Andersson et al. 2003. Investigators studied a group of 132 children during the years 1998/99. Skin prick tests were used to identify specific sensitivities, questionnaires were completed by subjects' parents, and a spore trap was used to monitor outdoor air. Authors found that nocturnal nose symptoms and eye symptoms were significantly associated with Alternaria concentrations in Alternaria-sensitive children.
