Hello! I work in a busy clinical laboratory but I do paper works. We'll one time, I went inside the area where the technologists are processing some specimen. I was looking for a pen at that point when I saw one and just grabbed it to sign a document. After few minutes, I went to the restroom to pee and by then I touched the urethra of my penis briefly. I then realized that I did not wash my hands at all after touching the pen inside the laboratory. The pen has been lying around and who knows if it was contaminated with HIV. I did not feel any wetness or did see any red spot in the pen but it has been lying near some machines for quite sometime which I was not sure if some blood specimen has touched it though I did not see or feel anything unusual from the pen. I am probably a little anxious but then in case something infectious got in contact with the pen, could it get transferred to my hand and then from my hand to my urethra? Thank you so much.
No matter what creative uses for a pen a person can come up with, it will not transmit HIV. HIV does not live well on inanimate objects.
While traces of the virus can be found on some surfaces (especially if wettish) for days, the number of viruses drops quickly to levels below a threshold that can infect someone who then places the pen in a place HIV likes to go (use your imagination).
HIV therefore is very different than flu or Ebola. Sex and needles are the overwhelming modes of HIV transmission. If casual contact spread this virus we would have a billion infected people rather than 40 million.
