Waterborne Diseases

424 WATERBORN ILLNESSES

Waterborne diseases are a major challenge to the world’s population, particularly in developing countries. World Health Organisation (WHO) and UNICEF estimate they are responsible for 80% of all illnesses and a third of all deaths in developing countries[1]. In a separate report, the WHO estimates that 88% of all waterborne illnesses are due to poor hygiene, sanitation and an unsafe water supply[2]

Water is however a fundamental requirement for human life, it makes up 70% of our body. The average person needs to drink about six to eight glasses of water every day.

 

Causes

Waterborne illnesses have two main causes:

  • Chemical hazards and industrial pollution e.g. dangerous levels of chemicals, nitrates or heavy metals in the water supply due to industrial pollution or the over-use of agricultural chemicals.
  • Microbial hazards which invisibly contaminate the water with bacteria, viruses and parasitic organisms that cause disease. Much of this is contamination is through water coming into contact with animal and human waste. Just one gram of faeces can contain up to 100 billion microbes. Much of this contamination is through water coming into contact with animal and human waste.
