This page explains what cookies are, the types of cookies a website like this one typically uses, and how you can control them. It is written in plain language.
What cookies are
Cookies are small text files that a website asks your browser to store on your computer, tablet, or phone. They help websites work properly and remember simple choices.
Cookies are widely used. A cookie is not a program, and it cannot carry viruses. Most cookies do not identify you by name. Some hold a random code so the website can tell one visit from another.
When you return to a website, your browser sends the relevant cookies back, so the website can, for example, remember that you have already seen a message or chosen a setting.
Types of cookies this kind of website typically uses
Essential cookies. These are needed for the website to work and stay secure. They help with basic functions such as loading pages, protecting forms from misuse, and remembering privacy choices. The website cannot work properly without them, so they do not need extra agreement.
Analytics cookies, if enabled. These help the website owner understand, in general terms, how many people visit, which pages are read most, and how visitors move through the site. This information is grouped together and is used to improve the content. It is not used to build a detailed profile of you. Analytics cookies are only used where they have been turned on for the site.
Embedded content cookies. Some pages may include content hosted elsewhere, such as a video or a map. If you view or play that content, the other service may set its own cookies. This website only links out to trusted, authoritative health sources, but any embedded content is provided by the service that hosts it, and its own cookie rules will apply.
This website does not use cookies to sell your information, and it does not aim to track you across other websites for advertising.
Our approach to consent
Only essential cookies are used unless you agree to more, where a cookie consent tool is shown on this website.
If a consent tool appears, you can accept or reject non-essential cookies there. You can also change your mind later by clearing cookies in your browser and visiting the site again, or by using the consent tool if it is shown again.
How to control cookies in your browser
You are in control. You can view, block, or delete cookies at any time in your browser settings. The exact steps differ slightly between browsers, but in general:
- Open your browser and go to its settings or preferences menu.
- Look for a section called “Privacy”, “Privacy and security”, or “Cookies”.
- From there, you can see which cookies are stored, delete some or all of them, and choose to block cookies from some or all websites.
- Close and reopen your browser if the browser asks you to, so the new settings take effect.
Most browsers also let you browse in a private or “incognito” window, which deletes cookies when you close the window.
Please note: if you block all cookies, some parts of this and many other websites may not work as expected, because essential cookies are needed for basic functions.
For more detail, use the “Help” section of your own browser, which gives steps for your exact version.
Changes to this policy
