More than 100 years ago, tens of millions of people died in an influenza pandemic.
The virus spread quickly and had a high mortality rate. More than a third of the world's population was infected.
So what can we learn from the 1918 pandemic?
On the show today:
* How does the virus kill you?
* How do you disinfect your stuff to try and keep it coronavirus free?
* Why 18 months to develop a coronavirus vaccine?
* How do I get rid of infected waste like tissues and masks?
And Dr Norman Swan explains how a 13 year old study on a 100 year old pandemic might have some interesting lessons.
