SINGAPORE – More than 12,000 people currently on stay-home notice (SHN) have begun an additional week of self-isolation, the immediate impact of stricter border restrictions, as Singapore tightens up its measures amid a flare-up of Covid-19 cases at home and in the region.

In a sign that there is no room for complacency, some 13,000 front-line workers at the airport and seaport are being tested for Covid-19 after four seaport workers and eight airport workers were found to be infected in the past 10 days.

While the majority of front-line workers here have been vaccinated, a new cluster of eight cases involving officers deployed at Changi Airport Terminal 3 was confirmed on Sunday night (May 9).
