Water-related diseases are caused by a variety of pathogens, including bacteria, viruses, and parasites, that can be found in contaminated water. These pathogens can cause a range of illnesses, including diarrhea, cholera, typhoid fever, and hepatitis A.

The most common cause of water-related diseases is the consumption of contaminated water. Contamination can occur due to a variety of factors, including inadequate sanitation, poor hygiene, and pollution from human and animal waste.

Water-related diseases disproportionately affect vulnerable populations, including children under the age of five, pregnant women, and people living in poverty. Improving access to safe drinking water and sanitation is an important step in reducing the burden of water-related diseases.
