Don’t drink the water- how to avoid water related disease

You’ve probably heard the advice “Don’t drink the water” when you travel to less developed areas of the world. But water can make you sick even without drinking it.

Bacteria and other disease causing organisms can be transmitted by swimming and other water related sports

• in private and public pools
• recreational freshwater and oceans
• hot tubs, splash pads, water parks
• decorative fountains

Drinking, inhaling, and direct contact with water contaminated with a variety of bugs can cause a wide range of illness, most of which is preventable. Here is an overview of common conditions to watch out for.

Drowning-

The most serious risk of water is drowning or near drowning, with 3,300 deaths and another 5,000 hospitalizations annually in the United States.

Children are especially at risk of drowning. Teaching children to swim as early as practical and supervising them around pools and other bodies of water are critical to prevention.
