Hi, I have a question. I took my daughter to the park yesterday and she was playing in the playground and she felt down to the ground and somehow she hurt her lip and started bleeding, my question is, for example if there was dried blood there would she had been at risk for HIV if it came in contact with her mouth at the moment she felt down and cut her lip? I'm concerned. It was at a kids playgrund, so I'm sure a lot of accidents happen there, where kids get hurt often. Thank you!
