The last Covid variable now leads to a third of the cases

The most recent of the Covid-19 switching is to quickly advance through American data from and prevention control centers that NB.1.8.1 has begun to replace other circulating strains in the Coronavorus virus.

According to the latest center of disease control NowocastThat covers the past two weeks until June 7, is likely to cause NB.1.8.1 37 % of all cases of Covid-19 in the United States, barely behind the current dominant alternative, LP.8.1 (38 %). It is an estimate, but the numbers of the Disease Control Center indicate a significant increase in cases of NB.1.8.1 since last month, when officials discovered for the first time in the country. Although it is uncertain, it is possible that NB.1.8.1 can lead a renewed peak of Covid-19 this summer.

The World Health Organization first realized NB.1.8.1 as a variable worth monitoring in mid -May, although it was initially discovered in late January. Since then, it has become an increasing threat. As of early June, it is believed that about a quarter of all international cases Global Health Organization. Covid-19 activity was generally also to rise In some regions of the world, and NB.1.8.1 Kan linked To the last tip of cases and hospitalization in parts of Asia, including China.

So far in the United States, the situation does not seem to get worse significantly. Covid-19 test rate from At the end of the week It is 3 %, just a sign above the previous week. Hospitals and deaths related to Covid-19 as well Remain Fixed and low. And NB.1.8.1 It does not seem to cause a more severe illness than other variables circulating. The variables today still belong to the virus’s Omkron ratios, which means that they have not changed significantly at the genetic level and the updated vaccine reinforcements are still expected to be effective against NB.1.8.1.

At the same time, NB.1.8.1 may be completely different from other strains that can become the dominant alternative to proceeding to the foot; Some early evidence indicates that NB.1.8.1 has mutations that can increase its transfer. This last winter was unusually calm for Covid-19, with a decrease in blood circulation in the United States and other places, but this road may pave the greatest summit this summer.

“We do not expect the NB.1.8.1 variable from other variables, and we do not expect a significant impact on the effectiveness of vaccines against severe diseases, at the Center’s breathing center at the European Center for Disease Prevention and Control of the disease, in the respiratory stage,” said Edardo Colkani, head of the respiratory virus unit at the European Center for Disease Prevention and Observer in the field of breathing. statement It was released during the weekend. “However, after the winter with a decrease in SARS-2, the population immunity may partially diminish the SARS-COV-2, especially among the older adults and other individuals who are at risk of severe diseases-dramatically with the high activity of the virus.”

Thanks to vaccination and population immunity, the risk of Covid-19 decreased significantly over time. But this summer can definitely provide an unwanted reminder to the misery that it can cause.
