To protect Americans from serious disease, the National Notifiable Diseases Surveillance System helps public health monitor, control, and prevent about 120 diseases. These diseases are important to monitor nationwide and include infectious diseases such as Zika virus infections, foodborne outbreaks such as E. coli, and noninfectious conditions such as lead poisoning. About 3,000 public health departments gather and use data on these diseases to protect their local communities. Through NNDSS, CDC receives and uses these data to keep people healthy and defend America from health threats.

As part of the CDC Surveillance Strategy, the NNDSS Modernization Initiative is enhancing the system’s ability to provide more comprehensive, timely, and higher quality data than ever before for public health decision making.
