title: Adenovirus type 19 keratoconjunctivitis in Canada.
abstract: We describe an outbreak of epidemic keratoconjunctivitis occurring in Montreal during the winter of 1974. Adenovirus type 19 was the only virus isolated. We confirm the presence of type 19 adenovirus in Canada; it produces severe keratoconjunctivitis. The incubation period, method of spread and clinical findings resemble those seen in outbreaks of type 8 EKC. The prevalence of adenovirus type 19 in the population of Canada is unknown. Although some object to the use of the term EKC for infection caused by adenoviruses other than type 8, we believe that EKC should be regarded as an entity requiring virus isolation and antibody determination to identify the adenovirus type responsible for it.
