The article does in fact say 100% of the households have detectable levels of dander. However, the concentrations of an allergen required to cause a reaction vary greatly by individual. Animal dander is easily spread and for those poor souls that have those allergies the symptoms are anywhere from upper and lower respiratory tracts which include congestion, sneezing, runny nose, chest tightness, wheezing, itching, and watery eyes.
Dander remains suspended in the air for a long time and they easily stick to surfaces.
