If you didn't break the skin (for sure) then you have no risk.
I have a little red mark but it's just a mark, no bleeding or itching. I washed it with water after 10 minutes of the incident and I applied so alcohol gel, it did not sting.
There's something I do not understand, will the viruses (specially HIV) not be dead as the piece of glass was exposed to the air?
Yes HIV dies quickly in air. It depends on how long. Hepatitis lasts a long time in blood on surfaces.
Hep C up to 4 days in dried blood.
Hep B up to a week.
HIV is dead in 99% after several hours according to CDC. They tested high concentrations of HIV placed in blood and letting it dry and then they tested it. So the amount that would be in a tube would be a whole lot less. But those are the statistics.
But since you didn't get cut it isn't a risk.
Thanks for your reply.
One last question, if a little piece of glass stained with hiv positive blood comes in contact with a second piece of glass, will the second piece of glass be considered able to infect?
Hard to know. It is speculation and doesn't help your anxiety. I wouldn't worry about it!
But I always thought that hiv cannot be passed from object to object, in this specific case from glass to glass..
I'm not going to speculate. In this case it is not likely. If you are worried report it. But if the skin was not broken you have no exposure. If you are not sure report it and get tested.
