There were 100 deaths in the past week and, with some 8,364 people testing positive on June 28, the highest since the pandemic hit the country last year, the government has decided to shut all public and private offices for at least a week.
Cabinet secretary Khandker Anwarul Islam said the army and law enforcement agencies would be patrolling to enforce the lockdown.
Activities at the country's seaports, however, will remain open, and although the country's main foreign currency earners, the garment factories can also stay open, following strict health safety rules, there are concerns, reports London's The Loadstar.
'Shutting garment factories, even for a day, will be disastrous,' warned Siddiqur Rahman, former president of the Bangladesh Garment Manufacturers and Exporters Association (BGMEA).
He said, with the Eid ul Azha festival in a few weeks: 'We have to pay festival bonus and wages before that. If we can't produce and make shipments we will incur huge losses.'
Meanwhile, despite a pandemic-induced slowdown across the country, Bangladesh's main port of Chittagong handled over 3 million TEU in the fiscal year.
In year 2019-20, the port handled 2.79 million TEU, slightly below the 2.8 million TEU in 2018-19, which is largely blamed on the initial impact of the first wave of the pandemic.
'Both exports and imports gained pace during the past couple of months as the pandemic eased in western countries,' said a Chittagong port official, explaining this year's increase in volumes.
However, long berthing delays at Chittagong and outlying transshipment ports have reduced the available capacity of feeder vessels, which along with non-availability of some feeder ships, has created a stockpile of export containers at the inland container depots responsible for the stuffing of boxes for export.
Ruhul Amin Sikder (Biplob), secretary of the Bangladesh Inland Container Depots Association (BICDA) said the number of export boxes at the depots was double the normal level, a situation that has persisted over the last month or so.
'Some containers are lying at depots for up to 15 days,' he said.
As of last Friday, there were some 10 containerships waiting at the outer anchorage of Chittagong port, with nine at jetties loading and unloading containers.
