title: Notice to Readers: NNDSS Tables Have Updated "N" Indicators for 2015 and 2016.
abstract: CDC's National Notifiable Diseases Surveillance System (NNDSS) maintains and annually updates information about whether each Nationally Notifiable Infectious Condition (NNIC) is considered "reportable" (by health care providers, hospitals, laboratories, or other public health reporters) in each reporting jurisdiction. NNDSS personnel within the Division of Health Informatics and Surveillance performed assessments with each reporting jurisdiction to ascertain the reportable disease status of each NNIC for 2015 and 2016. NNICs that are not designated reportable are indicated with an "N"; NNICs that are reportable, but for which no cases were reported, are indicated with a "-" and NNICs that are reportable, but for which data are not available in a jurisdiction, are designated by either "U" or "NA." These designations are used in the annual MMWR Summary of Notifiable Diseases - United States and in the weekly MMWR Notifiable Diseases and Mortality Tables I and II of provisional NNDSS data.
