La urticaria es una reacción alérgica que causa parches de piel enrojecidos, hinchados y con picazón que aparecen en un área del cuerpo o en todo el cuerpo. Generalmente, la reacción es a un alérgeno como alimentos o medicamentos. Los alimentos que comúnmente causan urticaria en los niños incluyen nueces, huevos y leche. Las picaduras de insectos, las infecciones virales y la exposición al sol también pueden ser desencadenantes, pero algunas ronchas aparecen y desaparecen sin una causa conocida.
