Which of these is NOT an infectious disease?
Correct Answer: A. Diabetes
Explanation: Diabetes is the correct answer because it is a non-infectious, chronic metabolic disorder caused by genetics, lifestyle factors, or environmental triggers rather than pathogens. Unlike measles, malaria, and cholera, which are infectious diseases transmitted through viruses, parasites, or bacteria, diabetes cannot be spread from person to person. It occurs when the body cannot properly produce or use insulin, leading to elevated blood sugar levels. While people with diabetes may be more susceptible to contracting infections, the condition itself is categorized as a non-communicable disease.
