Infection prevention and control in the era of the AIDS/HIV epidemic

The chronology of important events in the AIDS/HIV epidemic is presented in Table 2. Nurses are the largest group of health care workers and persons who provide direct care and handle sharp objects regularly. As the number of persons infected with HIV increases and as more infected persons become ill enough to require care, the opportunity for an individual nurse to have contact with an infected person will increase. Because many persons with HIV infection also have Kaposi's sarcoma and other malignancies, some oncology nurses may have more contact with HIV-infected individuals than nurses in general. However, it is well established that the major risk for HIV infection is from puncture injuries, and a number of strategies are available and are being developed to make needle and sharps handling safer. Nurses must take personal responsibility for knowing how to reduce their own risks for exposure to HIV and other infectious agents while keeping in mind the need not to increase risks of nosocomial infections in patients. Thus, all nurses need a comprehensive understanding of the purposes of barriers (eg, gloves, gowns, masks, handwashing, room assignment) and when and how to use them correctly. In addition, all nurses who have contact with blood and body fluids should take responsibility for their own immunity to hepatitis B by obtaining hepatitis B vaccination. By using all of these strategies in combination, many infection risks to nurses and patients will be minimized.
