This video describes HIV viral replication and where antiretroviral drugs work in the replication process.

This report discusses the hepatitis C virus (HCV), how it is treated, and how it can be prevented. The report examines the epidemiology of HCV. It discusses the screening tests, history, general treatment, and postexposure prophylaxis for HCV. The report explains the ways that HCV can be transmitted from person to person and how the virus can be spread through bodily fluid. It identifies the most serious high risk behaviors such as injection drug use and certain sexual practices. The report cites the risks associated with health care work.

This guideline is intended to provide a framework and understanding of the diagnostic approaches to TB infection/disease and to present a classification scheme that facilitates management of all persons who have had diagnostic tests.

This report updates previous US Public Health Service recommendations for the management of health-care personnel (HCP) who have occupational exposure to blood and other body fluids that may contain Hepatitis B, Hepatitis C, or HIV/AIDS. It contains recommendations for Hepatitis B Virus postexposure management including initiation of hepatitis B vaccine series to any susceptible, unvaccinated person who sustains blood or body fluid exposure. Guidance is provided to clinicians and exposed HCP for selecting the appropriate HBV postexposure prophylaxis (PEP).

This comprehensive plan for health care professionals and policy makers addresses the prevention and control of hepatitis C virus (HCV) infection and its consequences. This strategy strives to protect the public's health by outlining guidelines for prevention and control of HCV infection, providing credible information on hepatitis C to enhance healthy decisions and promoting healthy living through strong partnerships with national, state, and local organizations in both the public and private sectors.

This webinar includes a panel of experts discussing the questions healthcare providers have about using 3 months of isoniazid and rifapentine once weekly (3HP) to treat latent TB infection (LTBI).

This resource is a search engine tool designed for health care practitioners to quickly find topic-specific information on TB. This resource is being developed by Mayo Clinic physicians who have expertise in this field. Users may enter search criteria on a variety of TB topics and the search engine will then display records with information pertaining to their topic. Along with topic information, links are provided to outside sources and other internal resources.

This Web site provides interim guidance for clinicians who treat immune compromised persons, including HIV-infected adults and adolescents. The page explains that persons with low CD4 cell counts or AIDS can experience more severe complications of seasonal influenza, and possibly HIV-infected adults and adolescents are at higher risk for swine-origin influenza complications.

This information sheet is a reminder about the guidelines for preventing transmission of hepatitis B virus and other bloodborne pathogens from the use of finger stick devices. It explains fingerstick devices and their use, reasons why reusable devices should never be used for more than one person, when single-use auto-disabling fingerstick devices should be used, recommendations for persons performing fingerstick procedures to ensure that they are not placing persons in their care at risk for infection, and contacts for additional information.

This information sheet, in the form of a chart, makes recommendations regarding vaccinations for persons with hepatitis C virus (HCV) infection. The information sheet discusses the following vaccines: hepatitis A (HepA); hepatitis B (HepB); human papillomavirus (HPV); influenza; measles, mumps, rubella (MMR); meningococcal (MCV4, MPSV4); pneumococcal polysaccharide (PPSV23); tetanus, diptheria, whooping cough (pertussis) (Tdap, Td); varicella (chickenpox); and zoster (shingles).
