Very quickly, I think the key to the responses of the countries that have proved best able to deal with COVID-19 quickly out of the gate—countries such as Australia, New Zealand, Taiwan, and Korea—was first of all that they had the capacity to take the threat seriously and understand the seriousness of the risk. That was a capacity that linked public health experts with government decision-making. I think culturally, to be honest, in all those countries, it was rooted in their experience of SARS, a memory that stuck.
There were a whole host of issues, but one of the key things they did, and probably a key measure at the outset, was early and very strict border closures.
