Naturally found in fresh water, the Legionella family of bacteria can cause legionellosis, which is a type of pneumonia. Cough, shortness of breath, high fever, muscle pains, and headaches are common signs of legionellosis. Like many water-borne diseases, it can also result in nausea, vomiting, and diarrhoea.
Pontiac fever is a less severe form of legionellosis, which resolves on its own.
Considered a neglected disease by the World Health Organization, giardiasis or beaver fever is a parasitic disease caused by Giardia lamblia. Diarrhoea, abdominal pain and weight loss are common, but few people also experience vomiting, blood in the stool and fever.
There are different varieties of E.Coli bacteria, most of which are harmless. But this particular strain of the bacteria can result in patients suffering from kidney failure in addition to other usual symptoms such as bloody diarrhoea, abdominal pain, nausea, vomiting and fever.
This is an infectious disease caused by Chlamydia trachomatis bacterium. Also known as blinding trachoma, the infection makes the inner surface of the eyelids rough. This leads to pain and can damage the eyes’ cornea, eventually leading to blindness.
Heavy metal poisoning
Cadmium, mercury, lead and arsenic are heavy metals that are the leading cause of poisoning through water contamination. Unregulated release of chemicals containing these metals by industries is a major cause for concern. Heavy metals make their way into water bodies, and when ingested, they lead to a whole range of illnesses. The accumulation of heavy metals in our bodies (called bioaccumulation) usually leads to life threatening health disorders.
