Study by NIEHS on dog and cat allergens in homes in Journal of Allergy and Clinical Immunology (July 2004)

“Study by NIEHS on dog and cat allergens in homes with and without these pets, in Journal of Allergy and Clinical Immunology (July 2004) Exposures in homes and schools to dog and cat allergen have been shown to contribute to the prevalence and severity of asthma attacks, and, based on research to date, their role in causing asthma has been the subject of debate. Scientists at the National Institute of Environmental Health Sciences and the U.S. Department of Housing and Urban Development found detectable levels of cat and dog allergen in every U.S. home studied. The NIEHS press release stated, Although allergen levels were considerably higher in homes with an indoor dog or cat, levels previously associated with an increased risk of allergic sensitization were common even in homes without the pets.”” They analyzed dust samples and asked questions in the first, nationally representative sample of homes, The National Survey of Lead and Allergens in Housing. The 831 homes were sampled from seventy-five randomly selected areas– generally counties or groups of counties– across regions of the country (northeast, southeast, midwest, southwest, northwest), housing types, and settings (urban, suburban, rural).
