Alternaria alternata is a fungus that releases spores into the air, triggering allergic reactions. It grows on various plants and materials, thriving in warm, moist environments. Individuals sensitive to this fungus may experience symptoms during dry, windy conditions when spore concentrations are at their peak.
Testing for Alternaria alternata allergy is recommended if you have allergic reactions during warm, windy conditions or after exposure to decaying vegetation and compost.
Alternaria alternata spores can be inhaled and trigger an immune response in sensitive individuals, leading to allergic symptoms.
Limit outdoor activities on windy days, use high-efficiency particulate air (HEPA) filters indoors, and remove decaying plants from around your home.
