain, further research is needed to determine the necessary countermeasures.
