Wookiee flu was an illness that caused the afflicted individual to experience vomiting and increased mucus production at a level comparable to the Wookiee species. When the human Chelli Lona Aphra was an archaeology student at the University of Bar'leth between 11 BBY and 3 BBY, her lover Yoshi became sick with Wookiee flu soon after their first encounter. Aphra found the symptoms too disgusting to be around Yoshi any longer. After starting a new relationship with fellow university student Sana Starros, Aphra gave her a brief description of Yoshi's symptoms and advised her to avoid picturing it.
In 0 ABY, Aphra created a recording for Starros that she intended her to hear after her death. During the recording, Aphra recounted a number of events in her life, including when she told Starros about Yoshi coming down with Wookiee flu.
