IID-3 Reduce meningococcal disease

About the Data

Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.

Data Source: 
National Notifiable Diseases Surveillance System
Changed Since the Healthy People 2020 Launch: 
Baseline (Year): 
1,215 (2004–08)
Target-Setting Method: 
10 percent improvement

Number of new laboratory-confirmed meningococcal disease cases reported in past 12 months

Comparable Healthy People 2010 Objective: 
Adapted from HP2010 objective
Data Collection Frequency: 
Methodology Notes: 

    Estimates represent the mean number of Confirmed, Probable, and Unknown cases of meningococcal disease reported to NNDSS during the relevant data years. Only cases with known sex and race/ethnicity are included for sex and race/ethnicity estimates.

    A case definition for laboratory-confirmed cases of meningococcal disease is available from CDC. Estimates are a five-year moving average of confirmed and probable cases of meningococcal disease reported to the National Notifiable Disease Surveillance System (NNDSS).

Caveats and Limitations: 
Race/Ethnicity: Only those cases with known Race and Ethnicity are included.
Changes Between HP2010 and HP2020: 
This objective differs from Healthy People 2010 objective 14-07 in that the measure was revised from a rate per 100,000 population to a count.

Revision History

Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.

Description of Changes Since the Healthy People 2020 Launch: 
In 2013, the measure for this objective was changed from a rate per 100,000 population to the number of cases because reports of meningococcal disease occur relatively infrequently. The baseline and baseline years were revised from 0.3 cases per 100,000 (2004-2006) to 1,215 cases (2004-2008). The target was adjusted accordingly from 0.3 cases per 100,000 to 1,094 cases to reflect the revised baseline using the original target-setting method. In 2014, this measure was revised from a rate to a count. Therefore, the denominator "U.S. Population" was removed.
