Official agencies will tell you that there is some risk for HIV from cutting your knuckles during a fight with a bleeding person with HIV, the risk is theoretical and to my knowledge there are not cases in which persons have acquired HIV in the way you describe. Nonetheless, I am sure that at least some experts would suggest PEP if it has been less than 72 hours since the fight. Since it has been two weeks however, the best thing to do is to test for HIV using either a combination HIV p24 antigen/HIV antibody test at 4weeks after the fight or a standard HIV antibody test at 8 weeks. When you test, I predict that your test will be negative.
I hope this information is helpful. EWH
At 25 days a standard HIV antibody test will detect close to 90% of recent infections. Antibody test provide definitive results at 8 weeks. EWH
Dear Dr.
I did a test for HIV at 25days after the fight. It is negative.
Is it means that I don't have to do any other tests?
Thanks again for your help.
As I said above, it would be appropriate for you to be tested but I would not worry. EWH
Thank you doctor.
So I can relax now?
No, there is not a numerical risk that can be assigned. EWH
Thank you doctor.
Some Chinese experts said it is high risk, I'm very worried about that.
In the theoretical risk, is it has a exact probability value.
Your help is appreciated.
