SINGAPORE - A mass testing exercise for visitors of Block 506 Hougang Avenue 8 and residents and visitors of nearby blocks of Housing Board flats is complete with 4,384 people testing negative for the virus.

There were no positive tests, said the Ministry of Health (MOH) in a reply to media queries on Friday (June 11).

Her infection was linked to 12 others.
