Hello,
I want to know how long can hiv virus last in a surface that does not have visible blood?
Two days ago I went to the hospital to do a hiv test and I`ve done it, I`ve resulet hiv negative, but now i`m worried about hygiene that was there.
I suspect that the table which it was inforont of me and which is used for taking blood was not wiped and disenfected between patients who goes to do a hiv test because I saw a rapit hiv test in the table used by another patient before me.
Because they (patients) could have touched the table with finger pierced and have left cotton-picking with infected blood.
For first time that i`ve touched the table i touched her without disinfected hands and second time i`ve touched her with wet disinfected hands.
Can i be infected with hiv in this way if table was infected?
Can hiv rise again if he`s dead, in contact with something wet (disinfectant in my case) in our hands if we have small choirs and strong blood around the nails from manicure but not open and of course not bleeding choirs?
I couldn`t find a answer about a case like this.
Please help me, i`m anxious because I read in internet that virus can live outside the body for a few days and ect I`m going crazy.

Hi there, and thanks for contacting the AIDS Vancouver Helpline with your HIV/AIDS related health information. It seems you're worried about HIV transmitting through an HIV test you've had. We're happy to answer this question for you.

First off, it's great you decided to go for a test as we recommend regular HIV testing for all sexually active individuals.

This is a no risk situation, meaning it is not possible for HIV to transmit this way. What's important to consider when thinking about HIV outside the body is the ability of the virus to transmit once it is outside the body. While it may live on surfaces for a brief period, as soon as it leaves the body it is rendered in-transmissible, meaning it cannot infect you. If you consider this, then all of the situations you describe are no risk. If the virus were somehow on the surface of the table in front of you, it would not be transmissible. If the nurse somehow had a fluid on her skin (whether she disinfected her hands or not), the virus would be in-transmissible. Adding a fluid to a dried substance (blood, etc.) containing the virus would not "re-activate" the virus.

Consider, also, the transmission equation for HIV:

HIV TRANSMISSION EQUATION


BODY FLUID
+
ACTIVITY
+
DIRECT ACCESS TO BLOODSTREAM
---------- -------- ----------------------------
• blood (including menstrual) • unprotected anal or vaginal intercourse • vagina
• semen • sharing needles • anus
• pre-cum • mother to child (in specific cases) • urethra in the penis
• rectal secretions • open cuts and sores (in theory)
• vaginal fluids • other mucosal membranes
• breast milk • points of needle injection
You'll see that required for transfer are a fluid, an activity, and direct access to the bloodstream. Are you worried that somehow by touching the professional administering the test HIV will transmit? If so, you'll see that absent from that are fluids involved in transfer, an activity involved in transfer, and direct access to the bloodstream

It's important to consider that there is a bit of an assumption behind all of this that somehow the healthcare worker administering the test is not adhering to good cleaning practices. We'd argue that this is most likely not the case. Again, we stress that even if the healthcare worker was not adequately sanitizing surfaces between tests this would still not carry a risk of HIV transmission.

Thanks a lot for your question to the AIDS Vancouver Helpline, we hope it has been answered fully.
