Many of the causes already known today were studied under the etiology of things and it is very likely that at this time this study is being applied to more disorders.

History in medicine

Since ancient times, medical professionals apply certain techniques to quickly understand what is happening with a patient. They are trained to ask the right questions for an early diagnosis before attempting more technical analysis.

Already in the 19th century, various instruments began to be used to make diagnoses or determine causes of diseases in the most precise way. At present, the field of robotics and artificial intelligence in medicine is more advanced, achieving great support for specialists.

How does the etiological study work?

In summary, it has been established that a disease includes three factors to evaluate: a host (the organism that becomes ill), an agent (what causes the disease) and an environment (the environment). The three factors, according to the etiology, must be concurrent in space and time for the disease to manifest itself.
