With the exception of a few tropical medicine schools worldwide, current medical education programs include almost no discussion of the interface between infectious diseases and entomology. That is why this book was initially published in the first edition almost 25 years ago. The fourth edition of this valuable infectious disease entomology book updates all existing chapters with the newest scientific developments described in the medical and entomological literature, in addition to expanding existing topics from precious editions and adding new ones, including: pests involved in mechanical disease transmission; mites in clinical medicine; the newest controversies in Lyme disease; the newest malaria and dengue vaccines; highly neglected vector-borne diseases; where to go for help with arthropod questions.
