i was in class when i noticed a bloody band-aid on the desk next to me. The blood seemed dried. Someone must have gotten ride of it because a guy sat down at that same desk, where the bloody band-aid used to be, and didn't seem bothered. My question is, since the band-aid was bloody and assuming it was HIV+, could the blood on it make it so that it would be unsafe to sit in that seat and use that table? Could the dry blood on the band-aid transfer HIV to the guys clothes? If he touched the dry blood and then went to the bathroom, could he get HIV? Or if i touched where the band-aid used to be, me being a woman, and then went to the bathroom or something could i get HIV? What if i get a cut after or before having touched it? Also, i want to know if it is possible to get HIV from blood if you touch it indirectly, as in touching a clothing that touched dry blood and then going to the bathroom? Is HIV transferable from object to object?

Hello,

Thank you for your inquiry.From what we gather from the question, you were asking about acquiring HIV from touching an object that has come into contact with dried blood. From the information given, this scenario is determined to be No Risk (transmission of HIV is not possible in the given scenario). In order for a risk to exist, specific HIV positive fluids must come into direct contact with the blood stream of an HIV negative person. In this scenario, there is no direct contact to the blood stream.

As stated by the CDC "HIV does not survive long outside the human body (such as on surfaces), and it cannot reproduce outside a human host" [1].
The survival time of HIV outside of the body is dependent on several factors:
1. pH level (optimum is 7.1)
2. Temperature (optimum is 37 degrees Celsius)
3. Storage in a vacuum (like a syringe) with no oxygen can allow the virus to sustain for up to 7 days.
4. HIV drying out on a surface causes a 90-99% concentration depletion over several hours.
5. At the concentrations found after drying out, there is a negligible chance of there being enough reactive virus to transmit HIV.

Recommendation: No need for HIV test with the scenario provided, refer to a physician for other health related questions
