Emerging infectious diseases

       The relationship between natural disasters and emerging diseases is frequently misconstrued. The risk for outbreaks is often presumed to be very high in the chaos that follows natural disasters, a fear likely derived from a perceived association between dead bodies and epidemics. The recent resurgence of infectious disease mortality marks a third epidemiologic transition characterized by newly emerging, re- emerging, and antibiotic resistant pathogens in the context of an accelerated globalization of human disease ecologies. These transitions illustrate recurring sociohistorical and ecological themes in human–disease relationships from the Palaeolithic Age to the present day.
