Singapore recorded 528 new coronavirus cases as of noon local time today, according to the country's Ministry of Health.
That brings the total to 15,641 cases in the Southeast Asian city-state, according to Johns Hopkins University.
Among today's new cases, the vast majority are work permit holders residing in foreign worker dormitories, while six are Singaporean citizens or permanent residents.
The country's cases spiked dramatically at the start of April, and authorities traced the increase to clusters of cases in the dormitories. About 200,000 migrant workers live in 43 dormitories, where cramped conditions and shared facilities make it easy for a highly infectious virus to spread.
The dormitories are now all under lockdown, with nobody in or out. Authorities have taken residents showing symptoms to quarantine, stepped up testing, and are monitoring residents still inside the dorms.
