Which statement best explains why infections may be identified late in older adults?

• A. Older adults always have fever with infection.
• B. The older adult might have an advanced infection before it is identified.
• C. Aging protects against infection, so signs are mild.
• D. Infections in older adults occur only with alternative symptoms.

Answer: (B)

In older adults, infections often present with vague, non-specific changes rather than the classic signs. The aging immune system may not mount a strong fever or visible inflammatory response, so fever can be absent or subtle. Baseline issues like confusion, fatigue, decreased function, loss of appetite, dehydration, or falls can mask the onset of infection and lead caregivers to attribute changes to aging or chronic illness. Because these subtle cues can precede more obvious illness, an infection may already be advanced by the time it’s recognized. This explains why infections are frequently identified late in older adults.
