Summary
This report updates and consolidates all previous U.S. Public Health
Service recommendations for the management of health-care personnel (HCP)
who have occupational exposure to blood and other body fluids that might
contain hepatitis B virus (HBV), hepatitis C virus (HCV), or human immunodeficiency
virus (HIV). Recommendations for HBV postexposure management include initiation
of the hepatitis B vaccine series to any susceptible, unvaccinated person
who sustains an occupational blood or body fluid exposure. Postexposure
prophylaxis (PEP) with hepatitis B immune globulin (HBIG) and/or hepatitis
B vaccine series should be considered for occupational exposures after
evaluation of the hepatitis B surface antigen status of the source and
the vaccination and vaccine-response status of the exposed person. Guidance
is provided to clinicians and exposed HCP for selecting the appropriate
HBV PEP.
Immune globulin and antiviral agents (e.g., interferon with or without
ribavirin) are not recommended for PEP of hepatitis C. For HCV postexposure
management, the HCV status of the source and the exposed person should
be determined, and for HCP exposed to an HCV positive source, follow-up
HCV testing should be performed to determine if infection develops.
Recommendations for HIV PEP include a basic 4-week regimen of two
drugs (zidovudine [ZDV] and lamivudine [3TC]; 3TC and stavudine [d4T];
or didanosine [ddI] and d4T) for most HIV exposures and an expanded regimen
that includes the addition of a third drug for HIV exposures that pose
an increased risk for transmission. When the source person's virus is
known or suspected to be resistant to one or more of the drugs considered
for the PEP regimen, the selection of drugs to which the source person's
virus is unlikely to be resistant is recommended.
In addition, this report outlines several special circumstances (e.g.,
delayed exposure report, unknown source person, pregnancy in the exposed
person, resistance of the source virus to antiretroviral agents, or toxicity
of the PEP regimen) when consultation with local experts and/or the National
Clinicians' Post-Exposure Prophylaxis Hotline ([PEPline] 1-888-448-4911)
is advised.
Occupational exposures should be considered urgent medical concerns
to ensure timely postexposure management and administration of HBIG, hepatitis
B vaccine, and/or HIV PEP.
