I had the opportunity to participate in a cadaver lab and accidentally suffered a needle stick from a needle that was used on a partially frozen cadaver. Is there a risk for HIV, Hep B, or Hep C infection? The poke was in my index finger and I was wearing gloves, although I did notice a small amount of blood after I removed the gloves. I'm not sure how long the cadaver had been deceased, nor am I aware of their infection status. Thank you.
