What factors contribute to the increased risk of fungal infections in older adults according to the chapter?

The increased risk of fungal infections in older adults is due to a decline in the immune system with aging, increased comorbidities, use of multiple medications, and potential decline in personal hygiene.

Older adults are more susceptible to fungal infections primarily because their immune systems weaken with age. This immunosuppression makes them more vulnerable to infections that might otherwise be controlled. Additionally, older adults often have more comorbidities and take multiple medications, which can further compromise their immune response. A decline in personal hygiene, which can occur due to functional impairments, also contributes to the risk of fungal infections in this population. These factors combined create an environment where fungal infections can thrive more easily in older adults.
