The U.S. Preventive Services Task Force (USPSTF) recommends hepatitis B virus (HBV) screening for nonpregnant high-risk adolescents and adults, according to a recommendation statement being published in Annals of Internal Medicine.
Up to 2.2 million people in the United States have chronic HBV,
and 15 to 25 percent of those infected will die from liver disease or
liver cancer. Screening for HBV could identify those who may benefit
from treatment. Most people born in the United States have been
vaccinated for HBV, which is the most effective way to prevent
infection. However, there are some characteristics that put people at
high risk. Those at high risk for HBV infection include persons born in countries with a high prevalence of HBV infection;
U.S. citizens not vaccinated in infancy and whose parents are from a
high-risk country; HIV-positive persons; injection drug users; those who
have household contact with someone infected with HBV; and men who have
sex with men.
Researchers conducted a systematic review of published evidence to assess the benefits and harms of screening high-risk individuals for HBV. They conclude with moderate certainty that screening for HBV infection in high-risk individuals
has moderate net benefit. The recommendation applies to asymptomatic,
nonpregnant adolescents and adults who have not been vaccinated and
other persons at high risk. This is an update to a 2004 recommendation.
Previously, the USPSTF focused its recommendation on only the general
