Health geography

Health geography is the application of geographical information, perspectives, and methods to the study of health, disease, and health care.

Overview
The study of health geography has been influenced by (re)positioning of medical geography within the field of social geography due a shift from a medical model to a social model in healthcare, which advocates for the redefinition of health and health care away from prevention and treatment of illness only to one of promoting well-being in general. Under this model, some previous illnesses (e.g., mental ill health) are recognized as behavior disturbances only, and other types of medicine (e.g., complementary or alternative medicine and traditional medicine) are studied by the medicine researchers, sometimes with the aid of health geographers without medical education. This shift changes the definition of care, no longer limiting it to spaces such as hospitals or doctor's offices. Also, the social model gives primacy to the intimate encounters performed at non-traditional spaces of medicine and healthcare as well as to the individuals as health consumers.

This alternative methodological approach means that medical geography is broadened to incorporate philosophies such as Marxian political economy, structuralism, social interactionism, humanism, feminism and queer theory.

History of health geography
The relationship between space and health dates back to Hippocrates, who stated that "airs, waters, places" all played significant roles impacting human health and history. A classic piece of research in health geography was done in 1854 as a cholera outbreak gripped a neighborhood in London. Death tolls rang around the clock and the people feared that they were being infected by vapors coming from the ground. John Snow thought that if he could locate the source of the disease, it could be contained. He drew maps showing the homes of people who had died of cholera and the locations of water pumps. He found that one pump, the public pump on Broad Street, was central to most of the victims. He figured that infected water from the pump was the culprit. He instructed the authorities to remove the handle to the pump, making it unusable. After that the number of new cholera cases decreased.

Areas of study
Health geography is considered to be divided into two distinct elements. The first of which is focused on geographies of disease and ill health, involving descriptive research quantifying disease frequencies and distributions, and analytic research concerned with finding what characteristics make an individual or population susceptible to disease. This requires an understanding of epidemiology. The second stream of health geography is the geography of health care, primarily facility location, accessibility and utilization. This requires the use of spatial analysis and often borrows from Behavioral economics.

Geographies of disease and ill health
Health geographers are concerned with the prevalence of different diseases along a range of scales from the local to global, and inspects the natural world, in all of its complexity, for correlations between diseases and locations. This situates health geography alongside other geographical sub-disciplines that trace human-environment relations. Health geographers use modern spatial analysis tools to map the diffusion of various diseases, as individuals spread them amongst themselves, and across wider spaces as they migrate. Health geographers also consider all types of spaces as presenting health risks, from natural disasters, to interpersonal violence, stress and other potential dangers.

Geography of health care provision
Although health care is a public good, it is not equally available to all individuals. Demand for public services is continuously increasing. People need advance knowledge and fastest prediction technology, that Health Geography offers. The latest example is Telemedicine
