H James Wedner, MD interviewed by TIME about seasonal allergies

Millions of Americans spend weeks each year sneezing and sniffling due to allergies to seasonal triggers such as tree, grass, or ragweed pollen. And for the subset of people who are allergic to year-round household irritants like dust mites, mold, and cockroaches, any season can turn into allergy season. …The severity of symptoms and the difficulty of treating them can vary depending on your genes, how many substances you’re allergic to, and your level of exposure, says Dr. H. James Wedner, an allergy and immunology specialist at Washington University in St. Louis.
