The Centre for Health Protection today said it is following up on the patient of a positive COVID-19 case, with the preliminary test result involving the N501Y mutant strain, who lives in Tung Chung.

The case involves a 39-year-old female domestic helper. A 10-month-old girl who lives with her is also a positive case. They reside at Tower 11, Carmel Cove, Caribbean Coast, 1 Kin Tung Road in Tung Chung.

As the N501Y mutant strain has high transmissibility, the centre will carry out prudent measures on infection control and prevention to arrange compulsory quarantine for asymptomatic residents of all units of the building concerned. Symptomatic residents will be sent to the hospital for treatment.

They will undergo compulsory quarantine for 21 days.

As the case involving the mutant strain had visited St Thomas the Apostle Church at 5 Tsing Luk Street in Tsing Yi on April 11 and 18, a compulsory testing notice has been issued to require people who stayed there on those days to undergo testing by May 1.

The centre has also arranged compulsory quarantine for close contacts who had attended a church gathering with the woman and has informed household members of close contacts to undergo compulsory testing.

Four other places where the patient had visited are also included in the compulsory testing notice. People who had been present at those places during the specified period must undergo testing by May 1.

The Government will set up a mobile specimen collection station at Fu Tung Estate in Tung Chung on April 30 for people subject to compulsory testing, while the operating hours of the station at Tung Chung North Park will be adjusted.

The centre urged those who have been tested to avoid going out until their results are ascertained.

As the patients of today’s case and an earlier one involving the mutant strain are domestic helpers, the centre advised employers to remind their helpers to avoid gatherings, food sharing and other social activities.

If they have to attend gatherings, they should wear a mask at all times, wash their hands frequently and maintain social distancing.

Employers should also pay attention to their domestic helpers’ health and seek medical attention immediately if symptoms develop.
