HepTracker overview
Data available on the dashboard are from two sources: 1) case surveillance data collected through the Centers for Disease Control and Prevention's (CDC) National Notifiable Diseases Surveillance System (NNDSS) and 2) mortality data from CDC's National Vital Statistics System (NVSS). Case reports for hepatitis A, hepatitis B (acute, chronic, and perinatal), and hepatitis C (acute, chronic, and perinatal) infections are collected by local and state health departments and submitted to CDC. Cases are classified based on CSTE case definitions and CDC case reporting guidance. Because of varying state laws, resources, and available infrastructure, surveillance for viral hepatitis is subject to underreporting and under ascertainment. For more information, please see Technical Notes.
Select a condition and topic of interest
Data are available for hepatitis A, hepatitis B, and hepatitis C―within each condition, users may select a topic of interest from the left side of the page:
- Hepatitis A: cases and mortality
- Hepatitis B: acute, chronic, perinatal, and mortality
- Hepatitis C: acute, chronic, perinatal, and mortality
Data are presented by year, state, sex, age group, and race and ethnicity. Risk and exposure information is presented for acute infections only. Data summaries are available for each topic of interest by clicking the "Surveillance Summary" button located on the left side of each page.
Select years of interest
Data can be viewed for several years or for a single year using the "Year Range" filter available on the left side of each page. The user can use the slider bar to select year(s) or type the year range in the input boxes.
Select ways to view data
Data can be displayed as a figure (default) or table; to display data as a table right-click the figure and select “Show as a table” or click the table icon 
(when available this is displayed on the top right of the figure box). Hovering over a particular data point in a figure will display detailed information. Maps can be enlarged by clicking on the focus icon 
, other figures can be enlarged by right-clicking the figure and selecting “Show as a table”. Figures are not directly downloadable but can be copied into documents by right-clicking and selecting “copy image”.
Please note some features such as "Include" and "Exclude" are sometimes available in the right-click menu of a visual. It is recommended users do not utilize these features. If these features are selected, users must refresh the page to return the dashboard to original settings.
- Data presented throughout the dashboard are not adjusted for under ascertainment and underreporting. Case count estimations for acute conditions (adjusted for under ascertainment and underreporting) are available in the condition-specific surveillance summaries. Data are presented for reported confirmed cases according to CSTE case definition. See Technical Notes for more information.
- State-level demographic information is not available based on current data sharing permissions.
Data sources and footnotes
Sources
1. CDC, National Notifiable Diseases Surveillance System. Reported confirmed cases only. Data updated as of December 9, 2025.
2. CDC, National Center for Health Statistics (NCHS), Multiple Cause of Death on CDC WONDER online database. Data updated as of January 12, 2026. Data are based on information from all death certificates filed in the vital records offices of the 50 states and the District of Columbia through the Vital Statistics Cooperative Program or coded by NCHS from copies of the original death certificates provided to NCHS by the State registration offices. Deaths of nonresidents (for example, nonresident aliens, nationals living abroad, residents of Puerto Rico, Guam, the Virgin Islands, and other US territories) and fetal deaths are excluded.

Footnotes
† Rates calculated per 100,000 population. For maps, data are displayed for the most recent year based on user selection in the "Year Range" filter.
§ NA: Not applicable, case data that was not reported (—), unavailable (U), or not reportable (N) for jurisdiction for MMWR year. For no reported cases, the reporting jurisdiction did not submit cases to CDC. For not reportable, the disease or condition was not reportable by law, statute, or regulation in the reporting jurisdiction. Please see Technical Notes for more information.
¶ Race and ethnicity categories include non-Hispanic American Indian or Alaskan Native (AI/AN), non-Hispanic Black (Black), non-Hispanic White (White), non-Hispanic Asian and Pacific Islander (A/PI), and Hispanic. Due to small counts, for hepatitis A-related mortality only, race and ethnicity categories were collapsed into two categories; non-Hispanic White and Other (including non-Hispanic American Indian or Alaskan Native, non-Hispanic Black, non-Hispanic Asian and Pacific Islander, and Hispanic).
