Epidemiology (the study of epidemics) is said that roots nearly 2,500 years ago and can be traced from Hippocrates through John Graunt, William Farr, John Snow, and others. In fact, epidemiology as a discipline has blossomed in World War II but much earlier in mid-1800s, many credits its origins to British physician John Snow and a deadly cholera outbreak in London, where Dr. Snow suspected that contaminated water might be to blame. Epidemiology, is identified as the study and analysis of the distribution (who, when, where and what), patterns and determinants of health and disease conditions in defined populations. It is a very powerful tool useful for understanding diseases outcomes caused by single, quantifiable toxins such as cigarette smoke and lately COVID-19.
The main methodological tool for epidemiology is observational science because it relies on systematic analysis and pattern recognition instead of on clinical experiments— and many cases this is the only ethical tool to use without harming or exposing healthy people to deadly bacteria, toxins, or viruses. Epidemiology thus aims to help us understand and fight diseases, make better choices, and live a healthier life.
Monitoring of critical public health indicators through the continuous, systematic collection, analysis, interpretation of measured data.
Field studies to evaluate, as systematically and objectively as possible, the relevance, effectiveness, efficiency and impact of treatment of a communicable disease.
Liaison and sharing of information to develop disease control strategies, regulations and care policy.
The clear and in-depth epidemiology interdisciplinary research.
A great example is the SARS2 pandemic and its impact on the social and economic life of us all. The strengthening of the effort for the development of a scientific observatory for the study and monitoring of the risk factors for causing various diseases in Crete will give significant benefits to our Region in human, social and economic level.
Understanding, prediction and evolution (frequency & distribution) of diseases and morbid conditions in humans.
Study and development of appropriate prediction models in epidemiological research.
Prevent & control major health crises. Today has already managed, for COVID-19 pandemic, to make available models for the evolution and prediction of the progression of the disease, with complete success.
Identification and causation of disease risk factors that are fundamental today, not only because they relate to health and life, but also because they profoundly affect economic and social wellness.
