Exposure may include accidental exposure to HIV-infected blood following a needlestick injury or cut from a surgical instrument In UK guidelines, PEP is therefore no longer recommended following occupational exposure to a source with an undetectable viral load.Įxposure to HIV as a result of work (job) activities. Due to the effectiveness of HIV treatment, the blood of someone living with HIV in the UK could well have no detectable virus (Undetectable equals untransmittable, U=U), lowering that risk even further. However, the reviews of transmission probability upon which this calculation is based date predominantly from the 1980s and 1990s, before the wide-scale introduction of antiretroviral therapy. The risk of transmission from a needlestick involving HIV-containing blood has been estimated at 0.23%, or just over one in 500. What is the risk from needlestick injuries in healthcare settings? Three-quarters of these took PEP, and almost all did so within 24 hours, with no HIV infections as a result. The number of cases of HIV acquisition following an accidental needlestick injury globally is thought to be around 100 people in total.īetween 20, a total of 1478 healthcare workers were reported as having been exposed to patient blood containing HIV in the UK. In the UK, there have only ever been five definite cases of HIV infection following a needlestick injury in a healthcare setting, and none reported in the past 20 years. In the US, there were a total of 58 cases of confirmed occupational transmission of HIV to healthcare workers up to 2013, with only one since 1999. How many cases of HIV have resulted from occupational needlestick injuries? ![]()
