What Is Epidemiology? Epidemiological research helps us to understand how many people have a disease or disorder, if those numbers are changing, and how the disorder affects our society and our economy. The epidemiology of human communication is a rewarding and challenging field. Much of the data that epidemiologists collect comes from self-report—from answers provided by people participating in a study. For instance, an epidemiological study may collect data on the number of people who answer, “Yes” when asked if someone in their household has trouble hearing.

- The role of mathematical epidemiology is to model the establishment and spread of pathogens. A predominant method of doing so, is to use the notion of abstracting the population into compartments under certain assumptions, which represent their health status with respect to the pathogen in the system.

A Guide to Careers in Epidemiology Epidemiologists are scientists who study diseases within populations of people. In essence, these public health professionals analyze what causes disease outbreaks in order to treat existing diseases and prevent future outbreaks. Thanks to this, epidemiologists are considered “disease detectives” of the public health world. The following article is for those interested in careers in epidemiology.

- The key elements are: an understanding of disease processes (like what a vector is), knowledge of data or information available (like numnber of infections), knowing what a Geographic Information Systems (GIS) is (to analyze patterns).and an understanding of social sciences (that can indicate risk factors). Epidemiology is the study of the spread of disease. It helps scientists to predict how far a disease will spread, how much damage it may do, and plan treatment, the crea … tion of vaccines, and so forth. The current preparations for swine flu were a result of epidemiological studies.  . 7 people found this useful.

Chapter 1. What is epidemiology? All findings must relate to a defined population. A key feature of epidemiology is the measurement of disease outcomes in relation to a population at risk. The population at risk is the group of people, healthy or sick, who would be counted as cases if they had the disease being studied.
