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 baseline was revised from 0.3 cases per 100,000 (2004-2006) to 1,215.0 cases (2004-2008) because reports of meningococcal disease occur relatively infrequently. The target was revised from 0.3 cases per 100,000 to 1,094 cases to account for the change in unit.
