Hello,
I was in a friends car. I'm not sure on their HIV status. I had a few things in their car. For example, my cigarette fell on the ground of the car. If there was blood on the ground, or the seat belt, and i touched it and then put my finger or the cigarette to my mouth, could i contract hiv?
i am afraid that i can obtain by common contact by coming in contact with dried up blood or what have it.
