The vast majority of these cases are work permit holders residing in foreign worker dormitories, MOH said.
Ten are Singaporeans or permanent residents.
“The number of cases amongst migrant workers has been fluctuating in recent days due to clearance of backlogged cases by one laboratory,” said MOH. 
The ministry said it is working with the laboratory to stabilise its operations.
The breakdown is as follows:
a) Imported cases: 0
b) Cases in the community: 13 (10 Singaporeans/Permanent Residents, 3 Work Passes)
c) Work Permit holders (residing outside dormitories): 18
d) Work Permit holders (residing in dormitories): 626
Of the new cases, 87% are linked to known clusters, while the rest are pending contact tracing.
61 more cases of COVID-19 infection have been discharged from hospitals or community isolation facilities. In all, 1,408 have fully recovered from the infection and have been discharged from hospitals or community isolation facilities.
There are currently 1,630 confirmed cases who are still in hospital. Of these, most are stable or improving, and 22 are in critical condition in the intensive care unit.
This is the tenth day in a row where new daily infections fell below 1,000, with local cases excluding those in dormitories remaining low.
