title: The seasonal variation of allergic respiratory symptoms induced by house dust mites.
abstract: Patients who had a positive prick test only to house dust mites either had aggravation of respiratory symptoms in the colder months when mites had died and had disintegrated to dust or had no seasonal change in symptoms; none had worsening of symptoms in the summer when the number of intact mites was highest.
