The two Singaporeans - a 74-year-old man and a 19-year-old woman - travelled from India and the United Kingdom respectively. Both were asymptomatic when tested.
The two long-term visit pass holders arrived from Russia and Indonesia, while the work permit holder, who is currently employed in Singapore, came from Indonesia. They were all asymptomatic when tested.
MOH said all close contacts of the imported cases have been isolated and they will be tested at the start and end of their quarantine period to detect asymptomatic cases.
The ministry added that the number of new cases in the community has remained low, with just one case in the past week, which is currently unlinked.
With four cases discharged yesterday, 58,018 patients have fully recovered from the disease.
A total of 40 patients remain in hospital, while 23 are in community facilities. None is in intensive care.
