A total of 405 people, including 189 Covid patients, have died of Covid-19 in Rajshahi division last month alone as the situation is worsening in many border districts.
Shamim said that some 71 people have been admitted to the corona unit of the hospital in 24 hours, while 44 people were discharged after recovery.
Bangladesh has enforced a seven-day countrywide stricter lockdown, with effect from July 1, amid a surge in Covid-19 cases.
In mid-April, restrictions on activities and movement were imposed across the country as cases and fatalities rose to their highest levels since the start of the pandemic.
