Water-related Diseases
Bayani Gaba-gaba
Some of the deadliest diseases in human history travel by water. A child can fall ill from a single mouthful of contaminated water; a village can be devastated by mosquitoes breeding in a nearby pond. Yet these same diseases are among the most preventable on Earth. Clean water, a proper toilet, a bed net and a vaccine can stop an epidemic before it starts.
In this lesson you will learn how two very different water-related diseases spread: cholera, carried in water fouled by human waste, and malaria, carried by a mosquito that breeds in water. You will study the strategies that control each one, from handwashing and chlorination to bed nets and insecticides, and learn to weigh up which works best in a given situation, exactly as the exam asks.
