They looked not only at the circumstances surrounding the deaths of the two individuals, but cases where trainees excused from training due to sickness. Epidemiology collects information on trends for diseases and other public health issues, collates it, analyzes it and produces reports for future study (2). Epidemiology might look at why a condition is prevalent in one population and not another, and the potential risks of that condition spreading. Read more about the history of climate change. 30 mins. It can be argued that modern epidemiology has its roots in biology and zoology, where some of the earliest instances of disease study began. The concept of bias is the lack of internal validity or incorrect assessment of the association between an exposure and an effect in the target population in which the statistic estimated has an expectation that does not equal the true value. Medical science has grown exponentially in the last century; the birth of modern medicine has given us profound improvements to our general health, lifestyle and longevity. Some epidemiologists may examine life span, stress rates, why some cities or areas of a city have higher levels of workplace sickness and higher than normal levels of domestic violence (3).

This was not an only case and recent studies of the spread of Ebola (in Africa in 2014) and Zika (in South America in 2015) have demonstrated further precisely why the study of instances of diseases, illness and other conditions is just as important as treatment. It works alongside pathology and other branches of medical science in understanding why a condition (including contagious diseases, but not exclusively so) is in one geographical area and not another, and what risk factors might lead to it spread.

He also invented the life table, a system still used in a range of sciences today but particularly in those who study instances of disease. Where movement used to be a natural barrier to the spread of disease, it will not become its greatest ally.

For epidemiology, there is a direct threat that areas that have seen diseases eradicated or those areas that have never experienced those diseases. A flaw in measuring exposure, covariate , or outcome variables that results in different quality (accuracy) of information between comparison groups. Studies have been carried out for the southern US states and southern Europe (34) into the potential threat of malarial mosquitoes, Lyme disease, dengue fever and encephalitis moving up from the south to climes more suited to their survival.
