The water-borne diseases are so named because they are caused by drinking or contact with dirty water.
This non-potable water carries micro-organisms (bacteria, eukaryotes, etc.), viruses, and chemical contaminants (lead, pesticides, etc.) which cause potentially fatal problems and diseases.
Cholera, dysentery, typhoid, fever, poliomyelitis, hepatitis A and E are amongst the most frequent water-borne diseases.
Hygiene education, development of waste processing systems and water sanitisation will help to limit epidemics of these diseases in the long term.
Lack of sanitisation systems leads to pollution of water drunk by populations and the development of water-borne diseases. © Christine Werner / Sustainable Sanitation CC by-nc-nd 2.0
