What exactly is the plan for HK (and everybody else in Asia for that matter?) Just hunker down until it disappears?
Clearly, we can't keep doing this forever. Whilst a vaccine looks odds on to be found by someone, it'll take a long, long time to roll it out globally.
Surely there has to be some joined up thinking and dare I say it, some pragmatism like we're seeing in Europe (although it certainly isn't universal). There is limited evidence that quarantining people, or banning people altogether, has an effect on infections when the virus is already ingrained in the population.
