  2. Burden of Disease • Question to group • What is the current global burden of disease?

  3. Burden of Disease • Question to group • For every 10 deaths worldwide how many would you classify as communicable disease related, non-communicable disease related and injuries?

  4. Burden of Disease • Out of every 10 deaths worldwide, • 6 are due to non communicable conditions • 3 to communicable, reproductive or nutritional conditions and • 1 to injuries • Source: World Health Statistics 2009, WHO

  5. Environmental Burden • “In children under the age of five, one third of all disease is caused by environmental factors such as unsafe water and air pollution” • “Every year; the lives of four million children under 5 years – mostly in developing countries could be saved by preventing environmental risks such as unsafe water and polluted air” Source: WHO http://www.who.int/features/factfiles/environmental_health/en/index.html

  6. Environmental Burden of Disease • Question to group • Of the Environmental/WASH related diseases which diseases account for the greatest burden?

  9. The Burden of Disease • Burden of disease: the headlines • 1.9 million attributable annual deaths from diarrhoea • 1.2 million malaria deaths each year • Burden of disease: the details • 1.4 million preventable child deaths from diarrhoea • 860 000 preventable child deaths from malnutrition • One third of the world population (2 billion infections) affected by intestinal parasitic worms • 25 million people seriously incapacitated by lymphatic filariasis • 200 million people with preventable schistosomiasis infections • 5 million people visually impaired by trachoma • 280 000 preventable deaths from drowning Source: Adapted from WHO

  10. Under 5’s • In the under 5’s what are the key causes of death?

  11. New evidence showing that HWWS can reduce ARI’s by up to 23% 35% attributable to malnutrition New evidence showing that maternal HWWS can reduce neonatal mortality by 44% Clear association between undernutrition and intestinal infections Source:Therese Dooley, UNICEF, World Water Day Conference, Dublin, March 09
