What is going on with COVID-19 in Australia? I looked at the graph of cases. At first it looks like normal exponential growth
but when you look at the log plot, it’s still growing faster than linear
This could imply that Australia’s testing is getting exponentially better (or even just polynomially better) as the virus spreads exponentially among the population but polynomially improving testing for several weeks would be quite a feat.
It seems more likely that there’s a second source of growth (like a bunch of tourists bringing the virus in). That would also account for the dramatic rise in cases that aren’t yet at the stage where they are causing death, which remains oddly low & seemingly linear.
Any data analysts or virologists have a better grip on what’s going on here than my armchair analysis?
