Question

Which of the following is a communicable disease?

• A. Diabetes
• B. Measles
• C. Cancer
• D. Blood Pressure

Hint:

Communicable diseases = caused by pathogens and can spread between people. Examples: measles, chickenpox, COVID-19, tuberculosis. Non-communicable diseases = not infectious. Examples: diabetes, cancer, hypertension, heart disease.

Answer 1

The Correct Option is B

Step 1: Understanding communicable diseases.
Communicable diseases (also known as infectious or contagious diseases) are illnesses caused by pathogens such as bacteria, viruses, fungi, or parasites that can be transmitted from one person to another or from animals to humans.
Step 2: Characteristics of each disease.

Measles: A highly contagious viral disease caused by the measles virus (paramyxovirus). It spreads through respiratory droplets when an infected person coughs, sneezes, or talks. It is a classic example of a communicable disease.
Diabetes: A metabolic disorder characterized by high blood sugar levels over a prolonged period. It is a non-communicable disease caused by genetic and lifestyle factors, not by pathogens.
Cancer: A group of diseases involving abnormal cell growth with the potential to spread to other parts of the body. Cancer is generally non-communicable and cannot be transmitted from person to person.
Blood Pressure (Hypertension): A condition where the force of blood against artery walls is too high. It is a non-communicable, chronic condition influenced by genetics, diet, and lifestyle.
Step 3: Analysis of each option.

(A) Diabetes: Incorrect. This is a non-communicable metabolic disorder.
(B) Measles: Correct. Measles is a highly contagious viral disease that spreads easily from person to person.
(C) Cancer: Incorrect. Cancer is generally non-communicable, though some viruses (like HPV) can increase cancer risk.
(D) Blood Pressure: Incorrect. Hypertension is a non-communicable chronic condition.
Step 4: Conclusion.
Among the given options, only measles is caused by a pathogen (virus) and can be transmitted from an infected person to a healthy person, making it a communicable disease.
Final Answer: (B) Measles.
