Four more international travellers test COVID-19 positive at Delhi airport: Officials

Three out of the 243 people on the Air France flight that landed at the airport around 12 midnight tested positive for Covid, an official said.

One more person traveling with 195 others on a flight from London was found to be infected with coronavirus, the official said.

Their samples have been sent to the National Centre for Disease Control for genome sequencing to ascertain if they have the new variant, Omicron, which has been classified as a 'variant of concern' by the World Health Organization.

A total of eight people from "at-risk" countries have tested positive for COVID-19 since stricter norms for international passengers came into effect on Tuesday at midnight. The eight Covid positive travelers and two other passengers who showed "Covid-like symptoms" have been admitted to the Lok Nayak Hospital, where a dedicated ward has been set up for isolating and treating such patients.

According to the Centre, the countries designated as ''at-risk'' are European countries, including the UK, and South Africa, Brazil, Botswana, China, Mauritius, New Zealand, Zimbabwe, Singapore, Hong Kong, and Israel.

Under the new norms, RT-PCR tests are mandatory for passengers arriving from the ''at-risk'' countries and they will be allowed to leave the airport only after the results come.

Also, five percent of the passengers arriving on flights from other countries will be subject to the test randomly.
