 **Our strategy:**
 1. Procure [real-time, aggregated data streams](https://cmu-delphi.github.io/delphi-epidata/) informative of varied infectious diseases and syndromes, in collaboration with industry partners and public health agencies
-1. Extract signals—many at daily and county-level resolution—from these streams and make them widely available via the [Delphi Epidata platform](https://delphi.cmu.edu/covidcast/) and [API](https://cmu-delphi.github.io/delphi-epidata/); enhance their value with automated revision tracking, revision projection, anomaly detection, trend detection, access control, smoothing, and geographic, temporal and demographic disaggregation

 1. Develop and deploy algorithms for epidemic detection, tracking (nowcasting), and forecasting
 1. Develop and share tools for [signal access](https://cmu-delphi.github.io/epidatr/), [processing](https://cmu-delphi.github.io/epiprocess/), and [forecasting](https://cmu-delphi.github.io/epipredict/)
 1. Work closely with public health agencies to understand and support their needs
