Evidence-based answers to your most important norovirus questions
Corrections Policy
NorovirusQuestions.com is committed to accuracy. All clinical content is reviewed monthly against current CDC and WHO guidance using an automated review process. Despite these measures, errors may occur. This page describes how we handle them.
How to Report an Error
If you believe a page on this site contains a factual error — a claim that contradicts current CDC, WHO, NIH, or peer-reviewed evidence — please contact us at andywilcox001@gmail.com with:
The URL of the page with the error
The specific claim you believe is inaccurate
A link to the authoritative source that contradicts it (CDC, WHO, NIH, or peer-reviewed journal)
How We Handle Corrections
We review all reported errors against the cited source. If the source clearly contradicts the claim, we correct the page within 5 business days and update the dateModified and lastReviewed schema fields to reflect the correction date. If the error is significant, we may note the correction at the bottom of the affected page.
We do not correct pages based on opinion, interpretation differences, or sources that are not authoritative (e.g., news articles, blog posts, anecdotal reports). Our corrections are grounded in CDC, WHO, NIH, or peer-reviewed primary sources.
Automated Monthly Review
In addition to reader-submitted corrections, all clinical pages are automatically reviewed on the 1st of each month against current CDC and WHO source content. This automated process identifies outdated statistics, changed guidelines, and new clinical recommendations. The "Last reviewed" date on each page reflects the most recent review, whether automated or manual.
What We Do Not Correct
We do not correct pages based on opinion, interpretation differences, or sources that are not authoritative — such as news articles, blog posts, or anecdotal reports. Our corrections are grounded in CDC, WHO, NIH, or peer-reviewed primary sources. If the authoritative guidance itself is evolving or contradictory, we will note that uncertainty on the page rather than picking a side.
Correction Log
When significant factual corrections are made, they are noted on the affected page with a correction date. This transparency is a core part of how we maintain reader trust over time. Minor corrections — fixing typos, broken links, or formatting — are applied without annotation. Material corrections that change a stated fact are always noted.
If you submitted a correction and would like to know the outcome, include your email address in your submission and we will follow up.
The record: every correction made to this site
5 entries are logged for NorovirusQuestions.com, plus 1 applied across the whole network — each traceable
to the change that made it.
That includes 1 reported error that was investigated and found not to be one — logged rather than quietly dropped. The least flattering entries are the point of publishing this.
Corrected
Outbreak-setting percentages (3 pages)
What was published: The transmission, outbreaks, and cruise-ship pages attributed specific outbreak shares to CDC — "~65%" for long-term care facilities, "~15–20%" for restaurants, and "~10%" for schools.
What it says now: CDC’s Norovirus Outbreaks page says "over half of all norovirus outbreaks reported in the United States occur in long-term care facilities" and publishes no percentage for restaurants or schools; it does state that norovirus causes about 50% of foodborne-illness outbreaks and that cruise ships are about 1% of reported outbreaks. The three pages now carry CDC’s actual wording and figures.
What was published: The FAQ named Takeda’s TAK-214 as among the most advanced norovirus vaccine candidates.
What it says now: Out of date. The most advanced candidate on the public record as of September 2026 is Moderna’s mRNA-1403, in a Phase 3 trial of 37,864 adults (ClinicalTrials.gov NCT06592794, primary completion estimated February 2027). No norovirus vaccine is approved.
What was published: Four citation-level errors found in the September 2026 depth review: the symptoms page cited an unverifiable review via a PubMed search URL; the outbreaks page gave the wrong PubMed ID (26978248) for Bartsch et al. 2016; the homepage attributed the 685 million global illness figure to WHO; the treatment page attributed a "no BRAT diet" recommendation to CDC guidance, which addresses fluids rather than diet.
What it says now: The symptoms reference was replaced with the specific studies cited in the text (Atmar 2008, Atmar 2014, Burke 2021); Bartsch 2016 is PubMed 27115736; the 685 million figure is attributed to CDC’s Facts and Stats page, which states it; the diet paragraph now cites WHO’s diarrhoeal-disease guidance ("nutrient-rich foods") and says plainly that CDC’s norovirus page does not address diet.
Reported error rejected
Heat inactivation temperature
What was published: An internal audit flagged the stated 145°F cooking temperature as a self-contradiction against other guidance on the site.
What it says now: No change. On review, CDC’s Norovirus Fact Sheet for Food Workers supports the figure as published. The flag was a false positive and was recorded as one rather than quietly dropped.
Source: CDC — Norovirus Fact Sheet for Food Workers
Corrected
CDC programme name
What was published: CDC’s cruise-ship inspection programme was referred to as the "VESSEL program."
What it says now: Vessel Sanitation Program (VSP). Seasonality was also corrected to November–April.
What was published: Stored news items reproduced verbatim summary text from New York Times and BBC articles.
What it says now: All 42 stored summaries were removed retroactively across the news and archive sections of every spoke, and a headline-only policy adopted for those publishers going forward.
Entries begin in July 2026, when the network moved to a single repository and changes became
individually traceable. Earlier corrections were not logged in a citable form and are not
reconstructed from memory. The full network-wide log, including corrections on the other
sites, is on VirusQuestions.com.
