3rd May 2021 – (Hong Kong) The Centre for Health Protection (CHP) of the Department of Health said today that it is following up on a positive imported case of COVID-19 with the preliminary test result involving N501Y mutant strain. As N501Y mutant strain is with high transmissibility, the CHP decided to carry out prudent measures on infection control and prevention to arrange compulsory quarantine for asymptomatic residents of all units on all floors of the building concerned, so as to stop the potential risk of spread of N501Y mutant strain.
The case involves a 28-year-old woman who is a housewife. She took passenger flight UK6395 operated by TATA SIA Airlines (Vistara) from Delhi, India to Hong Kong on 4th April and underwent quarantine at Regal Oriental Hotel from 4th to 25th April. Upon completion of quarantine on 25th April, she returned to her residence at Beauty Mansion, 69-71A Kimberley Road in Tsim Sha Tsui. She sought medical advice at Queen Elizabeth Hospital on 26th April, where her sample collected at the Accident and Emergency Department of the Hospital was tested with negative result on COVID-19. In accordance with the requirements of compulsory testing, she underwent the 26th day testing upon arrival in Hong Kong at a community testing centre on 30th April and the result was indeterminate. She was arranged to be admitted to hospital for further testing on 2nd May. The test result was preliminary positive and she was also tested positive for COVID-19 antibody. Given the possible transmissibility of the patient during her presence in the community from 25th April to 2nd May, for prudence’s sake, in accordance with the Prevention and Control of Disease Regulation (Cap. 599A), the CHP will transfer asymptomatic residents of all units on all floors of the building (involving about 40 units) to quarantine centres. Symptomatic residents will be sent to the hospital for treatment. They will undergo compulsory quarantine for 21 days.
Separately, the CHP is continuing its follow up on confirmed local cases of COVID-19 (Cases No. 11643, 11672 and 11773) with test result involving N501Y mutant strain. Following the further investigations conducted by the Contact Tracing Office, the CHP found that all of the three cases have been to Citygate Outlets in Tung Chung on 11th April. Cases 11643 and 11672 had patronised a restaurant, Curry Lounge, at Shop S, G/F, SeaView Crescent, Tung Chung on the same day. The Government will issue a compulsory testing notice (CTN) to any person (including visitors and staff) who had been present at the two premises on 11th April. The Government reminds relevant persons to receive COVID-19 nucleic acid testing according to the CTN.
The CHP said that in view of the threat posed by the mutant strain, it is imperative for people to get vaccinated. As the Government has launched the COVID-19 Vaccination Programme, the CHP appeals to members of the public to get vaccinated as early as possible to protect themselves and others.
