Water is commonly a source of illness when traveling in foreign countries.
Consumption of water can cause illness from drinking the water, eating fruit and vegetables cleaned with the water, using ice in drinks, while brushing teeth, or taking a shower. Many countries do not have the capability to treat water as we do in the U.S. Bottled water is always a better selection than tap water, and bottled water is available in most countries. Some travelers take purification tablets or boil water during travel. Purification tablets and additional information are available at your local camping supply store. Soda is a great alternative for safe drinking.
