"The man who has been working in Dublin, Ireland, for the last five years, arrived in the city flying from Manchester via Abu Dhabi and New Delhi. He was admitted to a hospital on Tuesday morning," the official said. His genome sequencing report from the National Institute of Biomedical Genomics (NIBMG) at Kalyani is expected within 72 hours, he added.

"He had tested negative for Covid on December 16 at a lab at Dublin, a day before his flight, and then again upon arrival at Delhi airport. He reached Kolkata on December 18 evening and went straight to his home. "From Monday morning, however, he started running a high-grade fever (103 degrees Fahrenheit or above) along with body ache, malaise and headache, after which a test showed that he was Covid positive," the official said.

The patient has said he had been indoors since his arrival in Kolkata, as per the guideline for international travellers which says they have to remain in home isolation for eight days, and venture out only after testing negative through an RT-PCR test.
