My friend is in South Africa on business. Before going home, he played ball with a black man. His arm was accidentally cut and the black man's nose was bleeding. He is afraid of contracting HIV. Urgent! You really don't have to worry about HIV infection.

1. Don't think that all black people have AIDS. As long as they are not in high-risk areas, the HIV-carrying rate of blacks is similar to that of people in other places.

This is unprecedented all over the world. It can only be said that in theory, this possibility cannot be ruled out: only when a black man has AIDS and the blood in his nose flows into your friend's fresh wound at that time can he be infected with HIV. Otherwise, it is impossible. I believe he won't be infected, because the probability is almost negligible.

You can wait for 6 weeks to have a check-up, because you are afraid. Generally speaking, the post-exposure prevention (PEP) of HIV should be carried out within 72 hours, and the success rate can be guaranteed. It's useless if it's late. Your situation doesn't need to be done, because it is only necessary to determine the source of infection and establish the route of infection, and your worry is unnecessary.
