(1) source-0.html.gz (STAT News, 'Measles cases surpass last year's total, hit highest level in 35 years', AP byline, July 24 2026): confirms CDC logged 2,318 cases as of Thursday (July 23) per an agency update Friday (July 24), confirms 2025 total of 2,289 cases described verbatim as 'the worst year for measles in more than three decades', confirms the verbatim quote 'the U.S.'s worst year for measles since 1991', confirms MMR kindergarten coverage 92.5% (2024-25) vs 95.2% (2019-20), confirms South Carolina/Utah/Arizona outbreaks 'sickened hundreds', confirms South Carolina's 997-case outbreak described verbatim as 'the nation's largest outbreak in 35 years', confirms Utah's 700+ cases over more than a year, confirms Dr. Brannon Traxler's exact quote ('impossible to know and may vary during the course of an outbreak') and her title, confirms Dr. Varun Shetty's exact quote and title ('Texas' chief state epidemiologist'), confirms Rémy Pasco's exact quote ('there's just not much you can do about measles once you have it') and affiliation (mathematical epidemiologist, University of Colorado Boulder), confirms the Texas 2025 outbreak estimate 'nearly twice the size of the 762 known cases' verbatim, and confirms the Gaines County detail (182 probable cases unconfirmed, 414 confirmed county total). All STAT-attributed claims and quotes verified verbatim or as faithful paraphrase. (2) source-1.html.gz (Healthline, 'U.S. May Lose Measles Exemption Status As 2026 Cases Surpass Last Year', updated July 22 2026): confirms the Johns Hopkins U.S. Measles Tracker figure of 2,295 cases as of July 21 attributed correctly to Healthline/Johns Hopkins (distinct from the CDC/STAT figure of 2,318 — the two-tracker distinction the article draws is accurate and each figure is attributed to the correct tracker/outlet); confirms 'the South Carolina Department of Public Health declared the outbreak over on April 26, with 997 cases reported in Spartanburg County' verbatim, correctly attributed to Healthline; confirms Utah's Department of Health and Human Services figure of 514 measles cases in 2026 verbatim, correctly attributed to Healthline. ISSUE FOUND: the article presents a direct quotation attributed to Healthline — "The United States is at risk of losing its measles elimination status, which it has held for the past quarter-century" — that does not appear verbatim anywhere in the source. Healthline contains two related but distinct sentences: a summary bullet ('The United States is at risk of losing its measles elimination status, which it has held since 2000.') and a body sentence ('The United States is poised to lose its measles exemption status, which it has held for the past quarter-century.'). The submission's quotation splices the first clause of the bullet with the second clause of the body sentence, producing a quotation that is presented as verbatim but does not match either source sentence exactly. The underlying substance (US elimination status at risk after ~25 years) is accurate and directly supported by the source, but the exact wording in quotation marks is a fabricated composite. This is a single, isolated quote-fidelity issue, not a substantive factual error — the correct information is filed as a correction rather than the article being rejected.
Factual Accuracy: All specific numbers, titles, dates, and paraphrased claims traced correctly to their cited source and tracker, with the one quote-fidelity exception noted above. No hallucinated statistics or invented sources.
Overall Assessment: Substantively strong, well-sourced News piece with accurate lead/summary/headline and correctly cross-attributed dual-tracker figures. One isolated quote-fidelity issue (a spliced quotation attributed to Healthline) is the only defect found after reading both full source snapshots in their entirety; it does not affect the headline, summary, or lead and is honestly correctable via a public corrections note. Verdict: APPROVE_WITH_CORRECTIONS.
