OPIM

hepatitis b or c virus
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
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 b1
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
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 c1
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 c2
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
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
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
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
