Where did coronavirus really start? (spoiler: not a CIA lab)

There are a lot of conspiracy theories out there about the origins of coronvirus — was it invented by the US military? The US Democrats? Maybe even by aliens? Well... no. And the real answer will not surprise you (hint: it arose in Wuhan). In today's episode: * Where did coronavirus come from? * Should you pull your kid out of school? * How do you navigate social distancing in a share house? * What is contact tracing and how does it work? And Dr Norman Swan talks about a study which finds most COVID-19 infections in Wuhan were going under the radar — so what does that mean for us in Australia? Coronacast is a daily podcast that’s all about answering your coronavirus questions. If you want to send in a question, go to abc.net.au/coronavirus and we might answer it tomorrow on the podcast.
