Infectious diseases with an important environmental contribution in developing countries.

Infectious diseases of poverty	Burden of disease attributable to environmental causes	Environmental risks
Diarrhoeal diseases	94% of the 1.8 million annual deaths	Unsafe drinking water and inadequate sanitation
Lower respiratory infections (LRI)	1.5 million deaths annually (41% of the LRI disease burden)	Exposure to indoor smoke from solid fuels and outdoor (ambient) air pollution
Vector-borne disease	Over 500,000 deaths annually	Modifiable environmental factors (such as poorly designed irrigation and water systems; poor housing and settlement; deforestation and ecosystem change/degradation)
