UNLABELLED: The absolute number and the rate of allergic diseases among the population are increasing worldwide. The sequence of the allergens can change during the years even in the same area. METHODS: The authors examined the results of skin prick tests of 2124 children between the age of 3 and 18 suffering from respiratory diseases caused by allergy between 1992 and 2000. RESULTS: According to their results, in each year the number of boys was double of the number of girls, most of the patients were sensitive to grass pollen (32.8%), 27.6% was allergic to ragweed pollen, 22% to tree pollen. The prevalence of mould allergy increased by the years. 37.9% of the patients allergic to indoor allergens were sensitive to animals, the most frequent among them was cat allergy. The rate of house dust mite allergy was 27.8% and 25.2%. CONCLUSIONS: The authors' findings are similar to those of other investigators.
