Speaker Notes
Several factors affect the risk of HIV transmission after an occupational exposure.- In a study of health care personnel who
had percutaneous exposure to HIV-infected blood, an increased risk for HIV
infection was associated with exposure to a relatively large quantity of
blood as indicated by deep injury, visible blood on the device, or a
procedure involving a needle placed in an artery or vein.
- The risk was also increased if the exposure was to blood from patients with terminal illness, possibly reflecting the higher titer of HIV in late-stage AIDS.
