If you’ve been laid low by a bug recently, and assuming you’re feeling better, you may feel the need to educate yourself on what viruses are and how they work. Even a simple question such as “Are viruses alive?” has no simple answer, we learn, as Dr Michael Mosley and Professor Alice Roberts explain some of the science behind these crippling bundles of biochemistry.

With the help of virologists, they’ll be finding out what viruses do to our bodies and how they spread. Mosley even has a sample of his blood sent to a Chinese lab, which holds a database of all known flu viruses, and learns that as a child he suffered from two of the most catastrophic flu outbreaks in modern times.


Every year in the winter months millions of Britons come down with colds, flu and stomach problems caused by viruses, with normally routine illnesses having the potential to turn lethal. Professor Alice Roberts and Dr Michael Mosley report on the latest outbreaks around the nation and, with the help of leading virologists, find out what viruses do to our bodies, examine how they spread and offer advice on what people can do to stay fit and healthy for the rest of the winter.
