The Delta strain of coronavirus — a mutated variant of concern with high transmissibility and ability to trigger aggravated life-threatening symptoms in patients — was found to be the most prevalent mutant strain of
coronavirus in five of the worst Covid-hit Jharkhand districts during random sampling done from April 1 to June 9, officials said on Monday.
The health department sent 364 samples of Covid-19 patients randomly selected from five districts – Ranchi, Jamshedpur, Dhanbad, Hazaribag and Palamu – for Whole Genome Sequencing to the Institute of Life Sciences (ILS) in Bhubaneswar and the results showed that
at least 204 of the samples were infected by the Delta variant of coronavirus.
