What Is Epidemiology? About The Study Of Science
EPIDEMIOLOGY – In this topic, we are going to know and learn a scientific study about health conditions of population called epidemiology.
It refers to the study and analysis of the distribution (referring to the who, when and where), patterns, and determinants of health and disease conditions in certain populations.
It is the public health’s cornerstone and shapes policy decision and practice that are evidence-based by spotting risk factors for disease and aims for preventive health care.
People who study epidemiology are called epidemiologists. The term, which literally means the “the study of what is upon the people”m, came from three Greek words epi (ἐπί) which means “upon, among”; demos (δῆμος) which means “people, district”, and logos ( Λόγος ), which means “study, word, discourse”, hence, this applies only to human populations.
It was said to have been first used to define the study of epidemics on 1802 by Villalba , a Spanish physician in Epidemiología Española. Epidemiologists also study the interaction of diseases in a population, which is known as syndemic.
Nowadays, the term is widely used to cover the description and causation of diseases, generally, rather than just epidemic disease. It also covers non-disease, health-related conditions, such as high blood pressure, depression and obesity.
