Infections can lead to disease, which causes signs and symptoms resulting in a deviation from the normal structure or functioning of the host. WebStages of Pathogenesis. To cause disease, a pathogen must successfully achieve four steps or stages of pathogenesis: exposure (contact), adhesion (colonization), invasion, and infection. The pathogen must be able to gain entry to the host, travel to the location where it can establish an infection, evade or overcome the host’s immune response ...
