Travelers’ Health

The CDC provides a comprehensive guide for travelers, including information on destinations, vaccinations, diseases, injury and illness abroad, and many other important safety topics.

No one wants to think about getting sick or hurt during a trip, but sometimes these things happen. You may not be able to prevent every illness or injury, but you can plan ahead to be able to deal with them.

If you will be traveling soon, be sure to visit CDC's Travelers’ Health site, or check out the links below.

Sanitation

In addition to using safe drinking and recreational water, it is important to also protect yourself and others from waterborne illness by paying attention to good sanitation practices:

• Disposing of human waste appropriately. When possible, use permanent sanitation facilities (toilets and latrines). If these facilities are not available, dispose of human waste by burying it at least 8 inches deep and at least 200 feet from natural waters.
• Practicing good personal hygiene. If possible, wash hands with soap and clean, running water before handling food or eating, and after using the toilet.
