The infectious disease landscape changes rapidly; infectious disease research must do the same.
New infectious diseases (IDs), such as SARS and Zika virus, are continuously emerging from zoonotic reservoirs. Older IDs such as malaria and tuberculosis often re-emerge to create public health concerns.
"Amongst disciplines in medicine, infectious disease requires knowledge of the animal world because so many infections cross from animals to humans, and the microbial world. Therefore, we are challenged to know about the biology of many different arms on the tree of life." - David Koelle, MD
