Hepatitis B is a bloodborne pathogen disease transmitted by direct contact with blood or body fluids that contain the virus, sexual contact with an infected person, or from an infected mother to her infant during childbirth. Although the incidence of this disease has been steadily declining in the United States over the past decade, it has remained at 2.5 reported cases per 100,000 population for the past two years. The incidence of hepatitis B in Indiana continues to fall below the national average. 

In 2000, the number of reported cases of acute hepatitis B reported to the Indiana State Department of Health increased to 92 from a record low of 77 cases in 1999. One of the reported cases resulted in death.  Figure HpB1 shows reported cases of hepatitis B for the five year period, 1996-2000. 

In 2000, rates of acute hepatitis B infection varied with age. The highest rate in Indiana is found in young adults ages 20-29 (3.4/100,000 population). Figure HpB2 shows the incidence rate of acute hepatitis B by age group.

Although 64 cases were interviewed about risk factors for contracting hepatitis B, not all of those interviewed responded to each question asked (Table HpB1). Having more than one sexual partner is the highest risk factor for acquiring hepatitis B in both Indiana and the U.S.

In 2000, 25 Indiana counties reported cases of hepatitis B. Incidence for counties reporting five (5) or more cases are noted in Table HpB2.

Beginning In 2000, Indiana law requires reporting of both acute and chronic hepatitis B infection during pregnancy and perinatally exposed infants. In 2000, 67 Indiana women were identified as infectious with hepatitis B during pregnancy. Identifying these women during pregnancy facilitates appropriate medical treatment for infants.
