Notice to Readers: Updated "N" Indicators for the Year 2010 in National Notifiable Diseases Surveillance System Tables

The 2010 Council of State and Territorial Epidemiologists (CSTE) State Reportable Conditions Assessment (2010 SRCA) has collected data from 55 reporting jurisdictions (50 U.S. states, the District of Columbia, New York City, and three territories [American Samoa, Guam, and Puerto Rico]) to determine which of the nationally notifiable conditions (NNC) were reportable in each reporting jurisdiction in 2010. The 2010 SRCA gathered information regarding whether the condition is 1) explicitly reportable (i.e., listed as a specific disease or as a category of diseases on reportable disease lists), 2) implicitly reportable (i.e., included in a general category of the reportable disease list, such as "rare diseases of public health importance"), or 3) not reportable within each jurisdiction. Only conditions that were explicitly reportable were considered reportable based on the 2010 SRCA methodology.

Results of the 2010 SRCA will be used to indicate whether each NNC is or is not reportable for the specified period and reporting jurisdiction. NNC that are not reportable are noted with an "N" indicator (for "not reportable") in the MMWR Table II weekly update (Provisional cases of selected notifiable diseases, United States) and in the MMWR Summary of Notifiable Diseases---United States, 2010. This notation will allow readers to distinguish whether 1) no cases were reported even though the condition is reportable or 2) no cases were reported because the condition is not reportable.

The 2010 SRCA data collection and validation concluded in April 2011; results will be used to populate the "N" indicators for National Notifiable Diseases Surveillance System (NNDSS) data in the 2011 MMWR tables for the current week and for both the 2010 and 2011 cumulative year columns. The 2011 NNDSS data displayed in the MMWR weekly provisional tables will reflect reporting requirements gathered from the 2010 SRCA until 2011 SRCA official results are available.
