Allergies

The prevalence of allergies has risen significantly since the late 20th century. There are many types of allergies; the most common are allergies to pollen, dust mites, mold, food, medication, insect stings, latex, and animal dander. Estimates of the prevalence of allergies among the population differ widely depending on age and type of allergy. From 1997 to 2011, the prevalence of food allergies in children increased by 50%. An estimated 8% of children and 3% to 4% of adults have food allergies. Research continues to explore a potential cure for allergies.
