- To describe the current panorama of severe chickenpox disease and seroprevalence in Sweden, as a basis for the approaching decision on universal vaccination.We included patients discharged with an International Classification of Diseases, 10th revision-code for chickenpox (B01.1-9) in eight pediatric and infectious diseases departments in Stockholm and Gothenburg in 2012-2014 and reviewed their medical charts. Further, residual serum samples collected from 16 laboratories across Sweden were analyzed for varicella zoster IgG-antibodies to investigate the age-specific seroprevalences.In all, 218 children and 46 adults were included in the hospital-based study, 87.2% of children and 63.0% of adults had complications. An underlying condition was not associated with an increased risk for complication. In children dehydration (31.7%), bacterial skin infections (29.8%) and neurological involvement (20.6%) were most frequent complications. Among adult cases, 63 % were born abroad. The seroepidemiological analysis included 957 patient samples. Seroprevalence was 66.7% at 5 years and 91.5% at 12 years. Infants and adolescents/adults were overrepresented among admitted patients compared to seroprevalence data.Half of all complications in hospitalized chickenpox cases was seen in previously healthy children, which supports universal childhood vaccination. Adult migrants was a risk group for chickenpox hospitalization. Age-specific seroprevalence was similar to neighboring countries.
