The COVID-19 pandemic has brought to public attention, like never before, the work of public health physicians as well as epidemiologists, statisticians and computer modelers. The crisis also shown how hard it is to take decisions affecting the lives of millions when there is so little evidence to go on. Models of viral spread and interventions to mitigate these have become everyday discussion points, but few people understand how hard these are to put together. In this podcast we share expert talks that were presented at the RACP Congress in April and May. While they precede the latest developments of the delta strain and the National Plan to curb it by increasing vaccination rates, they clarify some of the first principles that go into creating these simulations, and the pressures of giving critical public health advice.

Guests
Professor Michael Baker FAFPHM (University of Otago)
Professor Tony Blakely (Melbourne School of Population and Global Health, University of Melbourne)
Professor Jodie McVernon FAFPHM (Director of Epidemiology, Doherty Institute)
