Document Summary

Selected disease concepts in epidemiology: disease. Physiological or psychological dysfunction. Epidemiology deals with communicable and non communicable disease distribution, etiology, prevention, and control: communicable diseases. Transmitted directly or indirectly to person through contact, inhalation, or indigestion. Infectious agent goes from reservoir, portal of exit, mode of. Transmission, portal of entry, susceptible host: non- communicable diseases. Cannot be transmitted to others. E. g. diabetes, stroke, muscular dystrophy: health issues that are not diseases. Distribution, antecedents, and control of risk- taking behaviors: disease burdens. Host and agent are balanced on a triangle of environment. When out of balance health is compromised: holistic models of health. Look at factors that influence health vs disease. Health defined as state of well0being and positive functioning: not the lack of disease. Produces onset of disease. Disease process has begun but no overt signs or symptoms. In communicable diseases this includes incubation period: time between invasion and first development of symptoms.
