The Centre for Health Protection today said it is investigating two additional COVID-19 cases involving men who arrived from Tanzania and the US.

Meanwhile, the centre was notified yesterday of a confirmed case in the UK concerning a 46-year-old man who left Hong Kong for London on Cathay Pacific flight CX251 on July 15. His specimen collected on July 17 tested positive for COVID-19. He was asymptomatic. The centre is following up on the case with the British health authority and epidemiological investigations are underway.

As a prudent measure, Rosedale Hotel Hong Kong, Causeway Bay where the patient had stayed during the incubation period was put under a compulsory testing notice last night, requiring people who had been at the venue for more than two hours from July 4 to 28 to get tested on or before July 31.

In addition, as two non-locally confirmed cases had lived in Hong Kong, three specified premises are included in the latest compulsory testing notice.

For a previous imported case with the L452R mutant strain, those who had been at two specified premises during the specified period have to undergo additional testing.

A mobile specimen collection station will be set up at Taikoo Park outside One Island East tomorrow, while the service period of the mobile station at the Quarry Bay Community Hall carpark will be extended to August 1.

A total of 25 cases were reported in Hong Kong in the past 14 days and all of them were imported.
