Epidemiology Wikipedia. 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.

Background Public reporting and pay for performance are intended to accelerate improvements in hospital care, yet little is known about the benefits of these methods.

Major areas of epidemiological study include disease causation, transmission, outbreak investigation, disease surveillance, forensic epidemiology, Occupational epidemiology, screening, biomonitoring, and comparisons of treatment effects such as in clinical trials. 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. EtymologyeditEpidemiology, literally meaning the study of what is upon the people, is derived from Greekepi, meaning upon, among, demos, meaning people, district, and logos, meaning study, word, discourse, suggesting that it applies only to human populations. However, the term is widely used in studies of zoological populations veterinary epidemiology, although the term epizoology is available, and it has also been applied to studies of plant populations botanical or plant disease epidemiology. The distinction between epidemic and endemic was first drawn by Hippocrates,3 to distinguish between diseases that are visited upon a population epidemic from those that reside within a population endemic. The term epidemiology appears to have first been used to describe the study of epidemics in 1. Spanish physician Villalba in Epidemiologa Espaola. Epidemiologists also study the interaction of diseases in a population, a condition known as a syndemic. The term epidemiology is now widely applied to cover the description and causation of not only epidemic disease, but of disease in general, and even many non disease, health related conditions, such as high blood pressure and obesity. Therefore, this epidemiology is based upon how the pattern of the disease cause changes in the function of everyone. HistoryeditThe Greek physician Hippocrates is known as the father of medicine,56 sought a logic to sickness he is the first person known to have examined the relationships between the occurrence of disease and environmental influences. Hippocrates believed sickness of the human body to be caused by an imbalance of the four humors air, fire, water and earth atoms. Modern Methods For Robust Regression Pdf Editor' title='Modern Methods For Robust Regression Pdf Editor' />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. He coined the terms endemic for diseases usually found in some places but not in others and epidemic for diseases that are seen at some times but not others. Modern eraeditIn the middle of the 1. Verona named Girolamo Fracastoro was the first to propose a theory that these very small, unseeable, particles that cause disease were alive. They were considered to be able to spread by air, multiply by themselves and to be destroyable by fire. In this way he refuted Galens 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. 21. 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. 70e4. html. Another pioneer, Thomas Sydenham 1. Londoners in the later 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. John Graunt, a haberdasher and amateur statistician, published Natural and Political Observations. Bills of Mortality in 1. 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. He began with noticing the significantly higher death rates in two areas supplied by Southwark Company. 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. Crack Internet Cafe 4.9.5. 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. However, Snows research and preventive measures to avoid further outbreaks were not fully accepted or put into practice until after his death. Other pioneers include Danish physician Peter Anton Schleisner, who in 1. Vestmanna Islands in Iceland. Another important pioneer was Hungarian physician Ignaz Semmelweis, who in 1. Vienna hospital by instituting a disinfection procedure. 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. Another breakthrough was the 1. British Doctors Study, led by Richard Doll and Austin Bradford Hill, which lent very strong statistical support to the link between tobacco smoking and lung cancer. In the late 2. 0th century, with advancement of biomedical sciences, a number of molecular markers in blood, other biospecimens and environment were identified as predictors of development or risk of a certain disease. Epidemiology research to examine the relationship between these biomarkers analyzed at the molecular level, and disease was broadly named molecular epidemiology. Tdu Car Pack Pc on this page. Specifically, genetic epidemiology has been used for epidemiology of germline genetic variation and disease. 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.
