It deals with the study of what affects people within a given geographical area. Epidemiology is one of the pillars of public health that shapes decision making policies based on the evidence that exist within a given locality.

Impact of Epidemiology on the Health Professions
Despite epidemiology having side effects within a given population, it has impacted much on the health profession. One, Epidemiologists has brought more gain in experience to the health professions. They can now study the patterns, collections and statistically analyze data. Data analysis helps in the interpretation and distribution of results within peer and systematic review. Secondly, Epidemiology has led to the development of methodology in the biological science used in public health studies, basic research and clinical research.
Clinical trial is a case where individuals offer to test new devices or drugs. Medical practitioners use clinical trials to explore whether a new treatment functions and whether it is safe for human use. The nature of such studies is much needed to enable the development of new treatments for terminal, curable or preventable disease like Cancer. In general, clinical trial is used in the evaluation of a new treatment. An example of a well-known Clinical trial is at Yale Cancer Center. Since cancer has become a very common chronic disease worldwide, Yale Cancer Center is very much at the disposal of the patients who seek advanced treatments. The center is known to have technical experts in their laboratories who deal with animal studies. Before a new method of treatment in release to the patients, a lot of research must have been done. This thorough research is to ensure that the drug is not harmful to the patient’s life.

Second, investigations carried out at different levels highlights various geographical areas that need certain kind of studies. Investigations on a worldwide, national and local level helps in identifying different types of cancer and the health outcomes of mortality and morbidity. Additionally, investigations help in revealing characteristics of different population. Various areas have specific mortality and cancer incidences, this approach can only be arrived at if investigations are done at different levels. Last but not least, investigations also help in coming up with various approaches to be used in overcoming the epidemical disease.
Policy and Cost Issues That May Surround the Investigations into Populations
There are various policy and cost issues that engulf investigations in any population setup. Government policies are one of the factors that determine investigations in a given geographical area. These policies are rules and regulations that investigators have to adhere to while carrying out research in various geographical areas. Human rights are also another policy to be put into consideration. No persons should be compelled to engage in any research unwillingly. In terms of cost, it’s either the body that carries out investigation caters for the expenses or their various sponsors.
