NEW DELHI : India will conduct genome sequencing to check for the emergence of new covid-19 strains for at least year, a government official said as the country started lifting most pandemic-related curbs amid falling cases.

Genome sequencing is a laboratory method to determine the entire genetic make-up of a specific organism or cell type. While many districts are reporting as few as 10-15 daily cases, several in Chhattisgarh and Madhya Pradesh are down to zero, prompting the government to decide against extending disaster management rules to curb covid.

Alongside, the government plans to open vaccine booster doses to all adults. A government official said that the positive cases being reported currently are mostly showing cycle threshold (CT) levels above than 25, which he said is a challenge in identifying a new variant.

Hence there is a need for continuous genome sequencing. In a cycle threshold, which is used for RT-PCR tests, the higher the value the lower the viral load (hence the challenge). “It is very comforting to us that lesser number of covid cases are coming, but we have to be vigilant to investigate new mutation of the virus.
