Insight Recent antibody testing in New York has added weight to my hypothesis that the infection fatality rate of Covid19 is around 1%. New York has done some random-ish population testing of antibodies to the Sars-Cov2. This New York Times article has the story. In New York City, about 21Continue Reading
Insight – Air pollution I have read a lot of people recently talking about how clear our skies are, given how few cars there are on the road. Sydney has had some beautiful days lately. So are we managing to reduce pollution (and hence improve our chances if Covid19 getsContinue Reading
