Pathogenesis is the development of a disease from onset to final stages, important for identifying and treating diseases. It allows doctors to determine the cause and stage of a disease, and can provide insight into disease spread and prevention. It intersects with pathophysiology and epidemiology, and is critical in studying new and emerging diseases.
Pathogenesis is the development of the disease, from the initial onset of the disease to its final stages. The study of pathogenesis is important for medical professionals, as it helps them identify and treat disease. It is also part of the work of laboratory sciences dealing with cures and cures for disease, as each stage of development represents a potential chance to halt disease progression.
The term “pathogenesis” comes from the Greek words for “disease” and “beginning”. The origins of the disease are the first step in the pathogenesis, as are the progressive changes that occur in the body as the disease takes hold and begins to affect the body. For example, when someone is cut and the wound is colonized with Staphylococcus bacteria, the bacteria cause inflammation as they begin to spread, eventually leading to infection. Every step from cutting to full-blown infection is part of development.
There are a number of uses for the study of pathogenesis. In the case of individual patients, it allows a doctor to determine what has caused a disease and how the disease can be treated. Being able to identify the stage reached by a disease can also be important for a doctor who provides medical care, as in the case of an oncologist who wants to determine the severity of a cancer.
Studying disease development can also provide insight into the ways in which diseases spread and potentially help develop a program designed to slow the spread of disease. In the example of an infected cut above, for example, infection may have been prevented by regularly cleansing the wound with an antibacterial soap, a procedure widely used in homes and hospitals around the world to reduce the risk of infection. This field is also a critical part of studying new and emerging diseases, as these diseases cannot be effectively fought without understanding where they come from.
A number of medical fields intersect with pathogenesis, including pathophysiology, the study of changes caused in the body by the progress of disease, and epidemiology, the study of how disease evolves and moves through populations. The study of disease development is especially important to members of the medical profession, as it enables them to take steps to prevent, diagnose and treat a wide variety of diseases. Even many laymen are familiar with the pathogenesis, as is the case with people familiar with the progression of recurrent sinus infections, or people who wash their hands to reduce exposure to agents that could cause disease.
