The Centre for Health Protection today said it is investigating two additional imported COVID-19 cases, both involving mutant strains.

The cases involve a 51-year-old man and a three-year-old girl. The man arrived in Hong Kong from the UK, while the girl had travelled from Mongolia and Korea.

Both of them tested positive upon arrival at Hong Kong International Airport.

Meanwhile, specified people linked to Tower 10, Phase 3 - The Graces, Providence Bay in Tai Po are reminded to undergo testing tomorrow in accordance with the compulsory testing notice.

Two schools or their specified levels are covered in the latest compulsory testing notice due to an outbreak of upper respiratory tract infection or influenza-like illness.

The Food & Health Bureau announced that the testing frequency for airport staff of targeted groups will be enhanced to one test every three days starting tomorrow, as an enhanced precaution for the fifth wave of the epidemic.

The daily booking quota of the airport's community testing centre at the Ground Transportation Lounge will be increased to over 3,000 starting tomorrow. The testing centre will also be supplemented with additional manpower.

The Government will also temporarily increase the number of booths at the mobile specimen collection station at South Transition Deck, L6, Terminal 1 tomorrow to divert airport staff who need to undergo testing.

It will adjust the service arrangements depending on the testing centre’s actual usage.

A total of 69 cases were reported in Hong Kong in the past 14 days, one of which is a local case with an unknown infection source and the rest are imported.
