The positive cases of novel coronavirus infection are rising at an unprecedented rate around the world, even as we continue to decipher more about the highly infectious contagion. Scientists and medical experts globally are racking their brains to configure the genetic makeup of the virus and develop a vaccine for the same. As of now, more than 2 lakh 16 thousand coronavirus cases have been reported in India only, while the worldwide toll is inching towards the 7 million mark.
In recent research, scientists at the Centre for Cellular and Molecular Biology (Hyderabad) have identified a unique trait in the SARS-CoV-2 virus present in India. It is interesting to note that this trait is different from the one prevalent in different parts of the world.
According to the scientists, this distinct cluster of the virus population was found in 41 per cent of the genome analysis of SARS-CoV2 virus in the Indian samples. They named this particular trait as “Clade I/A3i”. It is important to note that globally only 3.5 per cent of the genomes submitted into the public domain has this unique trait. Scientists are speculating that this cluster may have originated from an outbreak in February 2020 and then spread throughout India.
“This cluster seems to have originated from an outbreak in February 2020, and spread through India. This comprises 41% of all SARS-CoV-2 genomes from Indian samples, and 3.5% of global genomes submitted into public domain,”
According to the reports The CCMB is a laboratory under the Council for Scientific and Industrial Research (CSIR) and it shared a link to a fresh preprint on genome analysis of SARS-CoV2 spread in India on Twitter. As of now, this unique trait of the virus is located largely in the southern states of Tamil Nadu and Telangana.
The report which was published in BioRxiv journal which is still under peer review, further stated that epidemiological assessments suggest that the common ancestor emerged in the month of February 2020 and possibly resulted in an outbreak followed by countrywide spread, as evidenced by the low divergence of the genomes from across the country.
