People with chronic hepatitis B virus, known as HBV, infection are at in increased risk for liver cancer, cirrhosis and are 70 percent to 85 percent more likely to die prematurely than the general population, according to the Centers for Disease Control and Prevention. With an estimated 580,000 to 2.4 million people in the U.S. infected with HBV, the CDC is now recommending that all adults should be tested for the virus at least once in their lives.
“New recommendations include hepatitis B screening using three laboratory tests at least once during a lifetime for adults aged (older than) 18 years,” the CDC said on Friday.
While vaccinations are considered highly effective at preventing HBV infections, a total 70 percent of U.S. adults reported they were unvaccinated as of 2018.
“HBV is transmitted through contact with infected blood or body fluids, such as during pregnancy or delivery, through sex, or by injection drug use (IDU), with the greatest risk for chronic infection occurring during perinatal infection,” the CDC explained.
