CHENNAI : The random tests done on passengers arriving from 'non-risk' countries at all four international airports in Tamil Nadu would be ramped up from two per cent to 10 per cent from tomorrow, following an increase in the number of people detected with the 'S gene' drop, a possible indicator of the Omicron variant, the state government said here on Saturday.
The minister for medical and family welfare Ma Subramaian said 12 people detected with the Omicron variant in the state have been discharged from hospitals in Chennai, Tiruchirapalli and other cities after recovery, taking the 'active' Omicron cases in Tamil Nadu to 22.
