Children and adolescents in the U.S. today have a very low likelihood of hepatitis B virus (HBV) infection thanks to widespread vaccination, according to an epidemiological study described in the March 1, 2011, Annals of Internal Medicine. Many adults remain vulnerable, however, underlining the importance of vaccination for at-risk groups.

In late December, Dynavax Technologies reported findings from a small early clinical trial showing that its investigational hepatitis B virus (HBV) therapeutic vaccine DV-601 -- intended to help control the virus in people already infected, rather than prevent infection -- was well tolerated and produced immunological and virological responses at all dose levels. Larger studies are needed, however, to show whether the vaccine is clinically effective.

Women with hepatitis B virus (HBV) infection who were hepatitis B "e" antigen (HBeAg) positive and had high HBV DNA viral load during pregnancy were more likely to transmit the virus to their infants, even though the babies received HBV prophylaxis, according to a Canadian study described in the June 11, 2010 advance online edition of the Journal of Viral Hepatitis.

Treatment with the nucleoside analog telbivudine (Tyzeka) and birth by elective Cesarean section both reduced the likelihood of hepatitis B virus (HBV) transmission from mothers to infants during pregnancy and delivery, according to 2 separate studies presented at the recent American Association for the Study of Liver Diseases "Liver Meeting" (AASLD 2010) this week in Boston. Emergency Cesarean delivery, however, was associated with a trend toward increased transmission risk.

The prevalence of past and present hepatitis B virus (HBV) infection fell by nearly 70% among children in a large household survey of U.S. residents a decade after the introduction of universal HBV vaccination, according to a report by Centers for Disease Control and Prevention (CDC) researchers published in the July 15, 2010 Journal of Infectious Diseases. Hepatitis B prevalence among adults remains high, however, varying considerably among racial/ethnic groups and much greater among foreign-born individuals.

As many as 1 in 5 cases of acute hepatitis B virus (HBV) infection in the U.S. may be attributable to exposure in healthcare settings, especially long-term care facilities, according to research presented last week at the 50th Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC 2010) in Boston.

Coinciding with National Hepatitis B Awareness Month, San Francisco Hep B Free launched a new ad campaign this week to raise awareness about hepatitis B within the city's Asian communities, and to encourage testing and vaccination. The campaign includes print and television ads in several languages (including Chinese, Korean, and Vietnamese) as well as information directed at English-speaking medical providers. Asian Americans have a high rate of hepatitis B -- an estimated 1 in 10 infected -- and San Francisco, with its large Asian population, has the nation's highest rate of liver cancer.
