How We Research & Review

Who Writes This Site

NorovirusQuestions.com is researched and written by Andy Wilcox, an independent researcher and the founder of the Virus Questions network.

Andy is not a physician, virologist, or epidemiologist. His background is in analytical research — applying rigorous primary-source methodology to complex bodies of evidence. He holds an MBA and professional credentials (CPA, PMP), and has spent 30+ years as a consultant, operating executive, and investor.

He applies that same analytical discipline to public health information: working directly from CDC, WHO, NIH, and peer-reviewed sources rather than from secondary summaries or news articles.

This site is not reviewed by any licensed clinician. No physician or any other healthcare professional reviews content before or after publication. The content represents Andy Wilcox's independent research and synthesis of authoritative primary sources — not medical opinion.

Primary Sources We Use

Every factual claim on clinical pages is sourced to one of the following. We do not cite news articles or other websites as primary evidence for clinical claims. Statistics are cited with their source; where CDC and WHO figures differ, both are noted.

• CDC — U.S. primary authority for norovirus surveillance, outbreak data, and clinical guidance
• WHO — global burden of disease data and international public health guidance
• FDA — food safety guidance related to norovirus in food handling and recalls
• NIH / PubMed — biomedical research database and peer-reviewed literature
• Peer-reviewed journals — Journal of Infectious Diseases, Emerging Infectious Diseases (CDC), Clinical Infectious Diseases, NEJM, The Lancet, JAMA, MMWR, and others

We apply a hierarchy of evidence consistent with evidence-based medicine: systematic reviews and RCTs first, followed by CDC/WHO guidance, then observational data. When sources disagree, we note the disagreement rather than picking a side.

Fact-Checking Process

Every factual claim on a clinical page goes through the following steps before publication:

1. Source identification — The specific CDC page, WHO document, FDA guidance, or peer-reviewed study that supports the claim is located and linked.
2. Claim verification — The claim is compared directly to the source text to confirm accuracy of both substance and nuance. Paraphrasing is checked to ensure it does not change the meaning of what the source says.
3. Cross-reference check — Where possible, significant clinical claims are cross-checked against at least two independent authoritative sources.
4. Uncertainty flagging — Any claim that is provisional, contested, or based on limited data is marked as such in the published text.

Monthly Review Process

Every clinical page undergoes an automated monthly review against current CDC and WHO guidance:

1. Current CDC and WHO source documents are fetched on the first of each month.
2. An automated review compares existing page claims against those authoritative sources.
3. Only claims that are directly contradicted by current authority guidance are flagged — the review does not rewrite or expand content speculatively.
4. Human review of the automated output is performed before any changes are committed.
5. Corrections are applied to affected pages; the "Last reviewed" date is updated on every reviewed page.

The "Last reviewed" date on each page reflects the most recent review cycle. Pages that passed review without changes are still date-stamped to show they were actively checked. Ad hoc corrections for errors identified at any time are applied promptly, independently of the regular review schedule.

Independence and Funding

NorovirusQuestions.com is independently operated. It has no financial relationship with any pharmaceutical company, public health agency, or healthcare institution. Content is not influenced by any organization with a financial interest in the subject matter.

This site generates revenue through two disclosed mechanisms:

• Google AdSense — display advertising served by Google. Ad content is determined by Google's algorithms and is not selected or endorsed by this site. Advertising has no influence over editorial content.
• Amazon Associates — affiliate links to relevant products, disclosed on every page where they appear. Product recommendations are based on clinical relevance and alignment with CDC guidance — not commission rates or affiliate relationships.

Neither revenue source influences which topics are covered, how they are framed, or what the factual content says.
