NURSING ANM AND GNM

Detailed explanation-1: -Pathogenesis is the process by which an infection leads to disease. Pathogenic mechanisms of viral disease include (1) implantation of virus at the portal of entry, (2) local replication, (3) spread to target organs (disease sites), and (4) spread to sites of shedding of virus into the environment.

Detailed explanation-2: -Pathogenesis refers to the sequence of events during the course of an infection within the host, and the mechanisms giving rise to these events. It includes entry of the virus into the body, multiplication and spread, the development of tissue damage, and the production of an immune response.

Detailed explanation-3: -Each disease entity develops through a series of mechanistic chemical and cellular steps. This stepwise process of disease development is referred to as its pathogenesis (from the Greek word meaning generation of suffering).

Detailed explanation-4: -Stages of Pathogenesis. To cause disease, a pathogen must successfully achieve four stages of pathogenesis to become an infection: exposure, adhesion (also called colonization), invasion, and infection.

Detailed explanation-5: -: the origination and development of a disease.
