Dried 3 day blood in condom

Question: 

about a month ago from an online buying/selling application I bough some condoms and they arrived about 3 days later and on the same day I used one of the condoms and ejaculated in the condom. Even though the condoms looked sealed I am still scared that the person I bought it from might have done something to it. what if this person was HIV positive and he put some of his blood or semen into this condoms and packed it and sent it to me. I know this sounds crazy but I am super worried because few days ago I got this dry little rash thing on my penis shaft which looks a lot like eczema and less like a rash but I am still scared. can someone please tell me if its possible for me to get HIV in this scenario? can dried blood that gets in touch with penis urethra give me hiv?

Answer: 

Hello,

Thank you for your inquiry. From what we gather from the question, you were asking about the risk of acquiring HIV from wearing a condom than may have been used three or more days prior by a person with HIV.

This scenario is determined to carry a negligible risk. The practices assigned this risk level present a potential for HIV transmission because they involve an exchange of bodily fluids. However, the amounts, conditions and media of exchange are such that the efficiency of HIV transmission appears to be greatly diminished. There are no confirmed reports of infection from these activities.

As for your specific question about dried blood coming into contact with your urethra, consider the following: "To obtain data on the survival of HIV, laboratory studies have required the use of artificially high concentrations of laboratory-grown virus. CDC studies have shown that drying of even these high concentrations of HIV reduces the amount of infectious virus by 90 to 99 percent within several hours. Since the HIV concentrations used in laboratory studies are much higher than those actually found in blood or other specimens, drying of HIV infected human blood or other body fluids reduces the risk of environmental transmission to that which has been observed - essentially zero" (2).

It is impossible to attribute the rash on your penis to an HIV infection since it could be caused by any number of other factors.

The scenario you described of someone with HIV repackaging condoms containing their own blood or ejaculate, and distributing them on the internet is unlikely, however, even if these circumstances did exist your risk of acquiring HIV would be extremely remote.

Recommendation: There are no evidence or no documented cases of transmission. You may want to refer to your physician regarding your penis rash.
