Expo '86, Vancouver: impact on British Columbia's Children's Hospital.

Over 22 million visitors attended the 1986 world exposition in Vancouver, and this had a significant impact on the local pediatric facility. A total of 559 children visited the emergency department of British Columbia's Children's Hospital with injuries or illnesses resulting from the fair. Of these, 193 (34%) had come directly from the site. The children's ages ranged from 1 1/2 months to 18 years, 4 months (mean 6.99 years). Of the 559 children 31% were not covered by medical insurance. Twenty-four of the children were admitted to the hospital, and one died at the Expo site. Most of the illnesses were upper respiratory tract infections and gastroenteritis. The proportion of visits for trauma was 50%, compared with the yearly average of 25%. There was a 6% increase in the workload in the emergency department during the fair; the percentage was even higher during July and August, particularly after 1800 hours. Recommendations are made to aid with the planning of medical care for similar events.
