What diseases are related to exposure to contaminated drinking water?

Exposure to contaminated drinking water is directly linked to several infectious diseases, among which typhoid fever and cholera are prominent. These diseases are caused by pathogenic microorganisms that can be found in water sources that are not properly treated or maintained.

Typhoid fever is caused by the bacterium Salmonella enterica serotype Typhi, which is often transmitted through water or food that has been contaminated with feces from an infected person. It manifests with high fever, abdominal pain, and gastrointestinal symptoms, making clean drinking water crucial for prevention.

Cholera is caused by the bacterium Vibrio cholerae and is typically associated with water contaminated by these bacteria, often due to poor sanitation and hygiene practices. The disease leads to severe, watery diarrhea that can lead to dehydration and death if not treated promptly.

The other options do not directly relate to water contamination. Cancers and respiratory infections can have many causes and are not specifically tied to drinking water quality. Ulcers and migraines have various non-infectious triggers, while diabetes and hypertension are chronic diseases influenced by lifestyle and genetics rather than exposure to pathogens in drinking water.

Thus, the diseases most directly associated with contaminated drinking water are indeed typhoid fever and cholera, highlighting the importance of
