pathogenesis

Pathogenesis refers to the process by which a disease develops and progresses within an organism. It encompasses the sequence of events and mechanisms that lead to the onset, progression, and outcomes of a disease or pathological condition.

Etiology: The study of the cause or causes of a disease, including genetic, environmental, infectious, immunological, and other factors that contribute to its development.

Pathophysiology: The study of how physiological processes are altered in disease states, including biochemical, molecular, and cellular changes that occur as a result of disease mechanisms.

Clinical manifestations: The signs and symptoms that characterize the disease, which may vary depending on the specific pathogenic mechanisms involved and the affected tissues or organs.

Progression: The sequence of events leading from initial exposure or onset to the development of symptoms, disease progression, and potential complications.

Understanding the pathogenesis of a disease is crucial for developing effective prevention strategies, diagnostic tests, and therapeutic interventions. It involves studying interactions between pathogens (if applicable), host factors, and environmental influences that collectively determine the course and severity of the disease.
