Standing in a taxi queue recently I overheard a middle-aged man say to a woman of similar age ahead of him in line, “I got 650”. Whatever he was referring to, he was clearly pleased with his result and he asked what she got. She smiled and said, “8,500”. His face fell and it took a little more eavesdropping – it’s to be expected if you speak loudly in a cab queue – to realise they were discussing their Covid-19 antibody test results.

A domestic worker who recently arrived in Hong Kong from the Philippines has been confirmed as carrying a mutation of the coronavirus, making her the third local case involving the more infectious strain.
The woman had completed quarantine at a hotel in Sai Ying Pun where two people staying in an adjacent room were confirmed as carrying the N501Y mutation, raising fears the virus had spread on the floor, health authorities said on Friday.
