Accessibility statement

Public Health Trace is built to be usable by everyone, including people using assistive technology. We aim to meet the Web Content Accessibility Guidelines (WCAG) 2.2 at Level AA.

What we've built in

• A single, meaningful heading hierarchy on every page, so screen reader users can navigate by heading.
• Visible keyboard focus indicators on every interactive element, including links, buttons, and form fields.
• Forms (alert subscription, alert management, and contact) that work fully via keyboard and without JavaScript, since they submit as plain page forms.
• Descriptive link text and alt text on meaningful images, rather than generic "click here" links or unlabeled icons.
• Sufficient color contrast between text and background across both light and dark themes.
• Skip-to-content and landmark regions (header, main, footer) so navigation doesn't require reading every page top to bottom.

Known limitations

Accessibility is an ongoing effort, not a one-time checklist. If you encounter a page, control, or piece of content that isn't accessible to you, we want to know so we can fix it.

Reporting an accessibility issue

Use our contact form (choose the "Technical issue" category) and let us know the page, what assistive technology or browser you were using, and what happened. We'll do our best to respond and address confirmed issues promptly.
