If me and infected person both fall off the bicycle and both got peeled off the skin on hand or leg and our wounds will touch it would be risk when wounds are activity bleeeding?
Thank you for your inquiry. From what we gather from the question, you were asking about whether or not you could acquire HIV from someone else's wound when they are activity bleeding. From the information given, this scenario is determined to be Negligible Risk (There is no evidence or no documented cases of transmission. However, there is a theoretical possibility of transmission under certain extenuating circumstances.)
Since HIV becomes inactive when exposed to oxygen, it is likely that the HIV+ person's blood would not be able to transmit the virus once it has left their body. Of course there are extenuating circumstances that may be considered high risk activities. For example, if two people have open bleeding wounds and they rub each others wounds against each other (without any exposure to oxygen in between) and the blood between the two is interchanged from individual to individual, there could be the possibility of transmission.
Recommendation: There are no evidence or no documented cases of transmission. Refer to a healthcare professional for more personalized answers.
