Infectious Disease Information

Water-Related Diseases

In the United States, the drinking water supply is normally safe. Yet diseases that spread through water are still a very real problem. When there’s a water main break or other interruption, or in areas where clean water is unavailable, what should you do?  When you camp or travel, how do you lower your risk of getting sick from waterborne germs? How about avoiding diseases that can be spread when you and your family swim or play in lakes, streams, pools, or waterparks?

To find information on other health topics that concern water, such as water safety, see the CDC Health Topics A-Z index.

NOTE: CDC is not a hospital or clinical facility; we do not see patients and are unable to diagnose your illness, provide treatment, prescribe medication, or refer you to specialists.

If you have a medical emergency, contacting CDC is not the proper way to get immediate help. Instead, please contact your health care provider or go to the nearest emergency room. If you are a health care provider, please contact your state epidemiologist or local health department.
