Correct Option
The correct option isChicken pox
Explanation
Diseases are broadly classified into two categories based on their mode of transmission: communicable (infectious) and non-communicable (non-infectious). Communicable diseases are caused by pathogens such as bacteria, viruses, fungi, or parasites and can spread from an infected individual to a healthy individual through direct contact, vectors, or contaminated mediums (air, water, food). Non-communicable diseases are not transmissible and typically result from genetic, physiological, environmental, or behavioral factors.
Option Analysis
- Diabetes: Incorrect. Diabetes is a chronic metabolic disorder affecting how the body processes blood sugar. It is a non-communicable disease often linked to genetic factors and lifestyle choices.
- Chicken pox Chicken pox: Correct. Chicken pox is a highly contagious disease caused by the Varicella-zoster virus. It is classified as a communicable disease because it spreads easily through direct contact with the rash or through respiratory droplets (coughing or sneezing).
- Cancer: Incorrect. Cancer involves the uncontrolled division of abnormal cells in a part of the body. It is a non-communicable disease and cannot be transmitted from person to person.
- Hypertension: Incorrect. Hypertension (high blood pressure) is a chronic condition related to cardiovascular health, genetics, and lifestyle. It is non-communicable.
Key Takeaway: Communicable diseases (e.g., Chicken pox, Tuberculosis, Influenza) are infectious and transmissible via pathogens, whereas non-communicable diseases (e.g., Diabetes, Cancer, Hypertension) are chronic and non-transmissible.
