Dog and Cat Allergens
Believe it or not, there is a significant amount of dog and cat allergen present in areas where there has never been a dog or cat, especially at schools. Carpeting and upholstered furniture has the highest levels of pet allergens, enough to cause allergy and asthma symptoms in children who are allergic. Dog and cat allergens are carried on the clothing and hair of children who have these pets at home – and the more children in the classroom that are pet owners, the higher the level of pet allergen that can be found within the classroom.Learn about avoidance of dog and cat allergy.
Dust Mite Allergens
Dust mite allergens do not appear to be present in any significant level in schools, and actually may be slightly lower than in levels found in homes. When found in schools, carpets, upholstered furniture, as well as stuffed animals seem to have the highest levels of dust mite allergen. Because dust mite is a large, heavy particle, it isn’t typically airborne in the classroom, except when there is a lot of physical activity, when it can be found in high levels in the air, enough so that children with dust mite allergy can have worsening symptoms.Learn about avoidance of dust mite allergens.
Cockroach and Rodent Allergens
Generally speaking, cockroach and rodent allergens are only found in school classrooms in areas that serve low-income and inner-city areas, as well as rural areas. The highest levels of cockroach and rodent allergens are found where food is kept and served, such as the cafeteria and kitchens. Higher levels are found in non-carpeted areas, as well as in the air. Children with allergies to cockroach and rodent allergens may certainly have worsening asthma and allergy symptoms at school.Learn about avoidance of cockroach allergen.
Mold Allergens
Mold allergens can be present in schools and classrooms, and is often airborne. The mold in classrooms can be due to outdoor sources or indoor contamination from water damage, standing water, or indoor houseplants. The presence of mold in schools can certainly worsen allergies and asthma in susceptible children.Learn about avoidance of mold allergens.
