Can rh negative people get HIV/AIDS?

The answer is “Yes”.
I have personally spoken with both, medical professionals and rh negative (including O negative) AIDS patients and there is no connection between ABO blood groups and the rhesus factor and immunity to the HIV/AIDS virus.

Researchers have developed more sophisticated methods for typing blood in recent years. Moving beyond the old-fashioned grouping systems that split people into A, B and O blood types—and the more recent Rh blood typing system—they’ve uncovered another method for grouping people by their blood characteristics. The new method is concerned with a carbohydrate-carrying antigen called Pk. Some people have a lot of Pk in their blood, while others have none at all. Most people fall somewhere in between.

They found that the cells of people who express high levels of Pk, a rare group representing about one in a million people, were resistant to HIV infection. Conversely, the cells of those who express no Pk at all, representing about five in a million people, were particularly susceptible to HIV infection.

Individuals expressing HLA-B57 presented significantly less frequently with symptomatic acute HIV-1 infection (4/116, 3.4%) than expected from the frequency of chronically infected individuals expressing this allele (43/446, 9.6%; P < 0.05). During acute infection, virus-specific CD8 T-cell responses were dominated by HLA-B57-restricted responses, with significantly broader (P < 0.02) and stronger (P < 0.03) responses restricted by HLA-B57 than restricted by all other co-expressed HLA class I alleles combined. Six out of nine individuals expressing HLA-B57 controlled HIV-1 viremia in the absence of therapy at levels < 5000 copies/ml (median, 515 copies/ml) during up to 29 months following acute infection.

One study indicates that Rh(D) positive (97.8%) was more susceptible than D negative (2.2%). That could mean that rh positive individuals are around 7 times more likely to contract the HIV virus than rh negatives.
