An outbreak of viral gastroenteritis in a psychiatric hospital

Abstract In September and October 1987, an outbreak of gastroenteritis due to small round structured viruses occurred in a large psychiatric hospital. A total of 149 people, 83 patients and 66 members of staff, were affected over a 26-day period. Most cases were associated with three psychogeriatric wards. The outbreak highlighted the special problems of infection control in long-stay psychiatric units and methods of overcoming these difficulties are discussed.
