Cut on knee – risk of transmission? Would appreciate a response as soon as possible!


Hi there,

I went to my local gym recently and worked out. When I left I noticed I had a large cut on my knee that was bleeding. I am worried about this as I knelt on the floor many times and did various exercises where the cut would have come into contact with weights/surfaces and objects

I am worried about the risk of transmission from my bleeding cut touching things in the gym?

Please could you let me know as soon as possible – do I need to test myself?

Thank you very much


Hi there,

Thank you for your inquiry. From what we gather from the question, you were asking about the risk of HIV transmission through the cut knee you described that had come into contact with the floor at your gym.

From the information given, this scenario is determined to be of No Risk (transmission of HIV is not possible in the given scenario). HIV does not transmit from environmental surface to the bloodstream. Further, HIV positive fluid becomes quickly rendered inactive when exposed to environmental surfaces. Any HIV positive fluid that you may had come into contact with would have No Risk to you when it comes to HIV transmission.

Recommendation: No need for HIV testing with the scenario provided. Please refer to health care provider for further health related questions.

All the best,
