Hong Kong’s third wave of Covid-19 cases could peak in two weeks, with sweeping social-distancing measures bringing the ratio of the number of people infected by each carrier down by more than two-thirds over the past fortnight, according to a leading expert.

Professor Gabriel Leung, dean of the faculty of medicine at the University of Hong Kong (HKU), said the fall in the “effective reproductive number” for the coronavirus meant the rate of an infected person spreading the pathogen to more than three others had fallen to just under one.

[Residents’ efforts] are to be commended, but [they] must be continued, and we must persevere for at least a few more weeks

He also cited latest traffic data, which revealed that most age groups had reduced their mobility down to March levels when the health crisis last peaked, except students, some of whom might still be out and about during the summer holiday.

“[Residents’ efforts] are to be commended, but [they] must be continued, and we must persevere for at least a few more weeks to suppress the epidemic dynamics,” said Leung, who is also a government adviser. “I am hopeful that the number of daily reported cases can peak in two weeks.

“We need to watch these indicators on a daily basis, and the moment they start to have an uptick or stop falling, then it’s probably time to quickly reassess whether we need more draconian measures,” he added, when asked about whether a lockdown might be necessary to flatten the curve.
