This website is provided as a public service by the National Institute of Allergy and Infectious Diseases (NIAID), National Institutes of Health (NIH). NIAID does not disclose, give, sell, or transfer personal information about visitors to http://www.niaid.nih.gov unless required to do so by law. Most information presented on this site is in the public domain and may be distributed or copied with some exceptions.

Protecting your privacy is very important to us. We do not collect personally identifiable information (PII) about you during your visit to the NIAID website unless you choose to give it to us. We do, however, collect some data about visits to our website 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 site. We never collect information for commercial marketing or any purpose unrelated to the NIAID mission and goals. NIAID uses aggregated information only.
How NIAID Collects Information
NIAID automatically collects a limited amount of information about the use of its website, primarily for statistical purposes (that is, to measure the numbers of visitors to various sections of the site). This information also may be helpful when we consider changes to the website to make it more useful to visitors. We make no attempts to identify individual users or their usage habits, except when it may be required for authorized law enforcement investigations.
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 get feedback and data on visitors’ satisfaction with the NIAID website. This survey does not collect personally identifiable information (PII). Participation in the survey is voluntary. If you decline the survey, you still have access to the identical information and resources on the NIAID website as those who do take the survey. Answers to the survey help NIAID improve its website, making easier to use and more responsive to the needs of visitors.
NIAID staff analyzes and reports on the aggregated data from the ACSI survey. The reports are available only to NIAID website managers, members of their teams, and other designated staff who need this information to perform their duties.
The Office of Management and Budget (OMB) Memo M-10-22, Guidance for Online Use of Web Measurement and Customization Technologies, allows federal agencies to use session and persistent cookies.
When you visit any website, 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 to use some features of Web pages. Requests to send cookies from NIAID’s Web pages are designed to collect information about your browser session only; 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.
We use session cookies for technical purposes such as improving navigation through our site. These cookies let our server know that you are continuing a visit to our site. The "session" cookie is not permanently stored on your computer. The cookie and the information about your visit are automatically destroyed shortly after you close your browser to end the session.
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.”
The OMB Memo M-10-22, Guidance for Online Use of Web Measurement and Customization Technologies, allows federal agencies to use persistent cookies in addition to temporary session cookies.
We use persistent cookies to help us differentiate between new and returning visitors to the NIAID website. Persistent cookies remain on your computer between visits to our site until they expire. We do not use this technology to identify you or any other site visitor.
NIAID is running the ACSI survey on its website, which uses "persistent" cookies to block repeated invitations to take the ACSI survey. We also use persistent cookies to enable NIAID to measure and understand how new and returning visitors use our site over time. NIAID uses the following analytic tools: WebTrends, Google Analytics and Crazy Egg.
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.”
If you do not wish to have session or persistent cookies placed on your computer, you can disable them using your Web browser. If you opt out of cookies, you will still have access to all the information and resources on the NIAID website.
Instructions for disabling or opting out of cookies in the most popular browsers are located at http://www.usa.gov/optout_instructions.shtml. Please note that by following the instructions to opt out of cookies, you will disable cookies from all sources, not just those from the NIAID site.
You do not have to give us personal information to visit the NIAID website.
If you choose to give us additional information about yourself through an email message, form, survey, conference registration, etc., we keep the information only as long as needed to respond to your question or to fulfill the stated purpose of the communication.
Voluntarily Submitted Information
NIAID does not disclose, give, sell, or transfer any personal information about our website visitors, unless required for law enforcement or by statute.
The U.S. government maintains the NIAID website. It is protected by various provisions of Title 18, U.S. Code. Violations of Title 18 are subject to criminal prosecution in federal court.
For site security purposes and to ensure that this service remains available to all users, we use software programs to monitor traffic to identify unauthorized attempts to upload or change information or otherwise cause damage. In the event of authorized law enforcement investigations, and pursuant to any required legal process, information from these sources may be used to help identify a person.
Your Visit to NIAID Third-Party Websites
Third-party websites and applications are Web-based technologies that are not exclusively operated or controlled by NIAID. These include applications hosted on non-government sites and those embedded within an NIAID Web page.
As part of the Open Government Directive, we use a variety of new technologies and social media tools to communicate and interact with our audiences. By using some of these applications, your personally identifiable information (PII) can become available or accessible to NIAID, regardless of whether we solicit or collect it. The table below lists the websites and applications we use. If any of these sites or applications collects PII, we describe what is collected and how NIAID protects your information.
On each of the NIAID Facebook pages, NIAID staff post news and other items of interest to users. If you have a Facebook account or “like” NIAID Facebook pages, you can post comments or click on the “like” option for individual entries. If you comment or click on the “like” button, personally identifying information will be visible to NIAID staff and other Facebook site visitors. The amount of visible personal information will depend on your own Facebook privacy settings. You can avoid displaying any personally identifiable information by not creating an account, not posting comments, and not clicking on the “like” options in Facebook.
To create an account, you must provide some personal information, such as your name, user name, password, and email address. You have the option to provide additional personal information, including a short biography, location, or a picture. Most information you provide for a Twitter account is available to the public, but you can modify how much of your information is visible by changing your privacy settings on the Twitter website.
To be notified when NIAID adds new videos, users with YouTube accounts can subscribe to the NIAID channel. NIAID staff members monitor the number of subscribers and may respond to comments and queries on YouTube, but they do not collect, maintain, disclose, or share any information about people who follow NIAID on YouTube.
