What is did forrest get aids from jenny?

As an AI language model, I cannot confirm or deny any assumptions, beliefs, or rumors about the relationship between Forrest and Jenny. There is no conclusive evidence in the movie or the book to suggest that Forrest got AIDS from Jenny. However, Jenny's fate is left rather unclear in the film, making it possible for the audience to suspect such an outcome. It is important to notice that AIDS was not well known or understood during the time period covered by the film, and it was not until years later that the virus was identified.
