ANTC67H3 Lecture Notes - Lecture 1: Demography, Etiology, Syphilis
Document Summary
Epidemiology: the study of how a disease is distributed in populations and the factors that influence or determine this distribution. The distribution of a disease includes whether the disease increases or decreases over time, as well as who gets the disease and who doesn"t. Objectives: to identify the etiology of a disease and the relevant risk factors. Etiology refers to the cause of a disease. In wyoming, a risk factor for contracting plague is hanging around the owner of the infected cat: to determine the extent of the disease found in the population. During the measles outbreak in the gta, only 4 cases made headlines. This is misleading in terms of the extent of measles found in the gta. Measured via the prevalence rate of the disease. (# of existing cases/the population at risk: to study the natural history and prognosis of the disease. Tuberculosis comes from a bovine, or in other words, a cow.
