Ómicron's new BA.2.75 subvariant sets off alarms

The times of pandemic are far from disappearing, because the virus continues to mutate until it is perfected, and this time there is already a new variant that worries experts

The times of Covid19 continue and the virus continues to mutate until perfected, and now there is an Omicron variant known as BA.2.75 , which was detected for the first time in India just a few days ago; this has generated a lot of concern both in health experts and in the general population, so once again the alarms are going off.

This second-generation sub-variant of Omicron BA.2 has, according to Indian scientists , a growth of 18 percent over other sub-variants of Omicron currently circulating in said place, as reported by The Indian Express . These Omicron sub-lineages are the dominant strains that have circulated throughout the world with new mutations that have been constantly evolving.

BA.2.75 has been detected in 10 states in India , which has witnessed first-hand the increase in these new infections in the last 30 days. Recently there has been an increase in cases between 15,000 and 19,000 in the last 10 days, and in recent months it was below 3,000.

Scientists from other parts of India in collaboration with Dr. Rajesh Karyakarte have collected three sub-variants, BA.2.74, BA.2.75 and BA.2.76 , which are possible drivers of the current increase that has been experienced. These three subvariants have more than 9 spike protein changes, and it is believed that they may outnumber subvariants BA.4 and BA.5,

One of the reasons for concern about this variant is the G446S mutation, which experimentally is known to elude immune neutralization, Oscar Cingolani, professor of Medicine and director of the Center for Arterial Hypertension and the Critical Care Unit, published on his Twitter account ( UCC) Cardiovascular of Johns Hopkins Hospital.

For its part, India has not been the only place that has reported this strain, as there are also other countries such as Japan, Germany, the United Kingdom, Canada, the USA, Australia and New Zealand, according to data from Nextstrain. The good news is that there is currently no evidence that this new variant leads to a more severe form of the infection; however, things can change from one moment to another.

Although there is not much information about the new strain, there is already concern on the part of health experts, since Dr. Shay Fleishon, from the Central Virology Laboratory of the Sheba Medical Center in Israel, declared that this new subvariant could be "alarming because it may imply a trend to come.”
