To estimate the economic burden of varicella among children in France from family and societal perspectives. We conducted an online cross-sectional survey of caregivers of 185 French children (≤ 17 years) diagnosed with varicella in the previous six weeks. Data collected included varicella-related healthcare resource use, out-of-pocket costs, missed school days, and workdays missed by either parents or other caregivers. Mean and median direct and indirect costs (2022 Euros) were calculated using survey data and published literature. The annual societal burden of pediatric varicella in France was estimated. Of the 185 children, 95.1% had ≥ 1 outpatient visit, 10.3% had ≥ 1 emergency room visit, and 2.2% were hospitalized. The median [interquartile range, IQR] number of outpatient visits/child was 1.0 [1.0 – 2.0]. The median length of hospital stay among those hospitalized (n = 4) was 5.0 [3.5 – 6.5] days. Caregivers of 185 children missed a median of 2.0 [0 – 5.0] workdays; 113 families (61.1%) had ≥ 1 parent miss work. A median of 5.0 [3.0 – 7.0] school days were missed by 170 children who attended preschool or school. The median direct out-of-pocket cost to the family was €30.0 [€17.0 – €60.0]. The median [IQR] societal costs per varicella case were €455.2 [€70.5 – €1013.5]; the median [IQR] direct and indirect costs per child were €60.8 [€39.0 – €102.7] and €364.7 [€0.0 – €911.7] respectively. The annual societal burden of varicella among children in France was estimated to be €450,427,578 (95% CI: €357,144,618 – €543,710,538), with indirect costs accounting for 85%.Conclusions: A substantial economic burden is associated with pediatric varicella in France, primarily due to the productivity loss among caregivers.What is Known:• Although varicella is considered a mild disease, it poses a significant burden on caregivers and society. Our study aimed to estimate the economic burden of varicella among children in France from family and societal perspectives to support policymakers in understanding the value of UVV in France.What is New:• 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.
