The Centre for Health Protection today said it is investigating 24 additional COVID-19 cases, of which 18 are locally transmitted.

At a press briefing this afternoon, the centre's Communicable Disease Branch Head Dr Chuang Shuk-kwan said that among the local cases, nine have unknown sources of infection.

She said residents of the seven buildings where the patients live have to undergo compulsory virus testing.

Additionally, three buildings in Tung Chung, Pok Fu Lam and Kowloon City have been included in the compulsory testing notice.

The Government will set up mobile specimen collection stations at Shek Ku Lung Road Playground in Wong Tai Sin and Kwong Fuk Estate in Tai Po on February 13, while the service period of the mobile stations at Kwun Chung Sports Centre in Jordan and MacPherson Playground in Mong Kok will be extended to February 16.

People subject to compulsory testing can choose to go to mobile specimen collection stations or any of the community testing centres in all districts to receive testing free of charge.

Among the six imported cases, two arrived from Indonesia, two from the United Arab Emirates, while the remaining two came from the Philippines and India.
