Malaria and illegal gold mining

My guest today writes, "In many places around the world, malaria is closely linked to illegal gold mining" in a recent article in the BMC blog, BugBitten titled, "A story of two fevers: when malaria is the price of gold". What is malaria and how is it linked to illegal gold mining? Joining me today to look at this huge public health problem in certain parts of the world is Karina Mondragon-Shem, PhD. Dr Mondragon-Shem is a vector biologist who specializes in the ecoepidemiology and social impact of tropical diseases.
