SINGAPORE: Ten community cases were among 28 new COVID-19 infections reported in Singapore as of noon on Sunday (May 9), said the Ministry of Health (MOH).

Seven of the 10 community cases are linked to previous cases, said MOH on Sunday night, after it said on Sunday afternoon in its preliminary daily update that five were linked.

Three community cases are unlinked.

The remaining 18 cases were imported and were placed on stay-home notice or isolated upon their arrival in Singapore, MOH said.

No new infections were reported in migrant workers' dormitories.


Three of the seven linked community cases had been patients at Tan Tock Seng Hospital (TTSH) Ward 9D. All of the new cases linked to the TTSH cluster are Singaporeans.

The cluster, which had no new cases for four consecutive days, now has 43 infections in total.

He was confirmed to be positive the next day and he was taken by ambulance to Alexandra Hospital, MOH said.

The man's serological test result is negative and he has not worked since the onset of symptoms.

He tested preliminarily positive for the B1617 variant of the virus that was first discovered in India, and is pending further confirmatory tests.
