SINGAPORE – A new test that can detect coronavirus infections even in recovered patients has been used to link Singapore’s biggest virus cluster at the Grace Assembly of God church and the cluster at The Life Church and Missions.
In what is likely a world first, contact tracers used serological tests – which are done on blood samples – to identify a married couple as the missing link between the clusters.
The couple – cases 83 and 91 – had attended a Chinese New Year gathering in Mei Hwan Drive on Jan 25.
The Health Ministry (MOH) on Tuesday (Feb 25) said it determined the primary case in the Grace Assembly of God cluster was case 66, a 28-year-old Singaporean who works at the church and lives in Mei Hwan Drive.
Case 66 reported the onset of symptoms on Jan 29 – the earliest in the cluster of 23 cases, and went to work at the church while symptomatic.
Investigations showed that he had attended the same Chinese New Year gathering on Jan 25 as cases 83 and 91.
