Up to now, many COVID-19 mutant viruses have appeared in the world, such as "Delta" that first appeared in India, "Alpha" that appeared in the United Kingdom, "Beta" that appeared in South Africa, and "Mu" that appeared in Colombia, etc. In the United States, a mutant virus called "Iota" appeared.
"Iota" is also known as the "B.1.526" variant strain. It was first discovered in New York in November 2020 and has now spread to 50 U.S. states, Puerto Rico, and Washington, D.C., as well as 27 countries and regions around the world. Related cases. Studies have shown that "Iota" is more infectious and immune escaped than any previously circulating mutant strain, and can also increase the mortality rate of infection in the elderly to 62% to 82%.
In addition to "Iota", the US Centers for Disease Control and Prevention is also paying attention to two new mutant strains, namely, "B.1.429" and "B.1.427". These two mutant strains first appeared in California.
St. Louis infectious disease physician Farrin Manian (Farrin Manian) said that the uncontrolled spread of the virus in the United States is a major factor in the production of new strains. The mutant viruses originally discovered in other countries may also develop further in the United States. As long as the virus continues to spread in the United States, we will see new strains emerge."
Melia also further pointed out that it is worth noting that in the United States, only a small part of the COVID-19 virus in patients has been genetically sequenced, which means that unless the mutated virus is widespread, it will often be ignored.
Mutated viruses are raging in the United States and are inseparable from the current situation of the United States in fighting the epidemic. The US media mentioned that a poll conducted by the Axios-Ipsos survey company showed that because some people have not been vaccinated against COVID-19, the COVID-19 virus has a chance to spread and mutate further. 55% of adults even said that even if they had a vaccine, they would not get it.
