Reduce cases of pertussis among infants — IID‑05 Data Methodology and Measurement

About the National Data

Data

Baseline: 2,651 cases of pertussis occurred annually among children under 1 year during 2014-18

Target: 2,387 cases

Numerator
Number of confirmed and probable cases of pertussis among children under 1 year.
Target-setting method
Percent improvement
Target-setting method details
10 percent improvement from the baseline.
Target-setting method justification
Trend data were not available for this objective. A 10 percent improvement from the baseline was used to calculate a target. This method was used because given the increase seen in case counts in data from the Healthy People 2020 objective, the Healthy People 2030 Workgroup Subject Matter Experts selected a more conservative target.

Methodology

Methodology notes

Estimates represent the mean number of confirmed, probable and unknown cases (aged < 1 year). A case definition for confirmed and probable cases of pertussis is available from CDC. Estimates are a five-year moving average of confirmed, probable and unknown cases of pertussis reported to the National Notifiable Diseases Surveillance System (NNDSS).

History
