Most applied epidemiologists are required to have a master's degree from a school of public health. Some research epidemiologists may need a Ph. D. Students should be meticulous, logical, culturally sensitive and able to work independently. Epidemiology graduate schools mostly base their programs on English, science and mathematics classes. In order to apply for admission to epidemiology programs, students must request admission by special arrangement. Some schools offer this degree through their School of Public Health (MPH). Life experience also factors into admissions criteria. Epidemiology Graduate Programs and Curriculum. Epidemiology graduate students can choose to specialize in areas such as: cardiovascular disease, cancer, clinical approaches, infectious disease, neurological issues and genetic problems. Most schools share the same basic educational curriculum: Biostatistics. Biochemistry. Molecular biology. Immunology. Disease and injury determinants. Genetic disease and disability factors. Behavioral studies. Health services research. Population studies. Environmental disease. Epidemiology Career Paths. Graduates can pursue jobs in a variety of industries. Applied epidemiologists, who usually work for State health agencies, respond to disease outbreaks, determining their causes and helping to contain them. Research epidemiologists study diseases in laboratories and in the field to determine how to prevent future outbreaks. Epidemiologist Salary and Future Job Outlook. According to the Bureau of Labor Statistics (BLS), the median annual wages for epidemiologists were $6. The factors that may affect an epidemiologist’s salary include certification, years of experience, type of employer and location. The BLS predicts a 1. A heightened awareness of bioterrorism and rare but infectious diseases, such as West Nile Virus or Avian flu, is expected to drive job growth. Epidemiology - Wikipedia, the free encyclopedia. Epidemiology is the study and analysis of the patterns, causes, and effects of health and disease conditions in defined populations. It is the cornerstone of public health, and shapes policy decisions and evidence- based practice by identifying risk factors for disease and targets for preventive healthcare. Epidemiologists help with study design, collection, and statistical analysis of data, amend interpretation and dissemination of results (including peer review and occasional systematic review). Epidemiology has helped develop methodology used in clinical research, public health studies, and, to a lesser extent, basic research in the biological sciences. Epidemiologists rely on other scientific disciplines like biology to better understand disease processes, statistics to make efficient use of the data and draw appropriate conclusions, social sciences to better understand proximate and distal causes, and engineering for exposure assessment. Etymology. However, the term is widely used in studies of zoological populations (veterinary epidemiology), although the term . Therefore, this epidemiology is based upon how the pattern of the disease cause changes in the function of everyone. History. Imhotep) is known as the father of medicine. The cure to the sickness was to remove or add the humor in question to balance the body. This belief led to the application of bloodletting and dieting in medicine. They were considered to be able to spread by air, multiply by themselves and to be destroyable by fire. In this way he refuted Galen's miasma theory (poison gas in sick people). In 1. 54. 3 he wrote a book De contagione et contagiosis morbis, in which he was the first to promote personal and environmental hygiene to prevent disease. The development of a sufficiently powerful microscope by Antonie van Leeuwenhoek in 1. Wu Youke (1. 58. 2- 1. His book Wenyi Lun (Treatise on Acute Epidemic Febrile Diseases) can be regarded as the main etiological work that brought forward the concept, ultimately attributed to Westerners, of germs as a cause of epidemic diseases (source: http: //baike. His concepts are still considered in current scientific research in relation to Traditional Chinese Medicine studies (see: http: //apps. Js. 61. 70e/4. html). Another pioneer, Thomas Sydenham (1. His theories on cures of fevers met with much resistance from traditional physicians at the time. He was not able to find the initial cause of the smallpox fever he researched and treated. In it, he analysed the mortality rolls in London before the Great Plague, presented one of the first life tables, and reported time trends for many diseases, new and old. He provided statistical evidence for many theories on disease, and also refuted some widespread ideas on them. John Snow is famous for his investigations into the causes of the 1. His identification of the Broad Street pump as the cause of the Soho epidemic is considered the classic example of epidemiology. Snow used chlorine in an attempt to clean the water and removed the handle; this ended the outbreak. This has been perceived as a major event in the history of public health and regarded as the founding event of the science of epidemiology, having helped shape public health policies around the world. His findings were published in 1. Disinfection did not become widely practiced until British surgeon Joseph Lister 'discovered' antiseptics in 1. Louis Pasteur. In the early 2. Ronald Ross, Janet Lane- Claypon, Anderson Gray Mc. Kendrick, and others. Epidemiology research to examine the relationship between these biomarkers analyzed at the molecular level, and disease was broadly named . Genetic variation is typically determined using DNA from peripheral blood leukocytes. Since the 2. 00. 