Hong Kong’s Covid-19 measures must be driven by scientific fact, not fear

The middle road between a strict zero-Covid-19 policy and a dangerous ‘let it rip’ scenario is grounded in science and promotes quality of life

It requires us to focus on sensible long-term measures such as wearing masks, getting vaccinated, gathering only outdoors, and improving indoor ventilation

More than two years into the Covid-19 pandemic, and with yet more measures being introduced by the Hong Kong government, it seems like we’re in a perpetual state of “déjà vu all over again” (as US baseballer Yogi Berra put it), and no closer to “normal”. It’s incredibly tiresome, yet as a Los Angeles Times article noted this month, while many might say they are “done with Covid”, Covid’s not done with us.

Perhaps, then, it is worth looking at how science suggests Covid-19 will pan out and ways we might respond. First, as I’ve written before, Covid-19 spreads efficiently well before symptoms even develop, so there is no real pressure for it to evolve towards being less dangerous, or simply “disappear”, as former US president Donald Trump predicted.

Second, Covid-19 is airborne, which means that, much as unprotected sex carries a risk of contracting HIV, unprotected breathing might result in Covid-19.

Worldwide, responses to Covid-19 vary, with few anywhere near as draconian as in Hong Kong. Even before the February 8 announcement of even more stringent measures, there were suggestions on social media that the government’s policy was unduly restrictive and severely compromising Hong Kong’s role as a “world city”.
