We have investigated the prevalence of allergens from cat, dog, house dust mite, pollen, mould and food in dust samples from schools and homes in Norway. Occurrence of cat and dog allergens in schools was surprisingly high, especially in classrooms with carpeted floors. Cat and dog-derived allergens are brought into schools through the pupils' outside contact with pets. Children who are in contact with pets at home or in their surroundings carry animal hair and dander into the classrooms on their clothes, shoes and bags. The schools seemed to be a protective environment against mite infestation, as verified by very low content of mites in both carpeted and smooth floors. Furthermore, while cat and dog allergens were more prevalent in schools than in homes without pets, mite and food allergens were more dominant in homes. Frequent cleaning is important in schools, to prevent accumulation of animal hair and dander in the classrooms. We emphasize the obvious advantages of linoleum floors over carpets in decreasing the pupils' level of exposure to indoor allergens and dust.
我们调查了挪威学校和家庭灰尘样本中猫、狗、屋尘螨、花粉、霉菌和食物过敏原的流行情况。学校中猫和狗过敏原的出现率高得出奇，尤其是在铺有地毯的教室。猫和狗源性过敏原通过学生在户外与宠物接触而被带入学校。在家中或周围环境中接触宠物的儿童会将动物毛发和皮屑带到教室，沾在衣服、鞋子和书包上。学校似乎是一个防止螨虫滋生的保护环境，这一点在铺有地毯的地板和平滑地板上螨虫含量极低得到了证实。此外，虽然有宠物的学校中猫和狗过敏原比无宠物家庭中更普遍，但螨虫和食物过敏原在家庭中更占主导地位。学校经常清洁很重要，以防止教室中动物毛发和皮屑的积累。我们强调油毡地板相对于地毯在降低学生接触室内过敏原和灰尘水平方面的明显优势。
