Norman Swan made a big call in predicting that Victoria will start to see a reduction in coronavirus cases by next week, but not everyone agrees with him. Some health experts say it's more likely that the state will experience a wide curve, rather than a sharp decline. Ultimately, it'll come down to how many unknown mystery cases there are in the community. So is Norman sticking by his prediction? On today's show: * How sure is Norman about his big prediction? * What did we learn from SARS-CoV-1? Can we apply any knowledge from that? * Can you get COVID-19 multiple times within a short time frame? * If I can smell cigarette smoke and if I inhaled it from someone who was infected could I get sick? * What is "pool testing"? Why don't we use it in Australia? * Does UVC light effectively kill airborne coronavirus?
