The difference is major since the symptom is the expression of a genetic and epigenetic history. The investigative tools used allow us to know how to modify a situation. The genetic background is the sum of a genetic, environmental, family and cultural heritage. According to all these criteria and clinical measures, we can make a very judicious and effective prevention to delay and even prevent the occurrence of debilitating diseases.

In this research the following questions are asked:

• What is the infectious agent behind the symptoms or diseases?

• What is the genetic background that feeds this infectious?

The benefit of this new strategy is the rapid improvement of the patient's symptoms.
