BANGKOK >> Singapore has reported its biggest daily jump in new coronavirus infections, most of them linked to foreign workers living in crowded dormitories.

Foreigners account for over a third of Singapore’s workforce, many of them people from poorer Asian countries working in construction, shipping and maintenance jobs that support Singapore’s trade-reliant economy.

Over 200,000 Asian migrant workers live in 43 registered dormitories that house up to 20 men per room, with shared toilets, cooking and other facilities.

The 386 newly confirmed cases raise Singapore’s tally to 2,918. Health authorities also reported a ninth death in a statement late Monday.

The tiny city state of nearly 6 million people has shut down nonessential businesses and schools until May 4 in a partial lockdown to try to halt the spread of the new coronavirus. Tens of thousands of foreign workers are quarantined in their dorms and some were moved elsewhere to reduce crowding.

Environment and Water Resources Minister Masagos Zulkifli wrote on Facebook late Monday that the remaining three weeks of the partial lockdown will be “a critical window that will determine if we can successfully flatten the curve, prevent large-scale community spread, and save our loved ones.”
