The WHO has just released its new list of variants of the Corona virus, and it contains a new one. It's called XBB.1.5 and it's a descendent of the Omicron variant. While it's not considered a concern yet in the UK, it could evade COVID-19 vaccine boosters, and it has a better ability to get into cells.
XBB.1.5 is a descendent of Omicron
Omicron, one of the SARS-CoV-2 descendants, is a virus that has become highly transmissible. It was first detected in Botswana in 2021. As the virus becomes more virulent, scientists on this side of the Atlantic are watching for new variants.
New data suggests the Omicron sublineage is the origin of the latest COVID-19 variant. The variant's mutations allow the virus to better infect cells, evade immune defenses and lead to a higher chance of reinfection.
In addition to spreading to many countries, including Australia and the Philippines, the variant is also gaining traction in parts of Asia. In Singapore, the variant quickly spread and caused a surge in cases. This has prompted public health authorities to concentrate on keeping the sub-variant from entering the country.
The US Centers for Disease Control has been sharing data on Covid-19 infections. The rise of the COVID-19 variant coincides with a dramatic increase in hospitalizations. But the Department of Health does not believe it is making people sicker than other versions of the omicron.
It has better ability to get into cells
If you've been reading the news, chances are you've heard about a new variant of the COVID-19 virus. This new omicron variant is being studied by scientists as it spreads rapidly throughout the US. It appears to be more infectious than other variants and may be more likely to cause hospitalizations.
Several factors are contributing to its rapid spread, including its ability to evade immune protection. A key mutation has been identified, which could give the virus a significant boost in its ability to enter human cells. Researchers are studying how the mutation changes the virus's abilities to bind with certain cells.
Another mutation, called F486P, is believed to enhance the virus's ability to bind with human cell receptors. These binders are used by current vaccine-induced antibodies to neutralize the virus. However, the XBB.1.5 variant's binding affinity is much higher.
Some experts say this is a potential advantage over other omicron variants, which have more difficulty getting into humans. But other researchers say the variant is much more transmissible and thus poses a bigger threat.
It could evade COVID-19 vaccine boosters
The Centers for Disease Control and Prevention is tracking a new corona variant that is proving to be highly contagious. Scientists are worried it could become a major cause of new infections, especially in the Northeast.
It's known as the XBB.1.5 sub-variant, and it's one of several Omicron variants that have risen to prominence in the US. These variants are often immune-evasive, meaning they can evade the body's natural defenses. A mutation may allow the virus to evade a vaccine booster, or an antibody produced by a previous infection.
Some health experts worry that the XBB.1.5 variant may be more virulent than other omicron variants. But they also note that the disease hasn't yet reached levels of severeness that would make it a real concern. They say the number of infections is still low, and that the rate of hospitalization is lower than for other omicron variants.
Dr David Ho, a professor of microbiology at Columbia University, believes that XBB.1.5 is more transmissible because it binds better to cells than other variants. However, he also said that the mutations that allow the virus to evade immunity can also allow it to evade boosters, which can help it to spread.
It's not currently a variant of concern in the UK
A new variant of the SARS-CoV-2 virus called XBB.1.5 is spreading quickly in the US. According to reports, the number of cases has doubled in one week. Previously, it had only been found in New York state.
But this new Covid variant has been spotted in several other countries as well. One of the variant's mutations, known as the F486P mutation, helps the virus to evade immune protection, allowing the virus to infect more people. It also improves its ability to bind to cells.
However, a recent report by the World Health Organization says XBB.1.5 is the most transmissible subvariant of the virus so far. This means it could be a key factor in a wave of illness in other countries.
In the UK, there is no evidence to suggest that the new variant is causing more severe illnesses than other circulating variants. Yet, experts are predicting that the virus will spread in other parts of the world.
