This came as Hong Kong logged five additional infections today, including two local cases, aged 66 and six respectively, that were detected at Block 3 of Oi Fai House in Yau Oi Estate.

The Centre for Health Protection is also looking into two preliminary-positive cases who are family members residing in a unit 32 of the block.

Among the four confirmed cases involving the building, three of which are residents of unit 09 on the 21st and 23rd floor while the other lives in unit 31 on the 22nd floor.

On Friday, residents of unit 09 on all floors were sent into quarantine following a site visit made by government adviser Professor Yuen Kwok-yung, who suspected the virus transmitted through pipes of the building.

Given that units 09 and 10, and units 31 and 32 separately share a common soil pipe, the CHP said today it would further issue quarantine orders to all residents of units 10, 31 and 32 on all floors of the residential building.

The remaining three new cases detected today are imported cases from the Philippines, Pakistan and India.

A total of 124 cases have been recorded in the past 14 days (March 27 to April 9), including 23 local cases of which 10 are from unknown sources.

The city’s official tally stood at 11,564 which included 206 related deaths.
