As a source for health information, the Internet is both a blessing and a curse. The sheer number of Web sources means you can find information on any disease, condition or concern. But assuring the quality and validity of the information is another story.

Our hospital’s Web site is an excellent starting point for online health information searches. The sites of federal health agencies, such as National Institutes of Health and Centers for Disease Control and Prevention, are also good sources.

Major medical institutions, including Cleveland Clinic and Mayo Clinic, also are reliable, as are advocacy organizations such as the American Cancer Society and American Heart Association.

Check that the site you’re using meets health information standards, such as the Health on the Net (HON) Code or the URAC Accredited Health Web site distinction. Qualifying sites display these symbols to show that they meet standards for content, privacy and security. WebMD is one such site.
