The literary record presents an entirely different medical outcome. In 1995, author Winston Groom published Gump and Co., the official book sequel to his 1986 novel. Groom directly addressed Jenny's death on the page, explicitly naming Hepatitis C as the cause.
The divergence makes epidemiological sense. Hepatitis C was officially isolated and identified by researchers in 1989, meaning that throughout the 1970s and 1980s, patients suffering from it were simply classified as having "Non-A, Non-B Hepatitis." Because Hepatitis C spreads rapidly through intravenous drug use and blood contact, Jenny's lifestyle during her rock-and-roll years made her vulnerable to both pathogens. Groom preferred Hepatitis C because he felt it fit the exact timeline of liver failure without dragging Forrest and his son into the specific social panic surrounding HIV transmission.
