About the Author

Andy Wilcox is an independent researcher who has spent more than 30 years applying rigorous analytical methods to complex primary-source material. He is the founder of the Virus Questions network — a group of evidence-based public health information sites covering individual viral diseases.

Andy is not a physician, virologist, or epidemiologist. His background is in analytical research — the discipline of synthesizing large volumes of primary-source material into clear, accurate, and accessible conclusions. He applies that same discipline to public health information, working directly from CDC, WHO, NIH, and peer-reviewed sources rather than secondary summaries.

Methodology

Every clinical page on NorovirusQuestions.com is researched against current CDC and WHO guidance. Pages are reviewed monthly using an automated process that checks each factual claim against the current versions of authoritative sources and applies targeted corrections where the sources have changed. The "Last reviewed" date on each page reflects the most recent automated review.
