This graphic shows the actual number of acute hepatitis B cases submitted to CDC and the estimated number of acute hepatitis B cases. Hepatitis B virus is a global acute and chronic communicable disease that causes major hepatic disease (Beasley & Hwang 1984). An encouraging trend is that the incidence of acute hepatitis B in the United States declined as much as 80% between 1987 and 2004, attributable to effective vaccination programs as well as universal precautions in needle use and in healthcare in general. Hepatitis means inflammation of the liver. Globally, the majority of deaths due to HBV are from complications of cirrhosis and hepatocellular carcinoma, with a small minority from acute infection. Hepatitis means inflammation of the liver. This encouraging trend might be attributable to recent advances in treatment for HBV infection; however, to the extent that the number of Americans living with chronic HBV is growing, careful clinical monitoring and continued epidemiologic surveillance remain important. Prevalence of hepatitis B and hepatitis D virus infections in the United States, 2011-2016. Listing a study does not mean it has been evaluated by the U.S. Federal Government.

More IDUs have anti-HCV than HIV infection, and viral hepatitis poses a key challenge to public health. Indeed, the prevalence rate of chronic HBV infection fell significantly among persons less than 20 years of age, from 0.2% in 1988 through 1994 to 0.03% in 2007 through 2012.

Source: Centers for Disease Control and Prevention. Although research studies often use HBsAg carrier status as a marker for chronic infection, the CDC defines chronic HBV infection as the presence of HBsAg, HBeAg, or HBV DNA in the absence of IgM antibodies to hepatitis B core antigen (IgM anti-HBc), which are seen in acute infection. A meta-analysis estimated that in 2009, 1.32 million foreign-born persons in the United States were living with chronic hepatitis B in comparison to an estimated 300,000 to 600,000 United States-born persons.

[7], The following summarizes the 2012 CDC case definition for chronic HBV infection, which is based entirely on laboratory criteria. Injection drug use and sexual exposure are the major risk factors for HBV acquisition in the United States, with injection drug use playing an increasingly important role in transmission as a result of the ongoing opioid epidemic. These estimates are based on random effects meta-analysis by world region of origin. We evaluate the cost-effectiveness of increased HBV case-finding among UK migrant populations, based on a one-time opt out case-finding approach in a primary care setting. Hepatitis B is a liver disease that results from infection with the hepatitis B virus (HBV) and is spread through contact with infected body fluids or blood products. Specific to HBV infection, NHANES does not sample individuals who are incarcerated or living homeless, and likely under samples foreign-born persons. The Epidemiology of Hepatitis B and A Infections.
