SINGAPORE: Singapore reported 486 new cases of COVID-19 as of noon Monday (May 11), bringing the national total to 23,822.
The vast majority of cases are work permit holders residing in residences for foreign workers, the Ministry of Health (MS) said in its daily preliminary update.

Two cases are Singaporean or permanent residents.
“The lower number of cases today is in part because fewer tests are being processed in a test lab, and you are recalibrating your device for one of the test kits,” said the Health Ministry.
More details of the new cases and more updates will be shared later in the day, the ministry added.
