A new form of covid BA.4.6. It is spreading rapidly around the world.
This variant spreads faster than other variants of Omicron.
The only remedy for its prevention is the vaccination of “booster dose”.
London: BA.4.6nature of COVID Omron new form of . Rapidly spreading in America. Now it has also been confirmed to spread in the UK. The UK Health Protection Agency’s (UKSHA) new briefing document on COVID variants mentions that in the week starting 14 August, BA.4.6 Variants The UK accounted for 3.3% of cases. But a recent investigation has shown that it accounts for 9% of UK Covid cases with BA.4.6. has been responsible. Similarly, according to the Centers for Disease Control and Prevention, BA.4.6 now accounts for more than 9% of recent cases across the United States. This variant has also been identified in many other countries of the world. So should we worry about the BA.4.6 variant? Let’s take a look at the information so far…
BA.4.6 Omicron has the same form as BA.4. BA.4 for the first time in January 2022 South Africa and since then it has spread all over the world with the BA.5 version. It is not entirely clear how BA.4.6 emerged, but it is possible that it may be a recombinant variant. Recombination occurs when two different types of SARS-CoV-2 (the virus that causes COVID-19) infect the same person at the same time.
While BA.4.6 will be similar to BA.4 in many ways, it carries mutations in the spike protein, a protein on the surface of the virus that allows it to enter our cells. This mutation, R346T, has been seen in other variants and it protects the virus from the person’s immunity. In other words, it helps the virus to evade the antibodies obtained from vaccination and prior infection.
Severity, infectivity and immune evasion
Luckily Omicron wasn’t very destructive, but Omicron’s sub-variants spread very quickly. BA.4.6 suppresses the immunity power of the body. According to a UKHSA report, BA.4.6 spreads much faster than BA.5 in its initial period. At the same time, according to a report by Oxford University, people who have taken Pfizer dosage to protect against Kovid, their antibodies do not have an effect on BA.4.6. Which is a matter of concern. However, to avoid BA.4.6, a booster dose can be quite successful. Since the details of this new variant are not yet fully known, for the time being we can only rely on the booster dose.
Vaccination is important
The rise of BA.4.6 and other new variants is a matter of concern. Their new appearance shows that the virus is still with us, and is trying to penetrate our body in a new way by breaking the immunity we got from vaccination.
But vaccination Provides good protection against critical illness. It is still the best weapon to fight against COVID. bivalent booster The recent approval is good news for us. In addition, developing multicomponent coronavirus vaccines that target multiple variants may provide more lasting protection.
A recent study showed that through the nose A multicomponent coronavirus vaccine taken from the U.S. has proved to be more effective on the original form of Kovid and its two other forms. The new variants, including BA.4.6, are being closely monitored, as they may cause the next wave of the COVID pandemic. To the public… to prevent the spread of a very contagious virus must be vigilant and follow any public covid rules.
