Virology and evolutionary biologist Professor Eddie Holmes takes Dr Karl time travelling to visit a deadly virus. Many of today's treatments took thousands of years to develop.  Smallpox proved to be a tough virus to manage but it also taught us how to fight back. From skin scratching to cows, the American Civil War, Baltic mummies and DNA -  Science finally stopped smallpox in its tracks.  @EdwardCHolmes https://drkarl.com/ Note: episode recorded in late May 2020 using data available at the time
