SINGAPORE - A fifth cluster of the coronavirus infection in Singapore was announced by the Health Ministry on Wednesday (Feb 12), after two infected people were found to have visited the Grace Assembly of God church.

Known as case 48 and case 49, the duo are Singaporean men with no recent travel history to China.

Case 48, who is 34 years old, lives in Bukit Batok Street 25 and visited Malaysia on Jan 26. He reported he had symptoms on Feb 1, and went to four different general practitioner clinics on five days: Feb 2, 4, 7, 9 and 10.

On Monday, he was admitted to the National Centre for Infectious Diseases (NCID) and was confirmed to have the virus, also known as Sars-CoV-2, on Tuesday afternoon.

Before his admission, he visited Plaza Singapura, The Star Vista and Fusionopolis.

He also went to work at Grace Assembly of God's Tanglin and Bukit Batok premises.

Case 49, who is 46 years old, reported the onset of symptoms on Feb 3 and visited a GP on Feb 8. He was taken to the National University Hospital's (NUH) emergency department the same day, but was discharged later that day.

He was back at NUH on Monday, and confirmed to be infected on Tuesday.

He is now warded at NUH.

Before his hospitalisation at NUH, case 49, who lives in Toh Guan Road, had gone to work at Grace Assembly of God's Tanglin and Bukit Batok premises.

Both cases were announced just one day after it was disclosed that a 39-year-old Bangladeshi worker, who had worked at the same Seletar worksite as another infected Bangladeshi national, had the virus.

The Life Church and Missions in Paya Lebar was identified as a cluster last Saturday evening, with five cases - 8, 9, 31, 33 and 38 - linked to it.

The church said that cases 8 and 9 were foreigners who had visited the church on their own.