**Age is presented in years.
†† Hepatitis A: Case reports with at least one of the following risk behaviors/exposures reported 2–6 weeks prior to symptom onset or documented seroconversion if asymptomatic: 1) household contact; 2) injection drug use; 3) international travel; 4) men who have sex with men (MSM); 5) other contact; 6) sexual contact. Reported cases may include more than one risk behavior/exposure. Cases with more than one type of contact reported were categorized according to a hierarchy: 1) sexual contact; 2) household contact (nonsexual); and 3) other contact with hepatitis A case. Risk exposure data for international travel might not match prior publications due to inclusion of any reported international travel during the exposure window (prior publications restricted to hepatitis A-endemic regions).
§§ Cause of death is defined as one of the multiple causes of death and is based on the International Classification of Diseases, 10th Revision (ICD-10) codes for hepatitis A (B15), hepatitis B (B16, B17.0, B18.0, B18.1), and hepatitis C (B17.1, B18.2).
¶¶ Death rates for race/ethnicity, sex, and the overall total are age-adjusted per 100,000 US standard population during 2000 by using the following age group distribution (in years): <1, 1–4, 5–14, 15–24, 25–34, 35–44, 45–54, 55–64, 65–74, 75–84, and ≥85. For age-adjusted death rates, the age-specific death rate is rounded to one decimal place before proceeding to the next step in the calculation of age-adjusted death rates for NCHS Multiple Cause of Death on CDC WONDER. This rounding step might affect the precision of rates calculated for small numbers of deaths. Missing data are not included.
*** S/UR: Death data were suppressed (S) (when no value for counts) or unreliable (UR) (when no value for rates).
Data are suppressed in order to prevent revealing information that may identify specific individuals, small data values are not available when the count falls below a ratio of the representative demographic population.
Unreliable rates occur where death counts were less than 20 and are not displayed because of the instability associated with those rates.
††† US Department of Health and Human Services regions were categorized according to the grouping of states and US territories assigned under each of the 10 Health and Human Services regional offices. For the purposes of this report, regions with US territories (Region 2 and Region 9) contain data from states only.
§§§ Hepatitis B: Case reports with at least one of the following risk behaviors/exposures reported 6 weeks to 6 months prior to symptom onset or documented seroconversion if asymptomatic: 1) dialysis patient; 2) household contact with suspected/confirmed hepatitis B case; 3) injection drug use; 4) men who have sex with men (MSM); 5) multiple sexual partners; 6) sustained a percutaneous injury (needlestick); 7) occupational exposure to blood; 9) underwent surgery; and 10) transfusion. Reported cases may include more than one risk behavior/exposure. Cases with more than one type of contact reported were categorized according to a hierarchy: (1) sexual contact; (2) household contact (nonsexual). Hepatitis B transmission associated with surgery, dialysis, or transfusion is extremely rare in the United States; thus, the reporting of these exposures might simply represent recent receipt of these health care procedures and do not necessarily indicate these procedures were associated with hepatitis B virus (HBV) transmission. Risk exposure data for dialysis might not match prior publications due to a minor change in counting methodology.
¶¶¶ Hepatitis C: Case reports with at least one of the following risk behaviors/exposures reported 6 weeks to 6 months prior to symptom onset or documented seroconversion if asymptomatic: 1) transfusion; 2) underwent surgery; 3) sexual contact with suspected/confirmed hepatitis C case; 4) occupational exposure to blood; 5) sustained a percutaneous injury (needlestick); 6) multiple sexual partners; 7) men who have sex with men (MSM); 8) injection drug use; 9) household contact with suspect/confirmed hepatitis C case; and 10) dialysis patient. Reported cases may include more than one risk behavior/exposure. Cases with more than one type of contact reported were categorized according to a hierarchy: (1) sexual contact; (2) household contact (nonsexual). Hepatitis C virus (HCV) transmission associated with surgery, dialysis, or transfusion is extremely rare in the United States; thus, the reporting of these exposures might represent a history of recent receipt of these health care procedures and do not necessarily indicate these procedures were associated with HCV transmission. Risk exposure data for dialysis might not match prior publications due to a minor change in counting methodology.
**** Perinatal hepatitis C cases became nationally notifiable in 2018.
