Answer

Answer

Both outdoor and indoor aeroallergens sensitize and exacerbate allergic asthma, and more than 90% of the average person's time in developed countries is spent indoors. Major indoor aeroallergens are derived from dust mites (see the image below), cockroaches, cat, dog, and other furry-animal debris, and fungi.
