Definition Of Disease In The Context Of Vaccines And Immunity

It has long been known that in some illnesses Pandemic Survival Review such as measles, chickenpox and scarlet fever, one bout of the illness usually provides lifelong immunity. A second experience with measles or scarlet fever is extremely rare. Why is that so? That is because nature has gifted the human body with wonderful natural armor - an in-built immunity - that protects the body by kicking in after a bout of a particular disease.

Till modern science unraveled the secrets of the immune system, the concepts of medicine formulated in the 19thcentury were in part based on the understanding of medicine by the ancient Greek physician Hippocrates. According to Hippocrates, an illness manifests itself as signs and symptoms that travel from the inner vital organs and blood circulation to the outer surface of the body. These outer symptoms manifest themselves as visible symptoms such as a rash or discharge of blood, mucus or pus.

This 'throwing off' of an illness was considered a natural healing response which returned the body to a state of balance or equilibrium. And it took place only after the inner poisons produced by the disease were cooked and digested (pepsis) during the inflammatory process. Hippocrates's astute observations were further developed by modern science, which later uncovered the actual mechanisms of infection, inflammation and healing on these very same lines.
