Public Health Surveillance and Data

Through the Data Modernization Initiative, CDC is creating a world in which data can move faster than disease.

Over the course of the pandemic, CDC has been improving the timeliness, completeness, and quality of critical data for the response.

Progress on modernizing core surveillance systems is helping deliver real-time information through CDC’s COVID Tracker, our “one-stop shop” for COVID-related information.

And, in 2021, CDC stood up a new Center for Forecasting and Outbreak Analytics to forecast and track hotspots for COVID-19 and other emerging biological threats.
