Nothing to sneeze about

Scientists at the National Institute of Environmental Health Sciences and the U.S. Department of Housing and Urban Development have found that dog and cat allergens are universally present in U.S. homes. Although allergen levels were considerably higher in homes with an indoor pet, levels previously associated with an increased risk of allergic reactions were common even in homes without pets.

Interestingly, the researchers found that dog and cat allergen levels were higher among households located in communities where dog or cat ownership was more prevalent, regardless of whether or not the household had a pet.

Because allergens can be transported on clothing, the researchers speculated that the community may be an important source of these pet allergens. If you're allergic to dogs or cats and your community has a high pet population, you may find them difficult to avoid. Frequently dusting and vacuuming will help reduce the allergens in your home.
