Public Health Surveillance and Data

In any crisis, time saved equals lives saved. Accurate, instantaneous data can help us pinpoint diseases from the start and direct resources where they matter most.

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

For example, progress on modernizing core surveillance systems has allowed us to share critical data through CDC’s COVID Tracker, our “one-stop shop” for COVID-related information.
