Detailed explanation-1: -A pathogen interacts with the host and causes infection, leading to the development of disease in the host. A pathogen may be any harmful microbial agent such as a bacterium, virus, protozoa, fungus or helminth etc.
Detailed explanation-2: -An infection results when a pathogen invades and begins growing within a host. Disease results only if and when, as a consequence of the invasion and growth of a pathogen, tissue function is impaired.
Detailed explanation-3: -The incubation period occurs in an acute disease after the initial entry of the pathogen into the host (patient). It is during this time the pathogen begins multiplying in the host.
Detailed explanation-4: -The portal of entry refers to the manner in which a pathogen enters a susceptible host. The portal of entry must provide access to tissues in which the pathogen can multiply or a toxin can act. Often, infectious agents use the same portal to enter a new host that they used to exit the source host.
