We report a discrepancy between the number of patients with scarlet fever diagnoses in hospitals and the numbers reported in the NNID system.
Incidence of scarlet fever determined using NNID and HIRA data, South Korea, 2011-2016.
Patients with NNIDs fall into the following 3 categories: confirmed case-patient, a person with compatible clinical symptoms who was positive for a group A Streptococcus by laboratory tests; suspected case-patient, a person with compatible clinical symptoms who was not tested or not positive for the pathogen by laboratory tests; and pathogen carrier.
In addition, a CSTE-CDC initiative is implementing a methodologic change in the way CSTE and CDC solicit and document reporting requirements for nationally notifiable infectious diseases (NNIDs).
As of January 5, 2008, two condition categories have been revised in the list of NNIDs: ehrlichiosis and Q fever.
