Content Update Policy

Last updated: 2026-07-15

How and when articles on this site are reviewed and updated.

Update cadence

Flagship guides (the site's most in-depth articles) are prioritized for periodic review against current public health guidance. Supporting articles are progressively being expanded from general template content into fully researched, page-specific guides; this is an ongoing project rather than a one-time effort.

How to tell what stage an article is at

Fully developed articles include a dated “Updated” note near the top of the page and a sources list near the bottom. Articles that still rely primarily on general template content are being expanded over time; we do not present template content as a personally researched, page-specific guide.
