The Bangladeshi national, hailing from Kanaighat upazila, returned on February 29.
He was admitted to Ragib Rabeya Medical College Hospital on Wednesday with fever and cold related problems, said Civil Surgeon Premananda Mandal.
Doctors later recommended shifting the patient to Kurmitola General Hospital in the capital suspecting Coronavirus but he stayed at his home.
Then, he went to Sylhet Osmani Medical College Hospital at night for treatment and the hospital authorities sent him to 14-day quarantine at Shaheed Shamsuddin Ahmed Hospital, Mandal said, adding that a medical board will examine him today.
An 11-member multisectoral committee was formed to prevent coronavirus following the hospitalization of the Dubai-returnee.

Meanwhile, a team of Institute of Epidemiology Disease Control And Research (IEDCR) collected sample from the Dubai-returnee’s body on Thursday afternoon, said Dr Nur-e-Alam Shamim, deputy civil surgeon.
