Which of the following is NOT listed as a factor influencing infection prevention?

• A. Exercise frequency
• B. Age
• C. Nutritional status
• D. Stress

Answer: (A)

Infection prevention is guided by host-related factors that directly affect immune defense. Age, nutritional status, and stress are recognized because they influence how well the body can fight infection and heal. Aging can weaken immune responses and slower recovery; poor nutrition impairs immune cell function and tissue repair; and stress can raise cortisol, suppressing immunity and increasing infection risk. These factors are commonly considered when planning prevention strategies. Exercise frequency, while beneficial for overall health and immune resilience, isn’t typically cited as a direct factor in infection prevention guidelines, so it isn’t listed as influencing infection prevention.
