What is the National Notifiable Diseases Surveillance System (NNDSS)?

The National Notifiable Diseases Surveillance System (NNDSS) is a critical component of the United States' public health infrastructure. It is a system managed by the Centers for Disease Control and Prevention (CDC) that facilitates the collection, analysis, and dissemination of data on notifiable diseases. These are diseases that, by law, must be reported to government authorities. This system helps in monitoring the occurrence and spread of diseases and is vital for epidemiological research and public health response.
