Strategies for Improvement

Public health surveillance—and the essential health data that comes from surveillance—are fundamental tools in public health. We use data to know where the health burdens are, to signal anomalies and health risks, and to inform actions and interventions that can keep people safer and healthier. Our understanding of the public’s health is only as good as the data we have, and CDC works around the clock to get the right information into the right hands at the right time.
