Why do some people die from coronavirus while others don't know they even have it?

In this episode, we take a closer look at why some people become seriously ill with Covid-19 and why so many of them are dying. The outbreak has claimed the lives of people of all ages - but are there certain groups who are succumbing more to the virus than others?
