How does water borne disease harm the body?

Waterborne diseases are illnesses caused by drinking or swimming in water contaminated with harmful bacteria, viruses, or parasites. Waterborne diseases can have a variety of negative effects on the body, including:

* Gastroenteritis: Gastroenteritis is inflammation of the stomach and intestines, and can be caused by a variety of waterborne pathogens such as bacteria (including _E. coli_, _Salmonella_, and Campylobacter), viruses (including norovirus and rotavirus), and parasites (such as _Giardia lamblia_). Symptoms of gastroenteritis can include diarrhea, vomiting, abdominal pain, nausea, and fever.

* Dehydration: Diarrhea and vomiting can lead to dehydration, especially in children and the elderly. Dehydration can cause symptoms such as weakness, dizziness, confusion, and decreased urine output.

* Kidney failure: Some waterborne pathogens, such as Leptospira bacteria, can cause kidney failure. This is a serious condition that can lead to death if not treated promptly.

* Liver damage: Waterborne viruses, such as hepatitis A and E, can cause liver damage. This can range from mild inflammation to severe liver failure.

* Neurological damage: Some waterborne parasites, such as _Naegleria fowleri_, can cause brain damage if they enter the body through the nose. This can lead to a range of symptoms, including fever, headache, nausea, vomiting, and seizures.

* Death: Waterborne diseases can be fatal, especially in developing countries where access to clean water and sanitation is limited.

It is important to note that there are many different types of waterborne diseases, and the symptoms can vary depending on the pathogen involved. Waterborne diseases can be prevented by drinking only clean water, practicing good hygiene, and avoiding contact with contaminated water.