0s, genome- wide association studies (GWAS) have been commonly performed to identify genetic risk factors for many diseases and health conditions. While most molecular epidemiology studies are still using conventional disease diagnosis and classification systems, it is increasingly recognized that disease evolution represents inherently heterogeneous processes differing from person to person. Conceptually, each individual has a unique disease process different from any other individual (. Studies to examine the relationship between an exposure and molecular pathologic signature of disease (particularly cancer) became increasingly common throughout the 2. However, the use of molecular pathology in epidemiology posed unique challenges including lack of research guidelines and standardized statistical methodologies, and paucity of interdisciplinary experts and training programs. To resolve these issues and advance population health science in the era of molecular precision medicine, . In MPE, investigators analyze the relationships between; (A) environmental, dietary, lifestyle and genetic factors; (B) alterations in cellular or extracellular molecules; and (C) evolution and progression of disease. A better understanding of heterogeneity of disease pathogenesis will further contribute to elucidate etiologies of disease. The MPE approach can be applied to not only neoplastic diseases but also non- neoplastic diseases. In observational studies, nature is allowed to . Conversely, in experimental studies, the epidemiologist is the one in control of all of the factors entering a certain case study. The identification of causal relationships between these exposures and outcomes is an important aspect of epidemiology. Modern epidemiologists use informatics as a tool. Observational studies have two components, descriptive and analytical. Descriptive observations pertain to the . However, analytical observations deal more with the . These types of studies, in which an astute clinician identifies an unusual feature of a disease or a patient's history, may lead to formulation of a new hypothesis. Using the data from the series, analytic studies could be done to investigate possible causal factors. These can include case control studies or prospective studies. A case control study would involve matching comparable controls without the disease to the cases in the series. A prospective study would involve following the case series over time to evaluate the disease's natural history. This technique has been extensively used in the study of adverse reactions to vaccination, and has been shown in some circumstances to provide statistical power comparable to that available in cohort studies. Case- control studies. It is a retrospective study. A group of individuals that are disease positive (the . The control group should ideally come from the same population that gave rise to the cases. The case- control study looks back through time at potential exposures that both groups (cases and controls) may have encountered. The statistic generated to measure association is the odds ratio (OR), which is the ratio of the odds of exposure in the cases (A/C) to the odds of exposure in the controls (B/D), i. OR = (AD/BC). Cases. Controls. Exposed. ABUnexposed. CDIf the OR is significantly greater than 1, then the conclusion is . If the OR is far less than one, then this suggests that the exposure is a protective factor in the causation of the disease. Case- control studies are usually faster and more cost effective than cohort studies, but are sensitive to bias (such as recall bias and selection bias). The main challenge is to identify the appropriate control group; the distribution of exposure among the control group should be representative of the distribution in the population that gave rise to the cases. This can be achieved by drawing a random sample from the original population at risk. This has as a consequence that the control group can contain people with the disease under study when the disease has a high attack rate in a population. A major drawback for case control studies is that, in order to be considered to be statistically significant, the minimum number of cases required at the 9. As the odds ratio approached 1, approaches 0; rendering case control studies all but useless for low odds ratios. For instance, for an odds ratio of 1. Cases. Controls. Exposed. Unexposed. 84. 10. For an odds ratio of 1. Cases. Controls. Exposed. Unexposed. 16. 52. Cohort studies. The study subjects should be at risk of the outcome under investigation at the beginning of the cohort study; this usually means that they should be disease free when the cohort study starts. The cohort is followed through time to assess their later outcome status. An example of a cohort study would be the investigation of a cohort of smokers and non- smokers over time to estimate the incidence of lung cancer. However, the point estimate generated is the relative risk (RR), which is the probability of disease for a person in the exposed group, Pe = A / (A + B) over the probability of disease for a person in the unexposed group, Pu = C / (C + D), i. RR = Pe / Pu... Case. Non- case. Total. Exposed. AB(A + B)Unexposed. CD(C + D)As with the OR, a RR greater than 1 shows association, where the conclusion can be read . The RR is a more powerful effect measure than the OR, as the OR is just an estimation of the RR, since true incidence cannot be calculated in a case control study where subjects are selected based on disease status. Temporality can be established in a prospective study, and confounders are more easily controlled for. However, they are more costly, and there is a greater chance of losing subjects to follow- up based on the long time period over which the cohort is followed. Cohort studies also are limited by the same equation for number of cases as for cohort studies, but, if the base incidence rate in the study population is very low, the number of cases required is reduced by . For epidemiologists, the key is in the term inference. Correlation is a necessary but not sufficient criteria for inference of causation.
