A senior health expert has stated that the large frequency of Omicron BA.2 cases reported in India is no reason for alarm since it would not result in another Covid-19 outbreak in the nation.
Dr Rajeev Jayadevan, Co-Chairman of the National IMA Covid Task Force, told ANI that BA.2 is a sub-lineage of the Omicron variety, which fueled the nation's 3rd phase.
BA.2 cannot infect persons who have earlier had the BA.1 sub-variant of Covid-19, as per his belief.
It will not produce another spike, according to Dr Jayadevan. BA.2 cannot infect persons who have already been infected with BA.1. This isn't a brand-new virus or strain. BA.2 is an Omicron sub-lineage.
BA.2 would be more transmittable than BA.1, according to the specialist, and it has mutated to boost its risk of transmission.
According to him, BA.2 is somewhat more transmissible than BA.1. It has been continually evolving over the previous two years to improve its fitness, or its capacity to infect more individuals and overcome natural and vaccine immunity.
Dr Jayadevan further stated that the Omicron variation demonstrated how vaccination immunity may be readily overcome by variants and that this pattern would continue for the foreseeable future if new variants develop after viral mutation.
He made the observation. Even vaccination protection may be readily exceeded by mutations, as Omicron shows, and this tendency is predicted to continue as new variants emerge. However, BA.2 and BA.1 both have immunological escape capabilities, which indicates that this virus could infect us even if we've been organically contaminated, vaccinated, or both.
BA.2 is a sub-lineage of Omicron, according to Dr Jayadevan, and is fundamentally the same as Omicron, which was discovered in November in South Africa. BA.1, BA.2, and BA.3 are now available.
He also predicted that the virus will persist for a long period.
Viruses will continue to exist. For a long time, it will be in ups and downs. There will be a rise when the next variety is released. They don't know when it will happen, but history indicates that it would happen once every 6 to 8 months, and that is how it usually behaves.
He went on to say that until then, we're in the Omicron low phase. However, we must keep in mind that this virus is still present, which implies we must do all possible to prevent it from infecting us.
According to Dr Jayadevan, BA.2 might induce severe lung damage in hamsters in Japan, according to research.
As of now, the signs of Omicron are the same for BA.1 and BA.2. As a result, there is no distinction in severity. However, research on hamsters was conducted in Japan. BA.2 was shown to be more engaged in the lungs than BA.1 in this investigation of hamsters.
On the worldwide trend of Omicron BA.2 cases, he stated that BA.2 is considered to be on the rise in India. However, the incidence is progressively expanding in various other Asian nations in the area and beyond Europe, notably in Denmark. In both the United Kingdom and the United States, there is a modest rise.
