Environmental Epidemiology

Epidemiologists accumulate data from symptoms of previous medical history, laboratory testing exam finding, and recent treatments that trainees and training staff had received when carrying out a given task. The medical records are reviewed from training and at the different hospitals which include a list of trainees who were too sick to take part in routine training and medical charts of also patients with pneumonia are included from troop companies if many training camps (Health, 2013).

As it relates to the difficulties that Epidemiologists face around the world in gathering data on global diseases also to see how best they can aid in the fighting or control in the spread of these infectious diseases and formulate risk factors it can be

Environmental epidemiology has many unique features associated with it that makes these debates especially pertinent to it. A very large number of environmental exposures require prioritization, and the relative risks are usually very low. Furthermore, many environmental exposures can be addressed only by comparing populations rather than individuals, and the disruption of both local and global ecosystems requires us to develop new methods of study design. The population context is also very important to consider in risk management decisions because of the involuntary nature of most environmental exposures and the diversity of possible outcomes, both health- and no health-related. Studies at the individual or molecular level tend to focus the research hypotheses and subsequent interventions at that level, even when research and interventions at other levels may be more appropriate. Thus, only by starting from the population and ecosystem levels can we ensure that these are given appropriate consideration. Although better research is needed at all levels, it is crucially important to choose the most appropriate level, or levels, of research for a particular problem. Only by conducting research at all these levels and by developing further methods to combine evidence from these different levels can we hope to address the challenges facing environmental epidemiology
