Children with atopic eczema experiencing increased disease severity in the pollen season more often have hay fever at a young age and a dark skin type.

Children with atopic eczema are known to experience seasonal variations in disease severity, with winter being the season in which severity generally increases. There is a lack of knowledge about the subgroup of children that experiences increased severity in spring and summer months. We aimed to investigate which phenotype characteristics best describe children flaring in the pollen season.
