Document Summary
Study of factors related to the occurrence and distribution of disease within a population. Classical - focuses on discovering risk factors that might prevent or delay disease, injury or death within a population - focus on community. Clinical epidemiology - specifically focuses on population within a health care setting. Focus is on patients who are at risk or already afflicted by disease. Infectious disease epidemiology is focused on contagious diseases and which is heavily dependent on lab work. Chronic disease is focused on diseases which are more often an outcome of social-environmental factors. Sedentary lifestyle increases risk for coronary heart disease; smoking increases risk for lung cancer. Some diseases (e. g. tb, hiv) are considered both chronic and infectious. Etiology refers to the cause and origin of disease. Following the progression of a disease is referred to as the natural history of disease. The main purpose of population health interventions is to alter this natural history, either through prevention or treatment.
