 About Cookies

A cookie is a small piece of information that a Web site stores in the Web browser. The cookie might reside in memory, or it might be placed in a special folder on the hard drive so it can be retrieved by the Web site later. Only the Web site that sets the cookie can read it.

This site does not collect personal information that could be used to identify you or your activities, unless you have knowingly submitted specific information by completing a form, nor does it use cookies to track visits. The cookies we use fall into two categories.

  1. Cookies that reside only in the temporary memory of your computer and not on the hard drive. This type of cookie is used to move information between pages in an interactive site. Any such cookie will only last through a single session or visit. When you close your browser, the cookies will be automatically deleted.
  2. Cookies that reside on the hard drive and that contain no personal information. Any cookie of this type will only be used to enhance your experience of the site. For example, a training module may remind you of sections that you have completed. The cookie information will not be used or collected by CDC and will not contain any personal or sensitive information that can be collected by any other means.

Unless otherwise indicated, our use of cookies is limited to temporary cookies. If your Web browser is configured to refuse cookies, some features may not work properly.
