New Delhi, April 24 : As the second Covid wave ravages India with a vengeance, the death rate is alarmingly growing and thousands of asymptomatic patients are fast transmitting the highly infectious strains which could put the entire nation to a halt sooner than expected if not controlled, experts warned on Saturday.
The threat of double and now a triple-mutant Indian strain, along with the deadly UK variant, are believed to be behind the latest surge across the country.

COVID-19: Some 11 per cent samples from across India show variants of concern (File)
New Delhi:
The UK strain is driving the Covid surge in Delhi, an analysis of samples has revealed. Data released by the National Centre for Disease Control (NCDC) says over 400 cases of the UK strain and 76 of the Indian double mutant were found in Delhi.
Some 11 per cent samples from across India show variants of concern .
A total of 1,644 cases of the UK strain have been found in India, 112 cases of the South African strain, one of the Brazilian strain and 732 cases of the double mutant that emerged in India.

The surge in Covid-19 cases in the national capital could be attributed to the UK variant of the SARS-COV-2 virus as genome sequencing of samples detected 400 cases of the strain.
Sujeet Kumar Singh, Director of the National Centre for Disease Control, presented the findings at a webinar on ‘Genome Sequencing of the SARS-COV-19’ organised by the Indian Council of Medical Research.
Besides 400 cases of the UK strain, scientists also found 76 cases of the Indian double mutant in the national capital. Scientists had carried out genome sequencing of 3,208 samples in the national capital.
Singh said the UK variant of the coronavirus was found in 28% of samples in the second week of March, while it had risen to 50% of samples collected in the last week of March.

New Delhi: In the last 60 days, the B.1.617 lineage of the SARS-CoV-2 virus has sped ahead in the evolutionary arms race of the viral spread in India, leaving behind almost all other lineages circulating in India.
A lineage is defined by a set of genetic mutations that alter some of the amino acids (the building blocks of proteins) of the original virus.
