About the National Data

Data

Data Source:  National Notifiable Diseases Surveillance System (NNDSS), CDC/CSELS

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

Comparable HP2020 objective
Retained, which includes core objectives that are continuing from Healthy People 2020 with no change in measurement.
