The new Omicron variant of the coronavirus could be more contagious than the prevalent Delta strain, judging by a “surprisingly distant” transmission in a Hong Kong hotel, a top microbiologist warned on Wednesday, as a transit passenger who spent days at the airport became the city’s fourth case.
Medical experts from the University of Hong Kong also urged the public not to wait for a next-generation Covid-19 vaccine against the heavily mutated variant, saying existing shots were still useful.
The HKU team, which on Tuesday night revealed it had successfully isolated the new variant, said it would partner with companies in mainland China to develop a vaccine targeting Omicron.
