The latest on a variant of Covid-19 is rapidly advancing through the US data from the Centers for Disease Control and Prevention shows that NB.1.8.1 has begun to replace other circulating stretches of the coronavirus.
According to the latest of the CDC NowCastCovering the last two weeks until June 7, NB.1.8.1 is likely to cause 37% of all Covid-19 cases in the United States, barely behind the current dominant variant, LP.8.1 (38%). It is an estimate, but the CDC numbers indicate a large growth in NB.1.8.1 -Cases since last month, when officials first detected it in the country. Although not sure, it is possible that NB.1.8.1 could drive a renewed top of Covid-19 this summer.
The World Health Organization first recognized NB.1.8.1 as a variant worthy monitoring in mid -May, although it was initially detected in late January. Since then, it has become a growing threat. From early June, about a quarter of all global cases are thought to be NB.1.8.1, according to Which data. Covid-19 activity in general was also Rising In some regions of the world, and NB.1.8.1 was Attached to recent waves of cases and hospitalizations in some parts of Asia, including China.
So far in the United States, however, the situation does not seem drastically worse. The Covid-19 Test Positive Index Late week There is 3%, just a tick over the previous week. Hospitalizations and deaths related to Covid-19 have also left constant and low. And NB.1.8.1 does not seem to cause more severe disease on average than other circulating variants. Today’s variants still belong to the Omicron Treasury of the Virus, which means they have not changed much on genetic level and updated vaccine accelerators are still expected to be effective against NB.1.8.1.
At the same time, NB.1.8.1 It may be quite different than other stresses that it can become the dominant variant to move forward; Some early evidence suggests that NB.1.8.1 possesses mutations that could increase its transmissionability. This past winter was also unusually quiet for Covid-19, with low circulation in the United States and elsewhere, but that may set the stage for a larger peak this summer, experts warned.
“We do not foresee the NB.1.8.1 variant to present a greater risk of public health than other omikronous-descending variants, nor are we expect a major impact on vaccine efficiency against severe disease,” said Edoardo Colzani, head of the respiratory viruses at the European Center for Sick Prevention and Control, in A Statement released over the weekend. “However, after winter with a low circulation of SARS-Cov-2, the immunity of the population against SARS-Cov-2 may have partially decreased-partly between older adults and other individuals who have a higher risk of severe disease-growing vulnerability as virus activity rises.”
Thanks to vaccination and population immunity, the danger of Covid-19 has greatly diminished over time. But this summer could certainly give an inconvenient reminder of the misery it can cause.
