United States of America. XBB.1.5 is the “most infectious” variant of the coronavirus

The XBB.1.5 variant is a descendant of XBB. It was created as a result of the exchange of genetic material of representatives of two sublines BA.2. It has a new mutation, F486P, which is “boosted,” allowing the virus to attach more easily to the ACE2 receptors in our bodies. According to the researchers, this could make XBB.1.5 more effective at infecting than the original, he says from the inside.

This information was confirmed by the World Health Organization (Who is the). It considered XBB.1.5 to be the “most infectious” variant of Omicron. It accounts for more than 70% of COVID-19 cases in the Northeast United States of America (in New YorkConnecticut, New Jersey, and Massachusetts), the daily reported Washington Post.

Its incidence increased by just 2 percent. Cases in early December increased to more than 27 percent. In the first week of January, the US Centers for Control and Prevention estimates diseases. “Right now, the virus is spreading rapidly,” said Andy Rothstein, a computational biologist. “The number of cases is doubling week after week,” he added.

New Omicron XBB.1.5 sub-variant “evolved because humans were infected with multiple viruses”

XBB.1.5 does not appear to be more effective at avoiding antibodies than its predecessors, virologists comment. Therefore, the authorities are calling for a vaccine against sub-variants Omicron.

“The vaccine protects against the XBB variant well in terms of hospitalizations and deaths, although it probably doesn’t do much to prevent infection,” said Dr. John Schwartzberg, an infectious disease expert and professor emeritus at UC Berkeley College. public health, the insider said. – Stay up to date on vaccinations (both influenza and COVID-19) – he added.

– XBB did not evolve because humans were vaccinated. Let’s be honest, it evolved because humans were infected with many viruses At the same time, said von Cooper, professor of evolutionary biology at the University of Pittsburgh.
