Question

Which among the following disease is not transmitted through air?

• A. Tuberculosis
• B. Measles
• C. Typhoid
• D. Monkey pox

Hint:

Categorize common diseases by their primary mode of transmission:

\textbf{Airborne:} Tuberculosis, Influenza, Measles, Chickenpox, COVID-19.
\textbf{Water-borne:} Cholera, Typhoid, Dysentery, Hepatitis A.
\textbf{Vector-borne (e.g., mosquitoes):} Malaria, Dengue, Zika.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept
The question asks to identify the disease from the list that is not airborne (i.e., not transmitted by inhaling droplets or aerosols containing the pathogen).

Step 2: Analyzing the Modes of Transmission


(A) Tuberculosis: This is a classic airborne disease caused by the bacterium \textit{Mycobacterium tuberculosis}, which spreads through respiratory droplets when an infected person coughs or sneezes.

(B) Measles: This is a highly contagious viral disease that spreads through the air by respiratory droplets produced from coughing or sneezing.

(C) Typhoid: Typhoid fever is a bacterial infection caused by \textit{Salmonella Typhi}. It is transmitted through the fecal-oral route, typically by consuming contaminated food or water. It is a water-borne disease, not an airborne one.

(D) Monkeypox: According to health organizations, Monkeypox can be transmitted through close contact with respiratory secretions, skin lesions of an infected person, or recently contaminated objects. Prolonged face-to-face contact can lead to transmission through respiratory droplets, so it has an airborne component, although close contact is the primary mode.


Step 3: Final Answer
Tuberculosis, Measles, and to some extent Monkeypox can be transmitted through the air. Typhoid is transmitted through contaminated food and water. Therefore, Typhoid is not an airborne disease. Option (C) is the correct answer.
