US&A (v. 2/07) 72 Top 11 Most Frequently Asked Questions About Viral Hepatitis
US&A (v. 2/07) 73 What is Chronic HBV? Life-long liver disease caused by infection with HBV These people are infected for life and can spread the disease to others
US&A (v. 2/07) 74 Will I die from Hepatitis B? Most people do not die from it. There are cases where Hepatitis B can cause liver damage (cirrhosis) that does not go away. Hepatitis B can also cause liver cancer, which may lead to death. Good medical care can make your risk less for these.
US&A (v. 2/07) 75 Treatment for Chronic Hepatitis B Check with your doctor about treatment for chronic hepatitis B. Most people with chronic hepatitis B will remain carriers of the virus if they do not get treated. The best things carriers can do: –make sure their babies get all of their hepatitis B shots –make sure they do not spread it to others –get good health care
US&A (v. 2/07) 76 Booster Doses and Post-vaccination Testing Vaccine-induced hepatitis B surface antibody levels may decline over time; however, immune memory remains intact indefinitely following immunization. Persons with declining antibody levels are still protected against clinical illness and chronic disease. After routine vaccination of infants, children, adolescents or adults, post-vaccination testing for adequate antibody response is not necessary Source: CDC, 2003
US&A (v. 2/07) 77 If my hepatitis B vaccination series is interrupted, do I have to start over? No. If the vaccination series is interrupted, resume with the next dose in the series.
