pathogenesis

Pathogenesis refers to how a disease develops and progresses in the body. It involves understanding the processes and steps by which harmful agents, like bacteria, viruses, or toxins, cause damage to tissues and organs. This includes how the disease starts, spreads, and leads to the symptoms experienced. Essentially, pathogenesis explains the chain of events from the initial cause to the resulting health effects, helping healthcare professionals understand, diagnose, and treat illnesses more effectively.
