The number of confirmed cases linked to Ursus Fitness in Sai Ying Pun rose 13 on Monday to a total of 122, making it the cityâs second-biggest cluster after one in November that was centered on dance halls. The Health Department said at a press conference that 860 close contacts of those infected have been sent to quarantine. Separately, the government said it would expand eligibility criteria so that more people could get vaccinated.
