They found no association. At the end of an epidemic, a disease spreads at an increasing rate and then abruptly disappears. Diseases that are due mostly to environmental changes, increased population densities, and pollution that result from modernization in third world nations are referred to as:. Modern medicine has at times been responsible for causing health problems. Malnutrition has been essentially eliminated in the United States. Persistent undernourishment among children rarely results in serious health problems.

Return to Menu. On the undergraduate level, most epidemiologists have backgrounds in public health, biology, medicine and statistics. Typical careers for epidemiologists revolve around either conducting research or applying information and conclusions gathered from the research. Epidemiologists that conduct research are usually employed by universities or in conjunction with government organizations, such as the Centers for Disease Control and Prevention and the National Institutes of Health. Epidemiologists who apply knowledge obtained from research usually work with local governments and organizations directly tackling public health issues.

Job duties of an epidemiologist typically revolve around gathering medical and health information from the field, research or historical data, analyzing the data collected and presenting the findings. The findings can then be used to develop public health initiatives or discover how diseases originate, spread and can be treated. Even though humans are living longer and many diseases are no longer harming humanity the way they used to, epidemiologists are still important today. The specific day-to-day job duties of an epidemiologist differ depending on the organization they work for and whether they primarily focus on research or the application of research to public health issues.

However, there are basic tasks that apply to most epidemiologists, regardless of their primary area of focus.

The data can be historical, analyzed in ways not previously anticipated, or contemporary, acquired from a recently completed research study or clinical trial.

Management or development of public health initiatives based on new research data and analysis. Presentation of findings resulting from research or public health programs to members of the public, government and private organizations.

For a deeper understanding of what an epidemiologist does, it helps to go right to the source.

David H. Though Dr.


Schwartz does not have a degree in epidemiology, the work that he does relates very strongly to the field. The following interview offers a unique perspective of typical work done by an epidemiologist. After obtaining my PhD in neuroscience, I began to realize that there is a need for the ability to rigorously evaluate scientific information and to apply that analysis to a variety of venues, including legal actions, the regulatory arena and public policy.

I was granted a PhD in neuroscience from Princeton University. The process of obtaining a PhD helped provide me with a deep and meaningful understanding of how science is conducted and properly interpreted. I use these fundamental principles every day in my work. Reviewing and evaluating the rigor of scientific information. This includes the study design, conduct and then the interpretation of the study findings.

Ultimately, we need to align the evidence with the real-world problem and develop defensible arguments that are consistent with the scientific evidence. I would recommend that you focus on your training and try to develop a deep and nuanced understanding of the scientific method. In the United States, the healthcare industry is booming.

With improvements in medical records and information technologies, such as Big Data, epidemiologists will have more opportunities to analyze medical information and will be able to do so on a level not previously possible.

Why the seemingly low demand?

Lesson 5: Public Health Surveillance

The primary reason seems to be that demand for epidemiologists originates at the local and state government level. Unlike private organizations and the federal government, local and state governments are governed by more strict budgetary limitations. This recent trend of fiscal restraint at the state and local government level also explains why the United States Bureau of Labor and Statistics estimated that the epidemiologist job growth from to was 24 percent. In the two years between and , the job growth estimate or epidemiologists dropped by more than half.

What also occurred during that same two-year period? Strict austerity measures were put in place by state and local governments across the nation. Therefore, the job growth of epidemiologists revolves largely around the fiscal health of state and local government.

However, the importance of what an epidemiologist does can be seen in their national unemployment rate. According to the Bureau of Labor and Statistics, the national unemployment rate was 5. The national unemployment rate of health services professionals, as a whole, was 4 percent. However, the national unemployment rate of epidemiologist was only 1. Even though the overall job growth prospects for epidemiologists as a whole is anticipated to grow 10 percent between and , one of the primary factors in that estimate is the assumption that states and municipalities will continue to keep government spending at a minimum.

However, epidemiologists can often find work in related fields.
