Reye's syndrome in Denmark. A retrospective study.
We tried to determine the incidence of Reye's syndrome (RS) in Denmark in a retrospective study. As RS is often preceded by influenza B, we chose the year 1979, where an epidemic of influenza B was registered in Denmark. All children aged 1 month to 18 years, who died, were identified, excluding children who died from accidents or malignant diseases. Two hundred and forty-two children died in hospital. Review of the records revealed one case of RS. One hundred and five died outside hospital. Reviewing death certificates and autopsy reports, none of these fulfilled the criteria for RS. All paediatric departments were asked if they had made a diagnosis of RS. None had. In 1979 approximately 1.1 mill. children aged 1 month to 14 years lived in Denmark. This gives an incidence of 0.09 per 100 000 for 1979. Although this is a minimum figure, the incidence of RS in Denmark, for unknown reasons, seems very low.
