The rise, though gradual, in Covid-19 cases in Telangana is still being driven by the BA.2, a sub-variant of Omicron.
INSACOG also said none of those variants has shown either increased transmission, locally or otherwise, nor were they associated with severe disease or hospitalisation.
A 21-year-old from Kollam is suspected to have been infected with Covid XE, the mutant variant of the novel coronavirus, trigerring worries.
Two new SARS-CoV-2 mutants, BA.2.10 and BA.2.12, related to the Omicron sub-variant BA.2, have been found in Bengaluru, by INSACOG attached labs.
“The Tamil Nadu government is cautious about the new variant of Omicron XE but prepared to face any eventuality,” Health Minister Ma Subramanian said on Tuesday.

Director of Institute of Life Sciences Dr Ajay Parida said the State government has been asked to send all positive samples for sequencing.
The UK Health Security Agency is studying XE, a mutation of the BA.1 and BA.2 Omicron strains and as of March 22, 637 XE cases had been detected in England, according to official figures.
However, Dr Jacob John, former professor at CMC Vellore, and renowned virologist, says the chance of another variant in India is highly unlikely.
China reported another 397 cases of local transmission nationwide on Friday, 98 of them in Jilin province that surrounds Changchun.
Meanwhile, the State recorded 1,480 positive cases, including 334 of the 0-18 years age group, in the last 24 hours taking the overall tally to 12,73,003.
This is because of a phenomenon called ‘epistasis’, where the background of mutations influences how genes actually work.
The UK Health Security Agency (UKHSA) said that BA.2 has an increased growth rate compared to BA.1 in all regions of England where there are enough cases to assess it.
Elaborating further on the virus spread, he said those who recovered from Omicron will have antibodies for three months and then they should get a booster dose of vaccine.
The number of active cases on Friday rose to 1,13,300 with Guntur taking the lead 12,315. West Godavari has the lowest of 3,888 active cases.
