Hong Kong’s first community infection of a mutant Covid-19 strain involved the South African variant, officials revealed on Tuesday, with transmission likely to have taken place at a quarantine hotel via door hooks used by staff to deliver meal boxes to guests.
Experts found no problems with the hotel’s ventilation and drainage systems, the focus turned to S-shaped door hooks used by employees to hang meal boxes for self-isolating guests, who would later put them back there. ‘The virus could have been exchanged through contact with the hooks, which were “hard to clean”.’
