NZ prime example 102 days without a case then a flare up over something as simple as an imported pork chop (or similar) Point is if the virus got there that easily that’s a wrap on travel in OZ.
Interesting to consider what happens if there is never (or even not within 5-10 years) a vaccine or suitable treatment. Given the rest of the world has not opted for elimination strategies, what is our long term plan then?
Clearly as NZ has shown, all international freight will need to stop as well. So how long does the country function in complete isolation? Just like influenza, Covid will always be somewhere on the planet.
One way or another, whether by vaccine, treatment or sheer risk/reward mentality, this will have to end. When is anyone's guess.
