The Centre for Health Protection today said it is investigating six additional imported COVID-19 cases, four of which involve the L452R mutant strain.

While the viral load of one case is insufficient for a mutation test, the remaining case's mutation test result is pending, the centre added.

The patients, aged one to 48, arrived from high-risk places. Three of them flew in from Pakistan via the United Arab Emirates and tested positive at Penny’s Bay Quarantine Centre as close contacts of imported cases confirmed previously. The other three arrived from India, the UK and the Philippines.

Separately, the centre reminds specified people linked to Way Man Court in Happy Valley to get tested tomorrow in accordance with a compulsory testing notice.

Due to an outbreak of upper respiratory tract infection and/or influenza-like illness in four schools, relevant schools or their specified levels are covered in another compulsory testing notice. Those who have finished their COVID-19 jab course can be exempted.

The Government will deploy a mobile specimen collection truck in North District and Yuen Long District tomorrow to provide free service for citizens subject to mandatory testing. Furthermore, the service period of the mobile specimen collection trucks in Kwai Tsing District and Sha Tin District will be extended to December 15.

In addition, from next Monday, the mobile specimen collection station at Sha Tsui Road Playground in Tsuen Wan will be relocated to the open space next to Tennis Court No. 4 at Tsuen Wan Park.

A total of 43 cases were reported in Hong Kong in the past 14 days, all of which are imported.
