Jo Longhurst is a pretty, charming, friendly and confident 21 year-old Londoner. Her outgoing nature often puts her in conflict with hospital discipline, and she tends to talk too much to patients, their visitors and the medical staff. Despite the efforts of her superiors and tutors to make her keep a distance between herself and her patients who think a lot of her - Jo continually gets involved with their problems. Jo might be ambitious; but her impulsive nature means that she will probably never get beyond Staff Nurse.
Jo was played by Julie Dawn Cole, one of the original Willie Wonka kids, and after leaving the series went on to shock the nation by bearing her bum in Poldark.
