The economic burden of varicella among children in France: a caregiver survey

• We conducted an online survey of caregivers of 185 French children (≤17 years) diagnosed with varicella and collected data on varicella-related healthcare resource use, missed school days and workdays. Our study estimated annual societal burden of pediatric varicella in France. Out of 185 children with varicella, most (95.1%) had at least one outpatient visit, 10.3% had at least one emergency room visit, and 2.2% were hospitalized. 61.1% of parents with sick child, missed work and median productivity loss was 2.0 workdays. Additionally, 170 children who attended school or preschool missed a median of 5.0 school days. • The societal burden of pediatric varicella in France was estimated to be €450,427,578 (95% CI, €357,144,618 - €543,710,538), with indirect costs accounting for 85%. Pediatric varicella is associated with a substantial economic burden in France, primarily due to high productivity losses among parents and caregivers.
