The flareup is linked to a patron of Ursus Fitness, a gym in the Sai Ying Pun neighborhood on Hong Kong Island popular with expatriates.

The cluster is another blow to a city that has endured four waves of the virus. Venues ranging from gyms to beauty parlors were only allowed to reopen on Feb 18, after being closed for over two months, while restrictions on restaurant operating hours were eased. Bars and beaches remain closed.

The Hong Kong government on Friday ordered all gym staff in the city to have a virus test by Sunday.
