A sub-inspector (SI) of Bhairab police station in Kishoreganj tested positive for coronavirus infection on Friday.
Dr Md Mujibur Rahman, civil surgeon of the district, confirmed the matter, reports UNB.
Following the detection of the infection, 15 colleagues of the SI and five doctors were sent on institutional quarantine.
Besides, the local administration has cut the communications of the upazila with other parts of the country to prevent the transmission of coronavirus.
A public notice was issued on Friday in this regard.
As per the notice, no one will be allowed to enter or leave the upazila until further notice.
Besides, the upazila administration identified the places where the police official moved in the last few days and marked those by hoisting red flags.
The places include the police officer's mess, the alley where the mess is situated, female and male wards of Bhairab Upazila Health Complex, office of its resident medical officer, a private hospital, and Kalikaprasad and Shibpur unions.
It was learned that the police official went to the private hospital first after he fell ill. As his condition did not improve, he approached the upazila health complex where doctors suggested testing for coronavirus.
Civil Surgeon Mujibur Rahman said people who came in contact with the SI will be brought under surveillance and their samples will also be collected for tests, if necessary.
A total of 22 samples were sent to the Institute of Epidemiology, Disease Control and Research (IEDCR) in Dhaka from Bhairab, he said.
They received the results of 17 samples where only the police officer was found to be positive, the civil surgeon said, adding that he was sent to Kurmitola General Hospital in Dhaka.
