Outbreak Radar API
Real-time CDC wastewater surveillance data for developers and researchers
What the API Provides
The Outbreak Radar API exposes normalized CDC NWSS wastewater surveillance data across 700+ US monitoring sites. Every data point is PMMoV-normalized and scored against that site's own historical baseline — giving you comparable, cross-site percentile scores rather than raw concentration values.
- Real-time viral activity levels for COVID-19, Flu A, RSV, and Measles
- Per-site percentile scores (0–100) relative to each site's history
- Geographic data: county, state, coordinates for every monitoring site
- Weekly time-series data going back to 2022
- Updated weekly as CDC publishes new NWSS data
Use Cases
- Travel health apps — show disease activity at the destination before users book
- Corporate wellness platforms — alert HR teams when illness is rising near offices
- Insurance and risk assessment — incorporate wastewater signals into actuarial models
- Academic research — access cleaned, normalized wastewater data for epidemiological studies
- News and media — power live data visualizations for health reporting
- Public health dashboards — embed regional illness data into existing monitoring tools
