Knowledge of the natural history of disease ranks alongside causal understanding in importance for disease prevention and control. Natural history of disease is one of the major elements of descriptive epidemiology. [2] As an example, the cartilage of the knee, trapeziometacarpal and other joints deteriorates with age in most humans ...
Widespread non-communicable diseases such as cardiovascular disease and cancer are not included. An epidemic is the rapid spread of disease to a large number of people in a given population within a short period of time; in meningococcal infections , an attack rate in excess of 15 cases per 100,000 people for two consecutive weeks is considered ...

In medicine, a natural history study is a study that follows a group of people over time who have, or are at risk of developing, a specific medical condition or disease. A natural history study collects health information over time to understand how the medical condition or disease develops and to give insight into how it might be treated.
One example of a naturalistic disease theory is the theory expressed in western medicine or biomedicine, which links disease and illness to scientific causes. This leaves any personal liability for the disease out of the equation, and the diseases are attributed to organisms such as bacteria or viruses , accidents, or toxic substances .

In some infectious diseases, the severity of symptoms has been shown to be dependent on specific genetic traits of the host. [6] [7] 4. Organisms that look alike but behave differently: In some cases a harmless organism exists which looks identical to a disease causing organism with a microscope, which complicates the discovery process.
