I'm back in NYC - there were more controls to leave Australia (as Australians have been banned from travelling other than in certain circumstances - for me, returning to my home in the USA) than the USA (actually, there were no border controls at all beyond the usual visa check).
Let me focus today on Australia, where debate continues as to whether to lock everything down, or give up at an early stage "because of the economy". The latter is a terrible misconception - it is hard to believe our economy will thrive if we allow several percent of the population to die. I would like anyone who advocates for this to explain how we will choose who is turned away from hospitals, and where we should put the bodies. In New York right now, they're being stored in freezer trucks, as the morgues are already full.
Turning back to rational arguments, look at the chart below. This shows case numbers from the first day with over 200 cases - Australia is at day, shown in black below. Note that our outbreak has tracked that seen in Belgium quite closely. If we continue to do so, case numbers will double in another five or six days. For our full update, click this link.
