Older adults are most at risk for which type of diseases?

• A. Chronic non-communicable diseases
• B. Genetic disorders
• C. Acute injuries
• D. Communicable diseases

Answer: (D)

Older adults have immune aging, meaning the immune system becomes less effective with age. This makes them more susceptible to infections and more likely to have serious complications from communicable diseases such as influenza, pneumonia, and other contagious illnesses. In addition, chronic health conditions common in older adults can worsen infections and recovery, reinforcing why infections are a particularly important risk in this group. While chronic non-communicable diseases are indeed prevalent in older people, the age-related vulnerability to acquiring and suffering from infections is what makes communicable diseases the most relevant risk category here. Vaccination and infection prevention are especially important to protect older adults.
