SINGAPORE - Singapore reported 233 new coronavirus cases on Sunday (April 12) and seven new clusters, said the Ministry of Health (MOH) in its daily update.

While the number of cases in the community has increased following a wave of imported cases, there has been some moderation in recent days, in the light of the safe distancing measures that have been put in place, the ministry added.

The number of imported cases rose in the middle of last month due to the large number of returnees, but has since come down to zero, it said.

Among the new cases, 51 are linked to known clusters, 15 are linked to other cases, and 167 are pending contact tracing. None are imported cases.

Of the 167 pending contact tracing, 141 are work permit holders who are mostly residing in dormitories, work sites, and other living quarters, said MOH.

This brings the total number of cases to 2,532.

The new clusters are: Acacia Lodge, Tuas View Dormitory, 36 Woodlands Industrial Park E1, Kallang Dormitory, the Black Tap burger joint at Marina Bay Sands, a construction site at 9 Penang Road, and the McDonald's outlets at Forum Galleria, Lido and Parklane.

Five employees of McDonald's who worked at the Lido, Forum Galleria, Parklane as well as Geylang East Central outlets were diagnosed with Covid-19, said the fast-food chain earlier on Sunday.

They have since been quarantined in medical facilities, and all other employees who worked at the affected branches have been told to isolate themselves with a 14-day leave of absence.

The four restaurants have been cleaned and are closed for business until further notice.

Clusters at foreign worker dormitories continued to grow. For instance, 30 more cases were linked to S11 Dormitory @ Punggol, which now has 365 cases.

In a Government Gazette notice on Sunday, the Cochrane Lodge II dormitory was declared an isolation area. This will take effect on Monday.

It became the eighth foreign worker dormitory to be gazetted as such, along with others like Cochrane Lodge I, Acacia Lodge, and Tampines Dormitory.

In a Facebook post after midnight, Minister for National Development Lawrence Wong noted that the number of work permit and dormitory-related cases has increased sharply recently.

"This is likely to continue going up, especially as we undertake more aggressive testing of workers at the dormitories," he wrote, adding that there is a "comprehensive strategy" to take care of foreign workers and contain the virus in dormitories.

He said that while the "circuit breaker" measures are in place to slow down the spread of the virus in our community, its full effects will only be seen in the next one to two weeks.

"So let's press on with our efforts to stay home, minimise contact with others, and break the transmission chain in our community," he added.

Of the 976 confirmed cases who are still in hospital, most are stable or improving, and 31 are in critical condition in the intensive care unit.

Another 32 patients have also been discharged from hospitals or community isolation facilities, bringing the total who have fully recovered to 560.
