The Centre for Health Protection today said it is investigating 27,467 additional COVID-19 cases, of which 15,789 were detected by way of nucleic acid tests and 11,858 were identified via rapid antigen tests.

For those who tested positive via nucleic acid tests, one case is imported and the rest are locally infected.

The centre reminded the public that those who register their positive test results through the declaration system for people who tested positive using rapid antigen tests (RAT) will have to complete their submissions within a day.

From March 14, a link sent through SMS to people with positive RAT results will only be valid for 24 hours.

People will need to upload their supporting documents with the link to complete their registration. Those who miss the deadline will not be able to get their isolation or quarantine order issued by the centre.

Now that the declaration system has been launched, the Government announced that the dedicated hotline 2280 4772 for those who reside or or work in areas with positive sewage signal, will cease operation starting at noon tomorrow.

Should people encounter any difficulties using the online platform, they may call the automated system at 1836 119 to register their identification document and telephone number. The centre will contact them to finish the report procedure.

Separately, the Government made restriction-testing declarations to cover designated buildings where sewage samples tested positive for the virus.

The buildings include Oi Yee and Oi Lok houses of Yau Oi Estate and Block 1 of Tsui Ning Garden in Tuen Mun, Wai Tung House of Tung Tau (II) Estate in Wong Tai Sin, Nga Yuen House of Chuk Yuen South Estate in Wong Tai Sin, Shun Man House of Oi Man Estate in Ho Man Tin and Yin Tat House of On Tat Estate in Kwun Tong.

People in the restricted areas must undergo compulsory testing before the specified deadline.

As there were positive sewage test results discovered in several housing estates in Southern, Tuen Mun, Kwai Tsing and Eastern districts, the district offices will distribute COVID-19 RAT kits to relevant residents as well as cleaning workers and property management staff working in such areas.

Starting tomorrow, the Government will reopen the mobile specimen collection station at the Kwai Chung Sports Ground Hard-surfaced Soccer Pitch.
