American health experts have raised alarm bells about the BA.2 Omicron sub-variant of the corona virus. In Europe and many countries of Asia including China, Hong Kong, the fresh wave came only because of BA.2. Many US experts have said about this highly infectious sub-variant of Omicron that it could become the cause of the next wave. However, US health officials have expressed hope that there will not be much jump in corona cases from BA.2. The reasoning behind this is that last year a lot of people had been infected with the original Omicron, the vaccination has also happened, so they will have immunity from serious disease. Nevertheless, experts have enumerated some reasons due to which the wave of BA.2 can prove to be fatal. At the same time, scientists of the World Health Organization (WHO) have reported that mutations have been detected in oomicron variants at many places, which makes it more It is also dangerous and contagious.It has been named the XE strain.
Why can BA.2 Omicron wreak havoc in America?
Less than 70% of Americans over the age of 65 have received the first booster shot, meaning the larger population is at risk. Dr. Eric Topol, Professor of Molecular Medicine at a research institute in California, put forward this fact in a conversation with the NY Times. Many people who got a booster shot in the midst of dwindling immunity, their immunity must have started decreasing now. Those who rely on natural immunity should be more careful than BA.2 Omicron as it can easily penetrate it. There is also a danger of being careless because people are tired of following masks and social distancing for almost two and a half years.
Booster dose for every adult
While the BA.2 variant of Omicron is at risk, another variant named XE has arrived. It is said to be 10 times more infectious than BA.2. Looking at the new variants, there is a need to speed up the booster dose. Meanwhile, the Centre-affiliated body ICMR says that booster doses of Kovid vaccines should be given to all adults, as the antibodies produced in the body from two doses decrease significantly after eight months. The organization also says that if two different doses are taken, then the immunity formed from it is more effective.
Corona’s new strain is more dangerous than Omicron: WHO
According to the World Health Organization, a new XE variant of Omicron has arrived, which is 10 times more infectious than BA.2. However, this claim needs further confirmation. This variant is composed of two subline ages BA.1 and BA.2 of Omicron. It was first detected in Britain on 19 January, the WHO said in a report released earlier this week. Since then more than 600 cases of this variant have been found. This variant has also been found in France, Denmark and Belgium.
