Emerging and epidemic infectious diseases have had a major effect on human history. We are just now coming to appreciate the mechanisms by which new strains emerge and the factors that permit their rapid spread within human populations. Cholera is a classic epidemic disease that causes periodic pandemics (possibly reflecting genetic changes in surface antigens of the microorganism) and seasonal epidemics that appear to be triggered by environmental factors. Citrus greening is a plant disease that kills citrus trees; a vector-borne bacterial disease, it is currently spreading rapidly across Florida. Control of these and other epidemic and emerging diseases may be difficult, particularly if the infection is already widespread in target populations. Any chance of successful control requires a comprehensive understanding of the pathogenesis and transmission pathways of the microorganism.
