National Progress Report 2020 Goal: Reduce the rate of reported acute hepatitis B virus (HBV) infections among persons aged ≥19 years to 0.50 per 100,000 population

*Rate per 100,000 U.S. population
Summary of Findings
The rate of reported acute HBV infections among persons aged ≥19 years increased from 1.31 per 100,000 U.S. population in 2016 to 1.38 per 100,000 in 2017; preventing the 2017 target of 0.83 cases per 100,000 U.S. population from being met.
Reduction needed to meet 2020 goal: A 63.8% reduction from the 2017 reported acute HBV infection rate is needed to meet the 2020 goal of 0.50 cases per 100,000 U.S. population.
This reduction can best be achieved by
- Promoting implementation of vaccine recommendations through provider education, strategic partnerships, and other measures.
- Building capacity for states to collect and use a core set of surveillance data to detect at-risk populations and gaps in vaccination coverage.
- Conducting prevention research to demonstrate how best to provide hepatitis B vaccination, testing, and treatment as part of a comprehensive set of interventions for persons who inject drugs.
- Encouraging unvaccinated persons to use HHS’s Adult Vaccine Finderexternal icon to locate providers of recommended adult vaccines and get immunized against hepatitis B.

Indicator Notes: The NNDSS is a nationwide collaboration that enables all levels of public health to share notifiable-disease-related health information. Surveillance for viral hepatitis through NNDSS is based on case definitions developed and approved by the Council of State and Territorial Epidemiologists (CSTE) and CDC. Reported cases of acute viral hepatitis B are required to meet specific clinical and laboratory criteria. Only laboratory-confirmed cases of acute viral hepatitis are presented in this report. Acute hepatitis B is reportable in all jurisdictions. Health-care providers, hospitals, and/or laboratories report cases to the local or state health department, and states voluntarily submit reports or notify CDC of newly diagnosed cases of hepatitis B that meet the surveillance case definition. Case rates per 100,000 U.S. population are calculated based on the resident population of the United States during a particular data-collection year. For census years (e.g., 2010), population counts enumerated as of April 1 are used. For all other years, population estimates as of July 1 are used.
Goal Setting: The 2020 goal of 0.50 per 100,000 U.S. population aged ≥19 years is consistent with the Healthy People 2020 Objectiveexternal icon (IID-25.1) and CDC’s Viral Hepatitis Strategic Plan, 2016-2020pdf icon[PDF – 17 pages]. Annual targets assume a constant (linear) rate of change from the observed baseline (2014) to the 2020 goal.
Limitations: Viral hepatitis is largely underreported in the NNDDS. Based on a simple, probabilistic model for estimating the proportion of patients who were symptomatic, received testing, and were reported to health officials in 2016, actual numbers of cases are estimated to be 6.5 times those reported to CDC (1). Rates may vary over time based on changes in public and provider awareness, changes in laboratory and diagnostic techniques, and changes in the definition of the condition.
