Total 7,361 samples were sent for sequencing from Delhi in several months since Indian Sars-CoV-2 Genomics Consortium (INSACOG) was set up. As per data, of total 7,361 samples, delta variant was detected in 2,873 samples (39.03 percent).

Genome sequencing data revealed that delta variant was detected in 99 per cent of the sample in October, 97 percent in September, 86 percent in August and 52 percent in July. In the months of April and May, when the second wave of Covid was at its peak, 54 and 82 percent of total samples sent for sequencing were respectively detected with the delta variant.

In the months of June and July 90 percent and 52 percent samples were detected with delta variants. Of 6,235 samples that were sent to the National Centre for Disease Control (NCDC), the delta variant was detected in 2,268. Delta variants were detected in 531 from 1,027 sent to Institute of Liver and Biliary Sciences (ILBS) for genome sequencing.

Of 99 samples sent to Lok Nayak Hospital, 74 were detected with the delta variant. Alpha variants were detected in only 966 samples. Sources said that delta variant was found in almost half the samples, followed by AY.4 sublineage. Meanwhile, Delhi’s sixth sero survey report has revealed 90 per cent people in the national capital have developed antibodies against the coronavirus.
