NURSING ANM AND GNM

Detailed explanation-1: -Susceptibility of a host depends on genetic or constitutional factors, specific immunity, and nonspecific factors that affect an individual’s ability to resist infection or to limit pathogenicity. An individual’s genetic makeup may either increase or decrease susceptibility.

Detailed explanation-2: -Host factors include those that are largely fixed (such as demographics, ancestry, and genetics) and those that are influenced by early life exposure to other risk factors. The risk of ARF is strongly influenced by specific demographic factors, particularly age and ethnicity (discussed further later).

Detailed explanation-3: -Those characteristics are: Infectivity: The ability to enter and multiply in the host. Pathogenicity: The ability to produce a specific clinical reaction after infection occurs. Virulence: The ability to produce a severe pathological reaction.
