What you need to know

​​The word “hepatitis" means inflammation of the liver. Hepatitis is most often caused by one of several viruses, which is why it is often called viral hepatitis. In the United States, the most common types of viral hepatitis are Hepatitis A, Hepatitis B and Hepatitis C.

Testing for hepatitis is crucial

Chronic hepatitis often does not cause any symptoms until serious liver damage has been done Find out if you should be tested by taking a 5 minute online Hepatitis Risk Assessment. This online assessment is designed to determine an individual's risk for viral hepatitis by asking questions based on CDC's guidelines for testing and vaccination. The Assessment allows individuals to answer questions privately and print their recommendations to discuss with their doctor.

Chronic Hepatitis can lead to Liver Cancer

Unlike Hepatitis A, which does not cause a long-term infection, Hepatitis B and Hepatitis C can become chronic, life-long infections. Chronic viral hepatitis can lead to serious liver problems including liver cancer. More than 4 million Americans are living with chronic Hepatitis B or chronic Hepatitis C in the United States, but most do not know they are infected.

Both Hepatitis B and Hepatitis C can cause liver cancer and have contributed to the increase in rates of liver cancer in recent decades. At least half of new cases of liver cancer are from chronic Hepatitis C.

Priority Populations and Liver Cancer

Some population groups are disproportionately affected by viral hepatitis-related liver cancer. The number of new cases of liver cancer is highest in Asian and Pacific Islanders and is increasing among African Americans, baby boomers, and men.

With early detection, many people can get lifesaving care and treatment that can limit disease progression, and prevent cancer deaths.

Vaccine-preventable: Hepatitis A and Hepatitis B

Hepatitis A and Hepatitis B can both be prevented with vaccines. Cases of Hepatitis A have dramatically declined in the United States over the last 20 years largely due to vaccination efforts. The Hepatitis A vaccine is recommended for all children at one year of age and for adults who may be at increased risk.

Unfortunately, many people became infected with Hepatitis B before the Hepatitis B vaccine was widely available. The Hepatitis B vaccine is now recommended for all infants at birth and for adults who may be at increased risk.
