All the Omicron infected people were asymptomatic and their conditionĀ was stable. They were undergoing treatment in government and privateĀ hospitals.
Subramanian said of the total 57 samples sent for testing, 33 returned positive and the results of the balance 24 samples were awaited.
He also said that 20 more air passengers have reported S-gene drop out, seen as a marker to Omicron and their samples were sent to Bengaluru lab for testing. They were quarantined and were under observation.
Health Secretary Dr J Radhakrishnan said all those infected with Omicron are being provided treatment with four-tier security.
In view of the increase in the number of Omicron cases, the health department officials have intensified surveillance in all the airports in the State to prevent the virus spread.
The State government had already written to the Centre seeking permission to test all passengers arriving from low-risk countries as the number of Covid cases from these countries were higher than those carriving from high-risk countries.
It said random testing of two per cent of passengers from low-risk countries would not yield the desired results in preventing the spread of the Omicron variant.
