With the new cases, the state now has 9 cases of the new variant.
The NRI (non-resident Indian) tested positive for the coronavirus infection in the RT-PCR test carried out at the Ahmedabad international airport soon after his arrival from the UK on December 15, a health department official said.
"The man's sample was later found infected with the Omicron variant," Anand district health officer Dr M T Chhari said as reported by The Indian Express.
He was scheduled to reach the Anand city in Gujarat from Ahmedabad.
"But, after he tested positive for the coronavirus, he was taken to the Ahmedabad civil hospital from the airport. The patient is currently recovering at the Ahmedabad civil hospital," Dr Chhari said.
His co-passengers and other contacts have tested negative for the viral infection, the official said.
On Saturday, a 15-year-old boy from Gandhinagar was also detected with the Omicron variant after returning from the UK, Gandhinagar Municipal Commissioner Dhaval Patel said.
