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? What is the HIV risk from discarded needles?.What is the risk from needlestick injuries in healthcare settings?.How many cases of HIV have resulted from occupational needlestick injuries?. ![]() There have been no documented cases of HIV infection through contact with needles in this way. Injuries from discarded needles in the community (non-occupational exposure) are less common and infections rare. As described below, documented cases of HIV infection following an injury are extremely rare. It is estimated that around three million such needlestick injuries take place globally each year, including one million in Europe, although not all such injuries are reported. Needlestick injuries are most like to happen among healthcare workers who are accidentally exposed to infected blood (occupational exposure).
