Top 5 Waterborne Disease

Waterborne diseases are caused by consuming water that has been contaminated by disease-causing microbes or pathogens. Many waterborne pathogens also make way to the human body through food or beverages, contact with animals or their environment, or through person-to-person.

According to World Health Organisation, such diseases account for an expected 4.1% of the total Disability-Adjusted Life Year (DALY) global burden of disease and cause around 1.8 million human deaths annually. The World Health Organisation evaluates that 88% of that burden owes to the unsafe water supply, sanitation and hygiene.
