This is a risk assessment forum. However, what can I tell is that I doubt that TB has anything to do with HIV as it appears in a very progress state of the disease. If this girl is healthy 6 years after treating TB, I doubt it is related. However, I think the girl should be tested for HIV and others STD link to the assault.
are there chances of hiv even after 10 years when both of them are healthy and the boy was really young when he did that
furthermore she has not any std as far as i know
