The local administration will lock down Narsingdi from Thursday morning to contain the spread of the deadly Covid-19 in the district.
District Deputy Commissioner Syeda Farhana Kawnine declared the lockdown on Wednesday afternoon.
"The lockdown will be effective from the morning of April 9, and continue until further notice," said Imrul Kayes, additional deputy commissioner (education and ICT).
He continued, "The two patients, diagnosed with coronavirus in Narsingdi, came from Narayanganj. We are restricting entry and exit from the district for the wellbeing of the people.
"Restrictions on movement will be imposed in all roads throughout the district except the Dhaka-Sylhet highway."
Emergency services, such as medical and food supply will be out of the purview of the restriction.
Meanwhile in Sunamganj, locals locked down the entry and exit routes of some of the villages after thousands of garment workers returned to a village.
Villagers claimed that most of the returnees did not maintain any sort of home quarantine and roamed around the village shortly after their arrival.
