【明報專訊】Just when things are looking grim for Hong Kong's fight against the COVID-19 pandemic, it has been revealed that 10 senior officials attended a large-scale birthday party on Monday (3 January). The Centre for Health Protection (CHP) discovered afterwards that an attendee has tested preliminary positive. Secretary for Home Affairs Caspar Tsui, who also attended the party, has been listed as a close contact and is to be isolated at the Penny's Bay Quarantine Centre. With Omicron bearing down on the city, the Secretary for Food and Health had urged the public to avoid going to crowded places or participating in large events. Senior-ranking officials should have led by example and exercised strict self-discipline.
