In the movie Forrest Gump, Jenny dies after contracting "some kind of viris" in the 1980s. Though never said specificly it can be heavily implied from Jenny's drug using and promiscuous lifestyle in the 60s and 70s could've led her to contracting HIV/AIDS.
When the film came out, my sister thought that, too. That Jenny had contracted AIDS.
However, that makes no sense historically. If Jenny had been a junkie in the mid-80s, then I suppose it's possible. But she wouldn't have picked HIV up through sexual contact during the 1960s -- while the AIDS virus had come to the United States sometime around 1969, it was confined to the homosexual population, and at late as 1982 it was still confined to that population, with a total outbreak in the mid-hundreds. It certainly wasn't a heterosexual disease at that point.
So, if the movie tried to imply that Jenny was an early AIDS victim, the movie is wrong.
It could be the cervical cancer virus that Jenny picked up. That would make sense.
In no way does HIV make sense.
