  3. 3. Natural history of the Disease<br />It is the natural evolution of any pathological process, from its beginning to its resolution, without any help of the man.<br />
  4. 4. Natural history of the Disease<br />Pre-Pathogenic period:it corresponds to the time in which the people are healthy, that is to say, are in balance with it’s atmosphere.<br />Pathogenic period:it corresponds at the beginning of the disease, even before the symptoms appear.<br />
  5. 5. Pre-Pathogenic period <br />In this period the three elements in a disease interacts, that is formed by:<br />Host<br />Environment<br />Agent<br />

Specific unspecific and specific<br />Mechanisms of the pathogenic agent local or systemic<br /> SUB-CLINIC STAGE<br />Entrancedoor: <br />Period of Incubation (period of latency, adaptation, reproduction, local expansion, histopathologic changes and/or systemic dissemination)<br />
  12. 12. Pathogenic Period<br />In anyone of these consecutive stages, before the death, the disease can be aborted, that is to say, to return to the Pre-Pathogenic Period.<br />
