Data is updated daily. The composite score uses a weighted average of individual disease risk scores.

Frequently Asked Questions
What is Infectious Diseases Risk?
Infectious Diseases Risk is a combined indicator that captures the overall burden of respiratory infectious disease in an area. It incorporates flu, COVID-19, RSV, and other circulating respiratory pathogens into a single score, useful when you want a general respiratory illness risk reading rather than a per-pathogen breakdown.
How is Infectious Diseases risk measured in King County?
Infectious Diseases risk in King County is reported as a weekly score on a four-point scale: Low, Moderate, High, and Very High. The score reflects the modeled burden of Infectious Diseases at the county level, validated against public health data from CDC, HHS, NOAA, and other authoritative sources. Methodology details are available at https://www.hubbubworld.com/intelligence#methodology.
What methodology does Hubbub World use?
Hubbub World develops 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.
