Australia is being hit by a fairly sizable second wave of Covid-19, while New Zealand has no significant community transmission. (Just a few imported cases in quarantine.) As of today, New Zealand has only 22 active cases. Australia has 9238.
Those are the facts, but facts can be misleading. Outside of the two states of Victoria and New South Wales, Australia has only 22 active cases, exactly the same number as New Zealand. And while the other Australian states are not particularly populous, their combined population is close to 12 million, vs. 5 million in New Zealand.
(Taiwan has 30 active cases in a population of 24 million. It is also free of community transmission.)
So while Australia is having a second wave, so far it’s mostly in Melbourne. (Knock on wood.) It will be interesting to see if they can keep it contained.
