Omicron: Tamil Nadu urges Centre to issue fresh norms for testing international passengers

Chennai: Tamil Nadu on Saturday requested the Centre to issue further set of guidelines on testing international passengers arriving in the state after a person from a 'non-risk country' tested positive for the Omicron variant of Covid-19 recently, becoming the first such case reported in the state.

Director of Public Health and Preventive Medicine, Dr T S Selvavinayagam in his letter to the Ministry of Health and Family Welfare Secretary Rajesh Bhushan requested that international passengers arriving in Tamil Nadu should undergo mandatory post-arrival testing of Covid-19 as against the current practice of testing only those passengers who arrive from 'at risk' countries.

According to him, 28 passengers, who arrived from various overseas destinations till Friday in Tamil Nadu, were detected with 's' gene drop indicating infection of Omicron variant of coronavirus. Of them, only four were from 'high risk' countries while the remaining from 'non-risk countries'.

Selvavinayagam pointed out that as per the current guidelines issued by the Centre, only 11 countries along with the European countries including the United Kingdom were declared as 'high risk' and additional surveillance protocol followed for passengers from these countries were being adhered to, but no additional surveillance protocol was being followed for passengers arriving from 'not at risk countries'.

"All international passengers arriving in Tamil Nadu should undergo mandatory post-arrival testing for Covid-19. If found positive, they will be treated as per existing protocol. They should be allowed to leave the airport to take a transit flight only if they are found negative", he said in his letter, which was shared with the media on Saturday.

"Only two per cent of passengers from non-risk countries are being randomly tested with RT-PCR and permitted to leave even before the results are declared, thereby increasing chances of missing passengers from non-risk countries infected with Omicron variant of being detected and leading to rapid transmission in the community", he said.

Selvavinayagam said passengers who have tested 'negative' should be advised to undergo home quarantine for seven days and again should take up a re-test on the eighth day of arrival in Tamil Nadu.
