Water Sanitation Health

What are the health risks related to stagnant water?

Pools of standing or slow-flowing water provide a breeding ground for many insects, including mosquitoes that can transmit diseases. These mosquitoes are known as vectors. Different species of mosquitoes transmit different diseases, and they will also breed in different types of water collections. In the context of the tsunami disaster, the key water-associated vector-borne diseases are malaria and dengue, with possibly and more speculatively Japanese encephalitis in very local conditions.
