Alternaria Tenuis Sensitivity: Causes, Symptoms & Treatment Options

Alternaria Mold Allergies in Scottsdale, Arizona

Experiencing sudden allergy symptoms after a summer storm or fall hike? The cause may be Alternaria tenuis, a common mold found on decaying leaves and organic matter. While natural and widespread across North America, its airborne spores can trigger allergies in sensitive individuals.

When Allergies Occur
Alternaria spores peak in late summer and early fall (August–October). Outdoor activities like raking or mowing can stir up spores and worsen symptoms.

Common Symptoms

  • Runny or stuffy nose

  • Itchy, watery eyes

  • Sneezing and coughing

  • Scratchy throat or postnasal drip

  • Headaches or facial swelling (severe cases)

  • Difficulty breathing (severe cases)

Prevention Tips

  • Track mold spore counts and limit outdoor exposure

  • Keep windows closed and use HEPA air purifiers

  • Shower and change clothes after being outside

  • Reduce indoor moisture with dehumidifiers

  • Avoid disturbing decaying leaves or compost piles

Who’s at Risk?
People with a family history of allergies, hay fever, asthma, or exposure to damp environments are more likely to develop Alternaria sensitivity.

Treatment Options

  • Over-the-counter antihistamines and decongestants

  • Prescription nasal corticosteroids

  • Allergy shots (immunotherapy) to reduce sensitivity over time
