6.7: Notifiable Diseases
The National Notifiable Disease Surveillance System (NDSS) is a division of the CDC and the hub for reporting and tracking data on specific diseases. If a disease or condition is on the Notifiable Diseases list, it must be reported to the NDSS, thus allowing the CDC to conduct ongoing passive surveillance of many diseases and conditions. Individual states may also have an independent list of reportable diseases as well. The National Notifiable Disease list is updated every year. See below for the list as of 2023 (National Notifiable Diseases Surveillance System (NNDSS) 2021):
