Frequently Asked Questions

What does Infectious Diseases measure?
Infectious Diseases prevalence is the number of people impacted by infectious diseases in a neighborhood. It combines the impact of all common and emerging pathogens such as influenza, COVID-19, RSV, measles, bird flu, insect-borne illnesses and more into a single score. It gives an idea of how many people are sick in an area at a given time.
How is Infectious Diseases prevalence reported in the Sacramento area?
Infectious Diseases prevalence in the Sacramento area is reported as the weekly score of how many people are impacted in a typical neighborhood in the area, on a five-point scale: Low (<5), Moderate (5–15), High (15–25), Very High (25–40) and Extreme (>40). The score reflects the number of people impacted by Infectious Diseases in a typical neighborhood in the area, validated against public health data from CDC, HHS, EPA, NOAA, and other authoritative sources. Methodology details are available at https://www.hubbubworld.com/intelligence#methodology.
What methodology does Hubbub use to calculate Infectious Diseases prevalence?
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.
