The Centre for Health Protection today said it is looking into 4,180 additional locally acquired COVID-19 cases, of which 1,289 were directly identified through nucleic acid tests and 2,891 via verified rapid antigen tests.

Separately, 196 imported cases were reported and three more patients passed away.

The centre added that five residential care homes for the elderly and one for disabled people identified infection cases.

There were also 287 virus cases reported by 231 schools. Three schools were advised to suspend face-to-face lessons for specific classes for one week.

Due to a number of positive cases, 55 specified places are included in a compulsory testing notice. It also covers five specified premises in Tai Po where some sewage samples tested positive for the virus.

The Government will reopen the mobile specimen collection stations at Hing Wah (II) Estate in Chai Wan, Shek Pai Wan Estate in Southern District, Wang Tau Hom Estate in Lok Fu and Cheung Ching Estate in Tsing Yi tomorrow. The service period of the collection stations at Wah Kwai Estate in Southern District and On Yam Estate in Kwai Chung will be extended to August 13.

Meanwhile, the Government made a restriction-testing declaration to cover Ka Sin House of Ka Keng Court in Sha Tin, 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 areas in Sha Tin, Southern and Yau Tsim Mong districts, the respective district offices will distribute COVID-19 rapid test kits to relevant residents as well as cleaning workers and property management staff working there.
