Which of the following diseases is associated with contaminated drinking water?

Typhoid fever is associated with contaminated drinking water because it is caused by the bacterium Salmonella Typhi, which is often transmitted through water contaminated with fecal matter. When individuals consume water or food that has been tainted by this bacterium, they can become infected. The disease is particularly prevalent in areas where water treatment and sanitation practices are inadequate, making access to clean drinking water critical for preventing its spread.

In contrast, influenza is a viral infection primarily transmitted through respiratory droplets rather than water, diabetes is a chronic condition related to insulin and blood sugar levels and is not linked to contaminated water, and asthma is a respiratory condition that is affected by various environmental factors but does not have a direct connection to drinking water contamination.
