When the deadly Ebola virus broke out in West Africa in 2014, scientists in the USA set to work analysing it. What they discovered would eventually lead to a treatment. Pardis Sabeti is a virologist at Harvard University and leads the team who sequenced the Ebola virus genome - she has been speaking to Ibby Caputo for Witness History.
