Hepatitis b or c virus l.jpg
Hepatitis B or C Virus

  • Inflammation of the liver

  • Causes liver damage ranging from mild to fatal

  • Can live in a dry environment for at least 7 days


Hbv hepatitis b l.jpg
HBV -Hepatitis B

  • Very infectious

    • 1/3 no symptoms, 1/3 flu-like, 1/3 severe

    • 6 to 10% of cases infectious for life (carrier state)

  • In the past, 140,000-300,000 new infections per year

    • 5,000-6,000 deaths/yr from chronic liver disease

  • Safe and effective vaccine is now available

    • Many HCW are not vaccinated


Hbv hepatitis b10 l.jpg
HBV - Hepatitis B

Health Care Workers and HBV

  • Approximately 400 HCW infected annually

  • This is a decrease from 17, 000 in 1983 and 1,000 in 1994.

  • 25% of infected develop acute hepatitis

  • 10-30% of health/dental workers show evidence of past HBV infection


Hcv hepatitis c l.jpg
HCV - Hepatitis C

  • Affects 4 times more people than HIV

  • 4 million Americans infected

  • Only 25% of those infected have been diagnosed

  • In 1995, estimated 560-1120 cases among HCW in U.S.


Hcv hepatitis c12 l.jpg
HCV - Hepatitis C

  • Symptoms may or may not be present

  • Infection may lead to carrier state

  • Carrier state can develop with or without symptoms

  • Carrier state can lead to chronic liver disease, cirrhosis (10 year latency), or cancer (alcohol is strong co-factor)

  • Leading cause of liver transplant in U.S.


Hcv hepatitis c13 l.jpg
HCV - Hepatitis C

  • 85% of Hepatitis C infections persist for life

  • 70% develop chronic liver disease

  • Signs and symptoms may not appear until 10 years after infection

  • Onset of symptoms may present with severe liver disease

  • No broadly effective treatment

  • No vaccine available


Hcv risk factors l.jpg
HCV - Risk Factors

  • Blood transfusion prior to 1992

  • IV drug use

  • Unprotected sex (multiple sexual partners)

  • Occupational percutaneous exposure to blood with contaminated sharp

    • Risk is intermediate between Hepatitis B and HIV


Human immunodeficiency virus hiv l.jpg
Human Immunodeficiency Virus (HIV)

  • Attacks the human immune system

  • Can live in a dry environment for only a few hours

  • > 1 million infections in U.S.

  • 56 documented cases among HCW;

  • 138 cases of possible occupational transmission


Slide16 l.jpg
AIDS

  • AIDS = Acquired Immunodeficiency Syndrome

  • Results from destruction of the human immune system from infection with HIV

  • Some have no symptoms, or less severe symptoms

  • No vaccine available yet


Hbv hiv compared l.jpg

HBV HIV

  • HCW cases 400/yr. 56

    • Needle stick 6-30/100 1/300

  • Vaccine available Yes No
