Welcome to the living surfaces of infectious diseases! I have started this blog for two reasons. First, I want to transfer the content of my infectious disease course at SUNY, Downstate to a wider audience. Second, I want to engage a discussion of the processes of infectious disease from a landscape epidemiology perspective. Our physical and social landscapes define a dynamic, living surface on which we live. This "living surface" also defines the terrain on which we experience health or illness. Comprised of complex ecologies, geographies, social structures, interpersonal interactions, and highly evolved pathogen biology, the relationships between humans and infectious organisms are simultaneously both nuanced and extravagant in their epidemiology. This blog seeks to explore the nuance and extravagance together in an effort to 1) arrive at a clearer understanding of the human-pathogen relationships, and 2) to discuss the targeting of control and prevention of disease in human populations.
