Jessie was a young girl recruited to be one of the Auxiliary Animorphs.
The Auxiliary Animorphs
When the Animorphs began looking for new members, Jessie was one of the recruits selected by James. Her disease, condition or reason for being in the children's hospital is unknown, but she was not healed by the morphing process.
Jessie and most, if not all, of the Auxiliary Animorphs died in the final battle against the Yeerks' Pool ship. They had sacrificed their lives to assist Sam Doubleday's ground force as the original Animorphs invaded the Pool ship. Jake heard Visser One gleefully order the Pool ship's gunners to kill any animals in the fight below, until the gunners report none are left.
