Newswise — Spring has arrived. The new season is bringing budding trees and blossoming flowers, along with runny and stuffy noses, sneezes and itchy, watery eyes.

Nearly 1 in 5 children have a seasonal allergy, according to the U.S. Centers for Disease Control and Prevention. Allergies can happen when a person’s immune system overreacts to a substance. Pollen from trees, grass or weeds is the culprit of most seasonal allergies.

Jennifer Dantzer, M.D., pediatric allergist, and Robert Wood, M.D., director of pediatric allergy, immunology and rheumatology, both at Johns Hopkins Children’s Center, are available to discuss topics related to springtime allergies, including:

  • How seasonal allergies develop
  • How climate change can affect seasonal allergies
  • The allergy season timeline for your region
  • The difference between allergies, colds and other respiratory viruses
  • Why some children are affected by allergies and others are not
  • Helpful tips to deal with children’s allergies
  • When to see an allergist and get allergy testing

Depending on the region of the U.S., spring allergy season can last until the early summer.
