Her brother’s friend is an AIDS victim.

in rewriting this sentence so it would not be Talking about People with Disabilities and Diseases. would I just say her brother's friend is a victim and leave out the word aids.

I think it would be better to say something like this --

Her brother's friend has AIDS. This is a statement of fact. I think we want to avoid using the term "victim" when referring to a person with disabilities.

Thank you I understand know.

You're welcome. :-)
