Important information has come to the fore regarding the genome sequencing of the coronavirus. Scientists have revealed that so far 230 forms of coronavirus have been confirmed in the country. Not all of these mutations are harmful to humans, but many serious mutations can also cause harm. One of these serious variants has spread across the country. Till some time back, there were two variants of Delta but now another variant has also been found which is named AY3.
India is the second country after America where three mutations of Delta have been found. The Insacog, which monitors genome sequencing, issued an alert to the states, saying that the cases of AY3 variants are still very less but studies are going on on it. A group of scientists is monitoring it. At present, not much information can be given about this variant.
Scientists told that a third mutation has also happened in the delta variant. This mutation occurred as ORF1A: I3731V with S: K417 in a supporting role. Hence it is named AY3. For the time being, it can also be considered in the serious category like Delta.
According to the data, more than 43.80 crore samples have been tested in the country so far, but out of these, only 42869 samples have been sequenced by scientists because most states do not even have genome sequencing labs. In the sequencing of these 42869 samples, scientists have found 230 forms of coronavirus, of which the highest delta variant is being found in May, June, and now in July. Out of these 230, 14 variants have been kept in the severe category. While eight variants have been considered a matter of concern. The Delta and Delta Plus variants have been kept in the critical category by the Government of India.
Delta Plus is not like Delta
Insacog has issued a statement that so far Delta Plus ie AY1 and AY2 mutations have been reported from the delta variant, with more than 80 cases reported. Both these mutations are currently under study and preliminary results suggest that AY1 and AY2 do not spread as rapidly as Delta. The relationship of both these mutations to lowering antibodies is not yet known.
AY3 could be a different variant
A senior scientist at IGIB based in New Delhi said that another mutation has also occurred in the delta variant. Its identity has been kept confidential for the time being as we do not have much evidence. The AY 3 may be different from the other two Delta Plus and AY 2 variants but will have to wait till the study is completed.
Delta Plus did not increase in Maharashtra, Madhya Pradesh, and Tamil Nadu
The committee said in a statement that Delta AY.1 and AY.2 cases have been declining over the past week. Earlier, most of these variants were being found in America and Britain, but now there has been a decrease in new cases. So far less than one percent of the cases have been found in India. All these cases came to the fore in the month of June. AY.1 and AY.2 mutations have not been found to be more aggressive than delta. Their cases have not increased in Ratnagiri and Jalgaon in Maharashtra, Bhopal in Madhya Pradesh, and Chennai in Tamil Nadu.
Delta Plus Not Contagious
New Delhi. The delta plus variant of the coronavirus is no more contagious than the delta variant. A government panel of the Indian SARS-CoV-2 Genomics Consortium (INSACOG) has reported that the cases of Delta's subgenera AY.1 and AY.2 are declining worldwide. By the end of June, its cases had dropped to zero in the US and UK where it was spreading most rapidly. In India, in June, its genome sequencing cases were reduced to less than one percent. On this basis, it can be said that this form of the virus is not more contagious.
