Covid-19: situation worsens in America due to new variant XBB.1.5, its confirmed in India too, its seriousness more

A new sub-variant of Omicron is wreaking havoc in the US amidst the deteriorating situation due to the BF.7 variant of Omicron in China-Japan. According to data published on Friday by the Centers for Disease Control and Prevention, Omicron’s XBB.1.5 variant has increased the difficulties in the US. At present, this sub-variant is considered to be the main reason for more than 40 percent of the corona cases in America at this time. Compared to last week, cases of infection due to this variant have increased by two times. Scientists say that this may be more problematic than all the sub-variants of Omicron so far.

Meanwhile, the first case of infection with the XBB.1.5 variant has also been confirmed in India. According to the report of the Indian SARS-CoV-2 Genomics Consortium (INSACOG), the first case due to this new variant has been reported in Gujarat. The way the situation has been seen deteriorating in New York due to this, in view of this danger, India also needs to take special precautions. Let us understand about this variant in further detail.

Know about XBB.1.5 variant

There are reports of the situation worsening due to the infection of the XBB.1.5 variant in many parts of the US. Scientists have found in preliminary studies that it originated from a new mutation in the XBB sub-variant, the nature of which is of concern in many cases. Virologist Andrew Pekoz at Johns Hopkins University explains that XBB.1.5 is different from other members of its family. This is because an additional mutation is being observed that may help it to better bind to cells.

Risk of serious diseases in case of infection

The virus’s ability to bind helps it infect people more easily, says virologist Andrew Pekoz. Reports from New York show that the rate of hospitalization of infected people has also increased here, which makes it clear that this sub-variant can not only kill people faster than other variants so far. Not only this, the risk of developing serious diseases is also high. The team of researchers found that XBB.1.5 is also more successful in evading the body’s immune system than other variants.

Scientists keep warning about mutation in XBB subvariant

The XBB subvariant was first observed in India, arising from a combination of two other subvariants. In the studies conducted on this, scientists had not only alerted about its seriousness and infectiousness, but also expressed the possibility of mutation in it. In a study published in the journal Cell earlier this month, scientists at Columbia University warned that mutations in the XBB-subvariant could further reduce the efficacy of COVID-19 vaccines, increasing the risk of infection as well as severe disease. There may also be an increase in danger.

What is the threat to India from this?

According to Covid reports, apart from one case in Gujarat, there is currently no confirmation of this variant from any other part of the country. Officials monitoring the cases of corona in Maharashtra say that there have been more than 275 cases of XBB subvariant here, although this new subvariant is yet to be confirmed. The way the situation has worsened due to infection in America, India also needs to be careful about this danger.

Health experts say, its effect should not be much in India because people here have been cured after getting infected by the XBB variant of the same family, as well as most of the people here have taken primary and booster doses. However, looking at its nature, it is very important to be strict about prevention from Covid.
