Pathogenesis refers to the biological mechanism that leads to the development of a disease. It involves the interaction between pathogens, such as bacteria or viruses, and the host's immune system. Understanding pathogenesis helps researchers identify how diseases progress and how they can be treated or prevented. The study of pathogenesis encompasses various factors, including genetic predisposition, environmental influences, and the specific characteristics of the pathogen. By examining these elements, scientists can develop targeted therapies and vaccines, ultimately improving public health outcomes and disease management strategies.
