The Centers for Disease Control and Prevention Center found a new case. covid-19 Transformation nb.1.8.1 related to the surge in China’s viruses.
According to a record uploaded by CDC’s airport test partner, Ginkgo Bioworks, the case associated with the NB.1.8.1 deformation reported that it arrived at the airport in California, Washington, Virginia and New York City.
For more information on sequencing results Published Recently, global initiatives for GISAID or all influenza data sharing, the virus database shows events from many countries, including Japan, Korea, France, Thailand, the Netherlands, Spain, Vietnam, China and Taiwan. Travelers tested from April 22 to May 12.
NB.1.8.1 cases are now reported separately from the airport case by other weekly health authorities, including Ohio, Road Island and Hawaii. The fastest incident in California and Washington dates back to late March and early April.
There was an expert Look closely This variation is now dominant in China and is increasing in some of Asia. The Hong Kong authorities say that the ratio of covid-19 in the city has risen to the worst level for at least one year after “significant increase” in the emergency room visits and hospitalization led by Covid-19.
A CDC spokesman said in a statement that “CDC knows the reported cases of Covid-19 nb.1.8.1 in China and is in contact with international partners regularly.”
The spokesman said that there have been too few US sequences about the agency’s NB.1.8.1. Modification dashboard.
Hong Kong authorities say There is no evidence that the virus, the descendant of the virus’s XDV genealogy, is more serious, and the residents have begun to be hidden when public transportation or crowded places go up.
There is a health authority in Taiwan Also reported Emergency room visits, serious events and deaths. Regional health authorities say they are reserved for vaccines and antiviruses in response to infectious diseases.
Preliminary data Researchers in China suggest that the NB.1.8.1 deformation is not better to avoid the immune system compared to other strains, but it suggests that it is possible to transfer more because of its higher ability to combine human cells.
“More predictable patterns”
Tensions appeared several times on Thursday meeting In the case of an external vaccine torture of the Food and Drug Administration, Update Covid-19 vaccines in the coming autumn and winter season.
vaccine Last season It targeted the descendant of JN.1 deformation called kp.2. The initial data presented to Pfiza and Moderna Scholarship has proposed to switch to other JN.1 descendants called LP.8.1 in recent months.
“LP.8.1 vaccine has the highest tasks for LP.8.1, which is dominant in many regions and many other regions in many Asian countries, dominated in many other areas, including NB.1.8.1, cross -neutralize other transformations that are currently circulating.”
The committee said that the vaccine in the upcoming season should aim for any kind of JN.1 transformation, but it was unanimously supported by the details. Some have allowed vaccine manufacturers to adhere to the vaccine last season, while others demanded updates for Pfizers and Moderna to aim for the descendants of JN.1’s LP.8.1 as a prototype.
Jerry Weir, vice president of Viral Products of the FDA, said, “I can’t predict evolution and I don’t know how it will be diversified, but the overwhelming probability that it will come out of the cycle now in the next six months and next year is overwhelming.
Currently, CDC and FDA officials say that only one strain, the XFC, is growing in the United States, but warns that the evolution of the virus is unpredictable even if it is settled in two soaring patterns in summer and winter.
Last season, unlike the types of substitute substitutes driven by highly mutated strains in some of the early days, I saw an evolutionary “drift” in the virus. While the Covid-19 trend rose during the winter, they were much lower than before.
Natalie Thornburg of CDC said, “Throughout this winter, we haven’t seen the tension replacement we have for the past few years, but I don’t say the virus will not be shifted in the future.” Thornburg is the acting officer of the Corona virus and other respiratory viruses of the CDC.
The proportion of Covid-19 is now lowered to a low level nationwide. Emergency room visit and Wastewater test.
Thornburg said, “After five years, we think we are seeing a very distinct pattern that falls into more predictable patterns.
