The Centre for Health Protection today said it is investigating 1,680 additional locally acquired COVID-19 cases, of which 620 were directly identified through nucleic acid tests and 1,060 via rapid antigen tests which were verified.

Separately, 114 imported cases were reported.

The centre also received notifications of three positive cases from the same school – Yuen Long Public Middle School Alumni Association Tang Ying Yip Primary School. They all study in class 6D and 20 pupils in the class had to suspend themselves from in-person classes for a week.

The cluster from a restaurant at Chelsea Heights in Tuen Mun registered three more infections, bringing the number of COVID-19 cases there to 40.

Due to a number of positive cases, 24 specified places are included in a compulsory testing notice. It also includes two buildings in Chai Wan and Cheung Sha Wan where some sewage samples tested positive for the virus.

People subject to compulsory testing may visit the mobile specimen collection stations or community testing centres to undergo testing.

Meanwhile, the Government made a restriction-testing declaration to cover King Fai House, Yue Fai Court in Aberdeen, requiring people in the restricted area to undergo compulsory testing before the specified deadline.

As there were positive sewage test results with relatively high viral loads in several housing estates in Tuen Mun, Kowloon City, Yau Tsim Mong and Wan Chai districts, the Housing Department and respective district offices will distribute COVID-19 rapid test kits to relevant residents as well as cleaning workers and property management staff working there.
