It derives from the Greek "aitiologia" which means "to give a reason for"; Etiology is the science in charge of studying and analyzing the causes or origins of things. This concept is used mostly in medicine to detect the cause of diseases starting from the point of having known their effects and the reason for them. From the beginning in which people visit the doctors, he asks the rigorous questions to detect the cause of the disease the patient is attending and that is where the concept of Etiology comes into full force, which the doctor will use to know where, when, and from when you feel the symptoms.
For the different diseases for which a specific cause is not known, it is said that their etiology is not known at the time of diagnosing the patient or studying the samples as the case may be. Etiology is essential in the case of an unknown disease or an outbreak which is new because once the origin and cause is detected, it will be easier to search for a cure or preventive medicine.
According to the history of mankind, Etiology was the golden age of so-called Islam because it was the moment where serious studies of this science began to determine, discover, treat and eradicate the diseases that we know today as epidemics or pandemics..
