Question

All of these are factors in why infection does not always occur except

A) Pathogen virulence
B) Immune response
C) Host susceptibility
D) Immunization

Answer 1

Pathogen virulence, host susceptibility, and immunization are all factors that can influence why infection does not always occur.

Step-by-step explanation:

The factors that can contribute to why infection does not always occur include:

• Pathogen virulence: This refers to the ability of a pathogen to cause host damage. Not all pathogens have the same level of virulence and some may have factors that allow them to evade immune responses.
• Host susceptibility: Some individuals may be more susceptible to infections due to preexisting conditions or genetic factors that affect their immune response.
• Immunization: Immunization can provide protection against specific pathogens, reducing the likelihood of infection.

The outcome of an infection depends on the interactions between the virulence factors of the pathogen and the immune defenses of the individual. Understanding these factors can help identify at-risk individuals and develop preventive interventions.
