Hubbub develops proprietary models on top of geographic, demographic, environmental, surveillance and weather data to produce prevalence scores across the U.S. Prevalence is reported on a five-point scale (Low, Moderate, High, Very High, Extreme) so the scores are interpretable without needing the raw underlying numbers. The full methodology — including the modeling approach, validation against authoritative sources, and known limitations — is documented at https://www.hubbubworld.com/intelligence#methodology. The health risk data on the Hubbub website is for informational purposes only and does not constitute medical advice. Always consult a healthcare professional for personal health decisions.
