Every year, researchers discover two or three entirely new pathogens: the viruses, bacteria and microparasites that sicken and kill people.
While some of these discoveries reflect better detection methods, genetic studies confirm that most of these pathogens are indeed new to the human species. Even more troubling, these diseases are appearing at an increasing rate.
Despite the novelty of these particular infections, the primary factors that led to their emergence are quite ancient. Working in the field of anthropology, I have found that these are primarily human factors: the ways we feed ourselves, ...
