Singapore confirmed 788 new cases of coronavirus today, raising the country’s total past 20,000 infections.

The vast majority of these new cases are foreign migrant workers living in dormitories, where clusters have made the country’s numbers spike dramatically in recent weeks.

The country has now recorded 20,198 cases and 18 deaths, according to data from Johns Hopkins University — the highest caseload in Southeast Asia.

Singapore reopens: The city-state started a phased return to work yesterday. Businesses that reopen will be required to follow strict new rules, including the wearing of face masks all day in the office and no gathering among staff during lunch breaks.

The Ministry of Health calls the new measures the “new normal in a Covid-19 world.”

Starting from May 19, schools will also reopen, for those who have practical sessions and need additional support.

But for migrant workers isolated inside dormitories, restrictions on daily movements will stay in place until June 1.
