Switched off: phones of some international fliers

Around 11,000 international passengers have arrived in the city between March 9 and March 26, and tracking a number of them has turned out to be impossible, sources in the state government said on Tuesday.

The state health department and various municipal corporations and municipalities have remained in touch with a majority of them over the phone, seeking details about their health and trying to find out whether they have developed any symptom of Covid-19. But many others have remained unreachable.

An official of the Calcutta Municipal Corporation said: “There are some non-Indian passengers who we could not contact because their phone numbers provided by the airlines are switched off.
