What this video covers
The clip separates two things that get used interchangeably.
A mold allergy is an immune reaction to spores, producing sneezing, itching and watery eyes. It behaves like other allergies, appearing on exposure and settling afterwards. Mold illness is described as a different mechanism with a different symptom profile.
