Which one among the following diseases in not caused by polluted water?
Explanation
Waterborne diseases are primarily transmitted through the fecal-oral route via contaminated drinking water or food. Dysentery, typhoid, and jaundice (often caused by Hepatitis A or E) are classic examples of diseases spread through polluted water [6]. Specifically, typhoid is caused by bacterial ingestion, while jaundice results from viral infections like Hepatitis A, which are stable in water and transmitted through sewage contamination [8]. In contrast, Tuberculosis (TB) is primarily an airborne infectious disease caused by Mycobacterium tuberculosis, which spreads through respiratory droplets when an infected person coughs or sneezes. Although some older texts occasionally list tuberculosis alongside waterborne ailments in broad environmental contexts [3], modern medical science and public health standards classify it strictly as an airborne respiratory disease, distinguishing it from the enteric pathogens that characterize water pollution-related illnesses [7].
