What is the risk of transmission after percutaneous injury of HIV?

  1. .1%

  2. .2%

  3. .3%

  4. .4%

The correct answer is: .3%

The risk of transmission after percutaneous injury of HIV is actually quite low, with a probability of only approximately 0.3%. This is because HIV is primarily transmitted through sexual contact, sharing needles, or mother-to-child transmission during pregnancy, childbirth, or breastfeeding. In contrast, percutaneous injuries (such as needlesticks) are a less common route of transmission for HIV. Additionally, the likelihood of transmission depends on factors such as the type of exposure, the amount of virus in the blood, and the type of medical treatment given after the injury. Therefore, it is important for healthcare workers to properly handle and dispose of sharp objects to minimize the risk of percutaneous HIV transmission.
