Continuing with my New Zealand theme, here is Jacinda Adern letting the children of New Zealand know that the Easter Bunny is definitely an Essential worker. The first time I saw this concept was the Premier of Western Australia (who put out a press release), but as usual Jacinda AdernContinue Reading
Insight Today I’m looking at New Zealand. First, this Washington Post article admiringly describes what has been happening there – New Zealand isn’t just flattening the curve it’s squashing it (this article may be paywalled, it wasn’t the first time I saw it but it seems to be now) andContinue Reading
The Australian government has released modelling about the Covid19 pandemic and its possible impact on the health system (for some reason they have been quite reluctant to do so). I haven’t had a chance to read it yet, so I’ll be blogging about it tomorrow. But if anyone would likeContinue Reading
Today’s Insight Today, I’m looking at the testing data – how much is positive. The graph belows the trend of what proportion of Covid19 tests in Australia is positive. The graph shows that the percentage of positive tests is slowly increasing. When this data was first reported, NSW only hadContinue Reading
Today’s link I’ve talked a lot about levels of testing on this blog. Australia continues to test for Covid19 at a higher level than many countries around the world. And the proportion of tests that are positive continues to hover around the 2% level in Australia, which is a reassuringlyContinue Reading

The Imperial researchersContinue Reading
Today’s insight As we’ve watched around the world, the most dramatic indication of the impact of Covid19 has been the stories coming out of intensive care units – health professionals in Wuhan, Lombardy, Madrid and now New York are making heartbreaking decisions because there just aren’t enough ICU beds forContinue Reading
Today’s Insight This great post on linkedin talks about the difficulty of calculating a case fatality rate for Covid19. A case fatality rate is the probability that someone will die if they are infected with Covid19. And to calculate the rate you need a numerator – a number of deaths,Continue Reading
Today’s Insight Today’s insight is just a brief one, it is about exponential growth. We spend a lot of time talking about how the growth of Covid19 is exponential. But exponential growth is not intuitive. To illustrate this to myself, I built a very simple model. I looked at theContinue Reading
Today’s insight I’ve previously written that the number of positive tests in any country is not necessarily a good measure of how prevalent Covid19 is in that country. It really depends on how much of the population is being tested, and how many of those tests are positive. I hadContinue Reading
