Hubbub World pulls data from multiple authoritative sources: the U.S. Centers for Disease Control and Prevention (CDC) for flu, COVID-19, and RSV surveillance; the U.S. Department of Health and Human Services (HHS) for hospital and community health indicators; the National Oceanic and Atmospheric Administration (NOAA) for weather and air quality; and the American Academy of Allergy, Asthma & Immunology (AAAAI) for allergen reporting. Data is collected continuously from these sources and aggregated to the county and state level on a weekly cadence.

Hubbub World fits proprietary models on top of the underlying surveillance, environmental, and weather data to produce comparable risk scores across all U.S. counties. Each of the seven risks is reported on a four-point scale (Low, Moderate, High, Very High) 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.
