Privacy Policy

General Information

This Web site is provided as a public service by the National Institute of Allergy and Infectious Diseases (NIAID), National Institutes of Health. NIAID does not disclose, give, sell, or transfer any personal information about visitors to http://www.niaid.nih.gov/ unless required to do so by law. Information presented on this Web site is considered public information and may be distributed or copied with some exceptions. For more information on image and text reuse, see Copyright and Reuse of Graphics and Text.

Protecting your privacy is very important to us. We do not collect any personally identifiable information (PII) about you during your visit to NIAID Web sites unless you choose to provide it to us. We do, however, collect some data about your visit to our Web site to help us better understand how the public uses the site and how to make it more helpful. We collect information from visitors who read, browse, and/or download information from our Web site. NIAID never collects information for commercial marketing or any purpose unrelated to the NIAID mission and goals.

Site Management

NIAID automatically collects a limited amount of information about the use of its Web site, primarily for statistical purposes (that is, to measure the numbers of visitors to various sections of the site). This information may also be helpful when considering changes to the web site to make the site more useful to visitors. Except where it may be required for authorized law enforcement investigations, no other attempts will be made to identify individual users or their usage habits.

Types of Information Collected

When you browse through any Web site, certain information about your visit can be collected. We automatically collect and temporarily store the following type of information about your visit:

  • Domain from which you access the Internet
  • IP address (an IP address is a number that is automatically assigned to a computer when surfing the Web)
  • Operating system and information about the browser used when visiting the site
  • Date and time of your visit
  • Pages you visited
  • Address of the Web site that connected you to an NIAID Web site (such as google.com or bing.com)

We use this information to measure the number of visitors to our site and its various sections and to help make our site more useful to visitors.

How NIAID Collects Information

NIAID Web sites use a variety of different Web measurement software tools and specific information regarding information collection can be found on their respective Web sites.

NIAID uses Webtrends measurement software to collect the information in the bulleted list in the Types of Information Collected section above. Webtrends collects information automatically and continuously. No personally identifiable information is collected. NIAID staff conducts analyses and reports on the aggregated data from Webtrends. The reports are only available to NIAID managers, members of the NIAID Communications and Web Teams, and other designated staff who require this information to perform their duties.

NIAID also uses online surveys to collect opinions and feedback from a random sample of visitors. NIAID uses the ForeSee Results’ American Customer Satisfaction Index (ACSI) online survey to obtain feedback and data on visitors’ satisfaction with the NIAID Web site. This survey does not collect personally identifiable information. Although the survey invitation pops up for a random sample of visitors, it is optional. If you decline the survey, you will still have access to the identical information and resources at the NIAID site as those who do not take the survey. The survey reports are available only to NIAID managers, members of the NIAID Communications and Web Teams, and other designated staff who require this information to perform their duties.

NIAID retains the data from Webtrends and ACSI survey results as long as needed to support the mission of the NIAID Web site.

How NIAID Uses Cookies

The Office of Management and Budget Memo M-10-22, Guidance for Online Use of Web Measurement and Customization Technologies (PDF) allows Federal agencies to use session and persistent cookies.

When you visit any Web site, its server may generate a piece of text known as a "cookie" to place on your computer. The cookie allows the server to "remember" specific information about your visit while you are connected. The cookie makes it easier for you to use the dynamic features of Web pages. Cookies from NIAID Web pages only collect information about your browser’s visit to the site; they do not collect personal information about you.

There are two types of cookies, single session (temporary) and multi-session (persistent). Session cookies last only as long as your Web browser is open. Once you close your browser, the cookie disappears. Persistent cookies are stored on your computer for longer periods.

Session Cookies: We use session cookies for technical purposes such as to enable better navigation through our site. These cookies let our server know that you are continuing a visit to our site. The OMB Memo 10-22 Guidance defines our use of session cookies as “Usage Tier 1—Single Session.” The policy says, “This tier encompasses any use of single session web measurement and customization technologies.”

Persistent Cookies: We use persistent cookies to enable Webtrends to differentiate between new and returning NIAID visitors. Persistent cookies remain on your computer between visits to NIAID Web site until they expire. We also use persistent cookies to block repeated invitations to take the ACSI survey. The persistent cookies that block repeated survey invitations expire in 90 days. The OMB Memo 10-22 Guidance defines our use of persistent cookies as “Usage Tier 2 – Multi-session without Personally Identifiable Information (PII).” The policy says, “This tier encompasses any use of multi-session Web measurement and customization technologies when no PII is collected.”
