    Speaker Notes:

    This slide shows the decline in HBV infection in the US between 1978 and 1995.

    Mirroring the decline in the general population, the Centers for Disease Control and Prevention (CDC) estimates that the annual number of new HBV infections in health care workers has steadily declined from 12,000 in 1985 to 1000 in 1994, due in part to the widespread adoption of universal precautions, vaccination against hepatitis B, and the implementation of OSHA's Bloodborne Pathogens Standard (Moyer & Hodgson, 1996).
