Step 1: Concept Definition:
Water-borne diseases are illnesses caused by microorganisms transmitted via contaminated water. The objective is to identify the disease not spread through this route.
Step 3: Detailed Analysis:
\[\begin{array}{rl} \bullet & \text{(A) Cholera: A common water-borne disease caused by Vibrio cholerae, transmitted through contaminated food and water.} \\ \bullet & \text{(B) Giardiasis: A diarrheal illness caused by the parasite Giardia lamblia, frequently spread via contaminated water.} \\ \bullet & \text{(C) Bronchitis: An inflammation of the bronchial tubes, typically caused by viral or bacterial respiratory infections, or irritants such as smoke and air pollution. This is an airborne/respiratory illness, not water-borne.} \\ \bullet & \text{(D) Dracontiasis (Guinea-worm disease): A parasitic disease caused by the Guinea worm, transmitted by drinking water containing copepods (water fleas) that have ingested the worm's larvae.} \\ \end{array}\]
Step 4: Conclusion:
Bronchitis is classified as a respiratory condition, not a water-borne disease.
