Four of the newly confirmed cases are linked to a new cluster at Orange Valley Nursing Home in 6 Simei Street 3, where they are all residents.
Three pre-school staff members, all Singaporean, also tested positive for COVID-19.

Most of Singapore's COVID-19 cases are foreign workers living in dormitories.
Singapore has about 200,000 foreign workers housed in 43 purpose-built dormitories. Another 95,000 workers are housed in 1,200 factory-converted dormitories, while 20,000 live in construction temporary quarters and another 85,000 work permit and S Pass holders in the construction sector live in HDB flats and private apartments.
In the past month, several people who worked in migrant worker dormitories have contracted COVID-19.
One of the new community cases reported on May 20 is a 57-year-old Singaporean man who had gone to work at Kranji Lodge 1 after experiencing onset of symptoms on May 16. The man is identified as Case 28834.
MOH also reported on May 16 that two Singaporeans who worked at foreign worker dormitories had contracted COVID-19, along with two household contacts of one of the cases.
One of them is a 31-year-old dormitory inspector. The Singaporean man is identified as Case 26927. It was not stated where he worked.
The other, a 54-year-old man, worked at Cochrane Lodge II. He is identified as Case 27390. Two of his household contacts - a 53-year-old Singaporean woman (Case 27006) and a 25-year-old Singaporean woman (Case 27388) - also contracted COVID-19.

On Wednesday, MOH said that COVID-19 cases among work permit holders living outside dormitories would now be added to the daily count of community cases. These cases were previously listed under a separate category.
A large number of work permit holders were placed on mandatory stay-home notices, but the notices have since expired.
"Hence we have now updated the definition of 'cases in the community' to include all cases (including among work permit holders) who are detected outside of the dormitories," said the ministry.
