Sharps injury or needlestick is a constant fear, with the focus being on the possible transmission of HIV or of Hepatitis B or C, and the associated psychological trauma that goes along with the fear of infection.
But there is more than just HIV and Hep B/C to fear, as we have noted previously on the Clinical Waste Discussion Forum.
In the laboratory, handling of a wide variety of pathogenic virus, fungi, bacteria, and others, the unavoidable use of sharps in the laboratory can result in a wide range of sometimes exotic infections.
The US CDC has reported a rare vaccinia virus infection following needlestick injury to a vaccinated lab worker.
