Viral Hepatitis

This report presents recommendations for postexposure interventions to prevent hepatitis B virus, hepatitis C virus, or HIV infections and tetanus in persons wounded in bombings or events causing mass casualties. During such events, wounded persons may be exposed to blood, body fluids, or tissue from other injured persons, putting them at risk for bloodborne infections.

This report describes the burden of acute disease attributed to infection with the hepatitis A, hepatitis B, and hepatitis C viruses, and describes acute disease trends in recent years. Cases of acute viral hepatitis are reported weekly by state and territorial health departments to CDC's National Notifiable Diseases Surveillance System. The report includes the methods of collecting data, definitions for acute viral hepatitis, and analyses.

This information sheet, for the general public, discusses the hepatitis B virus (HBV). It explains HBV, risk factors for contracting HBV, transmission, symptoms, diagnosis, and treatment of acute and chronic HBV infection. It discusses ways of preventing HBV including vaccination, and provides a list of facts about the disease.

This YouTube video is a public service announcement that encourages individuals including pregnant women to get tested, and to have their babies vaccinated for hepatitis B.

This YouTube video contains a series of Public Service Announcements (PSA), encouraging individuals including pregnant women to get tested, and to have their babies vaccinated for hepatitis B.

This pamphlet provides information about hepatitis B, a viral disease that affects the liver. It discusses the liver and how it is affected by the hepatitis B virus (HBV), what is chronic hepatitis B, who gets HBV, its transmission and symptoms, diagnosis, and treatment such as liver transplantation if chronic hepatitis B causes liver failure. The pamphlet also discusses HBV prevention including vaccination, what to do if exposed to HBV, getting tested and early treatment to prevent liver damage, and participating in clinical trials. The pamphlet also provides contacts for more information.

This report provides information on the National Immunization Survey (NIS) which estimated vaccination coverage among children aged 19-35 months for 50 states and selected local areas. It describes the 2008 NIS coverage estimates for the 4:3:1:3:3:1 series and individual vaccines, 7-valent pneumococcal conjugate vaccine, =2 dose of Hepatitis A vaccine, and hepatitis B vaccine among children born during January 2005 - June 2007. Results demonstrate that the nation’s immunization program remained successful in maintaining high vaccination rates among young children.

This study discusses information on the 184 syringe exchange programs (SEPs) operating in 36 states, the District of Columbia, and Puerto Rico. Of these SEPs, 67% completed a mail/telephone survey conducted by North American Syringe Exchange Network (NASEN) and Beth Israel Medical Center, New York, which covered program operations for 2008. The report summarizes findings from the survey and compares them with results from a previous SEP survey for 1994-2007.

In this study, CDC reports on assessed hepatitis A vaccine coverage among children aged 12-23 months from 2006-2009, using data from eight Immunization Information System sentinel sites. Average hepatitis A vaccination coverage with =1 dose at the sites increased from 17 percent in 2006 to 47 percent in 2009. Average full vaccination coverage with =2 vaccine doses through age 23 months increased from one percent in 2006 to 15 percent in 2009. Vaccine coverage with =1 dose increased most during 2006 through the first quarter of 2007, then slowed.

This report describes CDC comparison of acute hepatitis C virus (HCV) surveillance data reported in 2008 from the National Notifiable Diseases Surveillance System (NNDS) and the Emerging Infections Program (EIP), which conducts enhanced surveillance for acute hepatitis C in selected states. Results show that 26 of 120 cases reported from EIP-funded sites were missing from NNDSS. Data on race and major HCV risk factors were missing from 22 percent and 60 percent of reports in NNDSS, compared with 8 percent and 25 percent of reports in EIP, respectively.
