Around 292 million people worldwide may be infected with hepatitis B virus (HBV), a new modeling study shows.
Of these, 10% have been diagnosed, however, and only 5% of those eligible for treatment are receiving it, according to Dr. Homie Razavi and colleagues from the Center for Disease Analysis Foundation, a research firm in Lafayette, Colorado.
HBV is most common in sub-Saharan Africa and Asia, and mother-child transmission is the main source of new infections. While most adults who contract the virus will clear it, most infected children go on to have chronic HBV infection, leading to cirrhosis and liver cancer.
As with HIV, people with chronic infection must take medication for the rest of their lives to keep the infection under control, typically tenofovir and entecavir.
