The question asks to identify which disease among the options is typically not caused by water pollution. Let's examine the common causes and transmission routes for each disease listed.

Water Pollution Disease Analysis

Water pollution can lead to various infectious diseases when contaminated water is consumed or used for hygiene. Common waterborne pathogens include bacteria like Vibrio cholerae and Salmonella Typhi, as well as viruses and parasites causing diarrhoea.

• Cholera: Primarily caused by Vibrio cholerae bacteria, often spread through contaminated water and food.
• Typhoid: Caused by Salmonella Typhi bacteria, typically spread through contaminated water or food.
• Diarrhoea: A symptom that can result from infections by various pathogens (bacteria, viruses, parasites) often transmitted via contaminated water.
• Plague: This disease is caused by the bacterium Yersinia pestis. Its primary transmission route is through the bite of infected fleas, which usually affects rodents. It is not considered a waterborne disease.

Based on the typical modes of transmission, Plague is the disease that is not caused by water pollution.
