Etiology is the have a look at of causation or origination. The word is derived from the Greek extra absolutely, etiology is the study of the reasons, origins, or reasons behind the way that things are, or the way they feature, or it can talk over with the causes themselves. The word is typically utilized in medication (referring to reasons of ailment) and in philosophy, however also in physics, psychology, authorities, geography, spatial evaluation, theology, and biology, in reference to the reasons or origins of various phenomena 

Introduction 

Within the beyond, whilst many physical phenomena had been now not nicely understood or when histories were not recorded, myths frequently arose to offer etiologies. Therefore, an etiological fantasy, or origin fantasy, may be a fantasy that has arisen, been informed over time or written to offer an evidence for the origins of various social or natural phenomena. For example, Virgil's Aeneid is a country wide myth written to explain and glorify the origins of the Roman Empire. In theology, many faiths have creation myths explaining the origins of the arena or its courting to believers.

In medicinal drug, the etiology of an contamination or condition refers back to the common research to determine one or more elements that come collectively to motive the illness. Relatedly, when disorder is vast, epidemiological studies inspect what related elements, consisting of place, intercourse, publicity to chemicals, and lots of others, make a population more or much less in all likelihood to have an infection, situation, or sickness, consequently supporting determine its etiology. Sometimes determining etiology is an imprecise system. Inside the past, the etiology of a common sailor's disorder, scurvy, was long unknown. When large, ocean-going ships were constructed, sailors began to put to sea for lengthy intervals of time, and often lacked sparkling fruit and veggies. without understanding the appropriate reason, Captain James cook dinner suspected scurvy became due to the dearth of vegetables inside the weight-reduction plan. Primarily based on his suspicion, he compelled his crew to consume sauerkraut, a cabbage coaching, each day, and primarily based upon the positive outcomes, he inferred that it prevented scurvy, even though he did now not recognize exactly why. It took about another hundred years to find out the appropriate etiology: the dearth of vitamin C in a sailor's weight-reduction plan.

An etiological fantasy, or foundation delusion, is a fantasy supposed to explain the origins of cult practices, herbal phenomena, proper names and so forth. For example, the decision Delphi and its associated deity, Apollon Delphinios, are defined within the Homeric Hymn which tells of the way Apollo, inside the form of a dolphin (delphis), propelled Cretans over the seas to lead them to his priests. Whilst Delphi is truly related to the word delphus ("womb"), many etiological myths are further primarily based on folk’s etymology (the term "Amazon", as an example). Within the Aeneid (published circa 17 BC), Virgil claims the descent of Augustus Caesar's Julian clan from the hero Aeneas thru his son Ascanius, also called Iulus. The tale of Prometheus' sacrifice trick at Mecone in Hesiod's Theogony relates how Prometheus tricked Zeus into selecting the bones and fats of the first sacrificial animal instead of the meat to justify why, after a sacrifice, the Greeks offered the bones wrapped in fat to the gods whilst retaining the meat for themselves. In Ovid's Pyramus and This be, the foundation of the coloration of mulberries is explained, because the white berries grow to be stained purple from the blood gushing forth from their double suicide.

Further thinking in epidemiology turned into required to differentiate causation from affiliation or statistical correlation. Events may arise collectively without a doubt because of risk, bias or confounding, in place of one occasion being because of the alternative. It is also essential to understand which event is the purpose. Cautious sampling and size are more vital than state-of-the-art statistical evaluation to decide causation. Experimental proof involving interventions (providing or getting obviate the meant reason) offers the foremost compelling proof of etiology.

Related to this, sometimes numerous symptoms continually seem collectively, or more frequently than what may be expected, even though it's miles recognized that one cannot reason the opposite. Those situations are called syndromes, and generally it is assumed that an underlying condition should exist that explains all the signs and symptoms.

Other instances there are not a single reason for a sickness, but alternatively a sequence of causation from an initial trigger to the development of the scientific ailment. An etiological agent of ailment can also require an independent co-thing, and be concern to a promoter (will increase expression) to purpose disorder. An instance of all of the above, which turned into identified past due, is that peptic ulcer disorder can be prompted via stress, calls for the presence of acid secretion inside the belly, and has primary etiology in Helicobacter pylori contamination. Many continual illnesses of unknown purpose can be studied on this framework to explain more than one epidemiological institutions or risk factors which may or might not be causally associated, and to are looking for the real etiology
