Symptoms of the disease are constantly present, and relapses may often occur. 14. They obstruct the local channels in that area. Infectious disease may also be due to the toxic product of an infectious agent, such as the toxin produced by Clostridium botulinum causing classical botulism. transmission of the pathogen; entry into the human body; adhesion of the pathogen to body cells (not explained) entry of the pathogen into cells (not explained) an immune response; recovery (briefly explained) The Host: (1) Clears the pathogen and recovers Use the knowledge of ayurveda to understand the six stages of disease progression, deep-rooted causes, and how to increase longevity and well-being. In certain other cases, a patient may eliminate the infectious agent from their body, but the immune system is damaged to such an extent that the patient could end up developing an autoimmune disease such as rheumatoid arthritis.

Pathology/ Disease. The incubation period the time form initial contact with the infectious agent to the appearance of the first symptoms.During the incubation period, the agent is multiplying at the portal of entry but has not yet caused enough damage to elicit symptoms. Diseases causing most morbidity and mortality today are chronic (cardiovascular, cancer, HIV, hepatitis C, etc.) The first section of the diagram corresponds to the period of Incubation, the time between the exposure to an infectious disease and its development.

Infectious disease - Infectious disease - Immune response to infection: When a pathogenic (disease-causing) microorganism invades the body for the first time, the clinical (observable) response may range from nothing at all, through various degrees of nonspecific reactions, to specific infectious disease.
