But a few weeks later, Omicron came to the metropolis again, this time causing an outbreak among cleaners at a public-housing estate that spiralled out of control. The conflagration of resulting cases is now killing people at a rate exceeding that of almost any country since the coronavirus emerged.
But it was relevant again in the United States, too, where subpar vaccination and booster rates among older people have left scientists concerned about a potential surge of BA.2 cases. Partly because so many more Americans have been infected and killed by the coronavirus during earlier waves, scientists do not expect the United States to face as serious a situation in the coming months as Hong Kong.
Less than one-quarter of people aged 80 and over in Hong Kong had been given two doses of a vaccine before Omicron surged, compared with more than 90 per cent of people in Singapore and New Zealand. The city has now vaccinated 39 per cent of residents aged 80 and above, despite having inoculated almost two-thirds of 12- to 19-year-olds.
Unlike other parts of Asia that had gradually lifted restrictions in recent months, Hong Kong was not ready for its defenses to fail, scientists said. Dr Cowling, of the University of Hong Kong, said that his city could have responded in one of two ways to signs that cases would surge: Either double down on “zero Covid” through measures like building better quarantine facilities for overseas arrivals, or acknowledge that outbreaks are unavoidable and raise vaccination rates.
