Purpose
Hepatitis is an inflammation of the liver often caused by a virus. In the United States, the most common types of viral hepatitis are hepatitis A, hepatitis B, and hepatitis C. While each can produce similar symptoms, each hepatitis virus affects the liver differently, has different routes of transmission and infection, and typically affects different populations.
Fortunately, effective vaccines are available to help prevent hepatitis A and hepatitis B, and there is treatment for hepatitis B. Although no vaccine is available for hepatitis C, treatment can cure infection from the virus. Learn more about the different viral hepatitis types.

How the data are used
The Viral Hepatitis Surveillance Report — United States, 2022 presents information from the ongoing, systematic collection, analysis, and interpretation of viral hepatitis-related data. The surveillance process is essential to monitor trends that inform planning, implementation, and evaluation that are needed to improve viral hepatitis public health policy and practice in support of national viral hepatitis elimination goals.
Key findings
Variations of disease rates by race or ethnicity may reflect systemic cultural, behavioral, environmental, and social factors.
Hepatitis A

Hepatitis B
During 2022, 47 states and the District of Columbia reported 2,126 acute hepatitis B cases, corresponding to 13,800 estimated acute hepatitis B virus (HBV) infections; 44 states and the District of Columbia had a total of 16,729 newly reported chronic hepatitis B cases.
Acute hepatitis B rate remained stable during 2022
After annual decreases during 2020–2021, the rate of acute hepatitis B remained stable between 2021 and 2022.
- Rate of acute hepatitis B is highest in non-Hispanic Black populations: The rate of acute hepatitis B among non-Hispanic Black persons increased by 11.1% during 2021–2022 and was 1.7 times as high as the rate among non-Hispanic White persons.
- Rate of hepatitis B-related deaths is highest in non-Hispanic Asian/Pacific Islander (A/PI) populations: The rates of reported hepatitis B-related deaths among non-Hispanic A/PI persons and non-Hispanic Black persons were 8.5 times and 2.6 times as high as the rate among non-Hispanic White persons, respectively.
Hepatitis C
During 2022, 46 states and the District of Columbia reported a total of 4,848 acute hepatitis C cases corresponding to 67,400 estimated acute hepatitis C virus (HCV) infections; 43 states and the District of Columbia had a total of 93,805 newly reported chronic hepatitis C cases.
Acute hepatitis C rate decreased during 2022

- Rate of acute hepatitis C is highest in non-Hispanic American Indian/Alaska Native (AI/AN) populations: Although the rate of acute hepatitis C among non-Hispanic White persons decreased during 2021–2022, the rate among non-Hispanic AI/AN persons increased by 7.4% and was 1.9 times as high as the rate among non-Hispanic White persons.
- Rate of hepatitis C-related deaths is highest in non-Hispanic American Indian/Alaska Native (AI/AN) and non-Hispanic Black persons: The rates of reported hepatitis C-related deaths among non-Hispanic AI/AN persons and non-Hispanic Black persons were 3.3 times and 1.7 times as high as the rate among non-Hispanic White persons, respectively.
