Nationally Notifiable Diseases

Annual Summaries of Notifiable Diseases

The statistical summary of notifiable diseases in the United States is published to accompany each volume of the Morbidity and Mortality Weekly Report by the Centers for Disease Control and Prevention (CDC). This publication contains text, graphs, and maps of the official statistics for the reported occurrence of nationally notifiable diseases in the United States for the designated year. These statistics are collected and compiled from reports to the National Notifiable Diseases Surveillance System (NNDSS), which is operated by CDC in collaboration with the Council of State and Territorial Epidemiologists (CSTE).

The Nationally Notifiable Disease List provides comprehensive reporting of diseases that occur in the United States. The list is compiled through collaborative efforts among state health departments and the Centers for Disease Control and Prevention (CDC). Reporting of diseases is mandated by state legislation and regulations, therefore diseases that are considered notifiable vary from state to state. Internationally notifiable diseases (i.e., cholera, plague, and yellow fever) are also reportable in compliance with the World Health Organization’s International Health Regulations. The following list includes water-related and waterborne diseases that are nationally notifiable.

Cholera (case definition, surveillance data)
Cryptosporidiosis
Cyclosporiasis
Giardiasis
Hepatitis A
Legionellosis
