Advertising disclosure

Public Health Trace uses Google AdSense to serve advertising through manually selected ad placements -- specific, deliberately chosen positions on the homepage, on listing pages, and on record detail pages. Google's Auto Ads feature, which can place ads automatically throughout a page, is not used. Any ad Google serves is always labeled "Ad" or "Advertisement" so it's never mistaken for Public Health Trace's own recall, outbreak, or surveillance content.

Google AdSense uses cookies and similar technologies to serve ads, which may include personalized ads based on your prior visits to this or other websites. See Google's how Google uses information from sites that use its services page for details, and Google's Ads Settings to opt out of personalized advertising.

Advertising placement never affects which recalls or outbreaks are shown, how they're described, or any other editorial or data decision -- that data comes directly from official government sources, described in our methodology and editorial policy. If the advertising provider or approach changes, this page will be updated to match.
