Increased affinity for particular demographic or clinical groups, such as children or immunocompromised individuals. By Katherine J. Wu. As genetic changes happen over time, the virus that causes COVID-19 begins to form genetic lineages. March 9, 2022. Prof David Heymann from the London School of Hygiene and Tropical Medicine acknowledged that there was still a fair amount to learn about this latest variant. Some changes and mutations allow the virus to spread more easily or make it resistant to treatments or vaccines. It is yet another offshoot of the globally-dominant Omicron Covid variant.Omicron has outperformed the earlier Alpha, Beta, Gamma and Delta coronavirus variants since emerging in late 2021. What's kraken? It's not clear why, but may be due to the effectiveness of the vaccines and boosters, previous infections, or mutations making these newer variants less virulent. A single copy of these materials may be reprinted for noncommercial personal use only. Numerous variants of the virus that causes COVID-19 are being tracked in the United States and globally during this pandemic. 34,679 cases reported in the United States per day, with only about 16% of those who are eligible, View which vaccines are available at each location, Choose outdoor activities over indoor activities whenever possible, Stay home if you're sick or have symptoms of COVID-19. Prof Wendy Barclay from Imperial College London said XBB.1.5 has a mutation known as F486P, which restores this ability to bind to cells while continuing to evade immunity. These boosters are designed to protect against disease caused by the original strain of the SARS-CoV-2 virus, as well as the Omicron subvariants BA.4 and BA.5 (although experts are still learning about their effectiveness against the latest Omicron subvariants). Pfizer, Moderna, and Johnson & Johnson all said their vaccines were effective in preventing severe disease and hospitalization in Alpha cases. Data has suggested that the original Omicron strain was less severe, in general, than previous variants, according to the CDC. Oops!

If you do that, then there isn't anything that isn't god, including this divine bod XBB had a mutation that helped it beat the body's immune defences, but this same quality also reduced its ability to infect human cells.
The Alpha and Omega of COVID-19: Yes, the Pandemic Will End (but Not The institute's Dr Ewan Harrison thinks XBB.1.5 probably emerged when someone got infected with two different Omicron types: "A bit of the genome from one virus gets joined up with another bit from a second virus, and they merge, and that goes on to transmit.". Prof Barclay said she was not especially concerned about the general UK population because there was "no indication" that XBB.1.5 would "break through" the protection against severe illness provided by vaccines.

Meanwhile, experts are still learning about several newer Omicron strains circulating in the U.S., each of which, as of mid-December, were causing less than 6% of infections. The Omicron variant (B.1.1.529) was first detected in specimens collected on Nov. 11, 2021, in Botswana.
