Abstract
The risk of occupationally acquired human immunodeficiency virus (HIV) infection in exposed health-care workers has been estimated to be 0.5% after accidental needlestick with an HIV- contaminated needle. Needlestick injuries resulting in parenteral exposure to HIV-infected material are the most common reported cause of occupational HIV infection in health-care workers. With 60% of these exposures unpreventable even with strict adherence to current infection control procedures, it is necessary to develop technical changes in work protection in order to further reduce the risk.
