Some of the books that I like about public health and epidemiology are The Coming Plague by Laurie Garrett and Spillover by David Quammen. These have a sense of adventure and cooperation in crisis times, where investigators/detectives try to find the cause of the disease (bacteria, parasite, virus, pollutant, …); the vector that spreads it (bat, mosquito, snail, pig, bird, rat, mouse,...); and the disruption in the ecosystem that pushed the disease onto humans (the rainforest homes of the mice cut down and turned into agricultural fields and then DDT killing off the cats that kept the mice away); and the cure (more cats to keep mice with the disease out of the village huts for Machupo Bolivian hemorrhagic fever) The bold parts are about the example of Machupo fever.

I also like Laurie Garrett's The Betrayal of the Public Trust about the way tax cuts have cut the programs that notice and respond to public health threats like antibiotic resistant bacteria, TB, bird flu, swine flu, Zika, H1N1, TB, horseshoe bat corona viruses, etc
