About 50 million people in the United States suffer from some form of allergy and asthma. The most common allergies are to dust, mildew, milk, food, nuts, latex, insects (especially bee stings), animal dander, pollen, tobacco smoke, aerosols, paint, perfumes, cleaning products or other strong odours or fumes. Some allergies are seasonal, such as an allergy to ragweed pollen. Other allergies extend throughout the year. Children whose parents suffer from allergies are 70% more likely to have the same allergies than children who have parents without allergies.
