The Herald newspaper in a report Sunday said the President has been flown to London for treatment after coming into contact with a COVID-19 patient.
Reacting to the report, Mr Arhin said the President is in self-isolation at the Presidential Villa at Jubilee House. He said the President will be in isolation for 14 days.
Former President John Kufuor and wife former first lady Theresa Kufuor have been isolated over COVID-19 fears.
The former first couple has been taken out of their residence after some security officers in their house allegedly tested positive for the virus, Starr News has gathered.
It is unclear where they are isolating.
