Diseases associated with poor access to clean water.

Diseases associated with poor access to clean water.

• A. Hepatitis A
• B. Malaria
• C. Tuberculosis
• D. Dysentery, Typhoid, Cholera

Answer: (D)

When clean water is hard to come by, infections spread primarily through contaminated water and poor sanitation. Dysentery, typhoid, and cholera are classic waterborne diseases tied directly to that exposure: dysentery causes painful diarrhea often with blood from intestinal infection; typhoid fever is a systemic illness acquired by ingesting contaminated water or food; cholera causes severe, watery diarrhea that can rapidly lead to dehydration. These conditions rise in places with unsafe drinking water and inadequate sanitation, making them the most characteristic group for this scenario. Malaria is mosquito-borne, TB is airborne, and hepatitis A, while also fecal-oral in some cases, is not as strongly linked to water access as the trio above.
