Question

Which of the following is NOT a communicable disease?

1. A. Tuberculosis
2. B. Influenza
3. C. Diabetes (Correct answer)
4. D. Ringworm

Correct Answer

Option C — Diabetes

Detailed Solution & Explanation

The correct answer is Diabetes.

Key Points

• Tuberculosis, Influenza, and Ringworm are all communicable (infectious) diseases.
• Diabetes is a non-communicable, lifestyle/metabolic disease — it cannot be transmitted from person to person.

Additional Information

• Communicable diseases spread from one host to another through a pathogen — bacteria, viruses, fungi or protozoa. Non-communicable diseases do not.
• Group them by agent: bacterial (tuberculosis, typhoid, cholera), viral (influenza, COVID-19, hepatitis), fungal (ringworm, athlete's foot), protozoan (malaria, amoebiasis).
• The main non-communicable diseases are diabetes, hypertension, cancer, cardiovascular disease and asthma — driven by genetics, diet and lifestyle rather than infection.
• Non-communicable diseases now account for the majority of deaths in India, which is why they dominate current public-health policy.
