What are some possible things that you as a disease outbreak expert can do to ?

Study the disease: see the reaction it causes (the end result), what it does to the body, what the major key genes in the disease are, see what reacts to it. You can study it until you find a cure for it, after that you can distribute the cure to the people affected by the outbreak.

also one way that you could study the outbreak is finding someone who is immune to the disease and seeing how they are immune to it.
