Molds

Molds are microscopic fungi, like mushrooms, but without stems, roots or leaves. Their spores float in the air like pollen and are present throughout the year in many states. Common airborne molds include alternaria, cladosporium and aspergillus. Molds do not have a specific season, but are affected by weather conditions such as wind, rain or temperature.

Outdoor molds can be found in soil, vegetation and rotting wood. Spores begin to appear after a spring thaw and reach their peak in July in warmer states and October in the colder states. Molds can be found all year long outdoors in the South and on the West coast.

Indoor molds and mildew thrive in areas of the house with increased humidity, such as damp basements and bathrooms. They can also be found in attics, refrigerators, food storage areas, garbage containers, carpets and upholstery. These molds send out small spores that can trigger allergy symptoms.

Mold Allergy Symptoms
The symptoms of mold allergy show up primarily in the respiratory tract, with nasal symptoms and chest symptoms in some cases. Common symptoms include:

• Sneezing

• Nasal congestion

• Clear runny nose

• Itchy watery eyes

Mold allergies can also trigger asthma, with symptoms of wheezing, cough and shortness of breath. Mold allergy is best diagnosed through skin testing by an Allergist/Immunologist. When skin testing is not able to be done, blood tests may help with the diagnosis of mold allergy.

Mold avoidance
Typical outdoor situations where mold allergy may be triggered include:

• Being near heavy vegetation

• Being near hay and straw

• Raking leaves

• Cutting grass

• Going outside after a rainstorm


Indoor mold avoidance and control measures include:

• Wearing a filter mask if exposure is anticipated

• Eliminate any source of excess dampness in basements

• Consider a dehumidifier

• Try to keep indoor humidity levels between 40% and 50%

• Change heating and air conditioning filters regularly

• Make sure there is adequate air circulation and ventilation

• Clean washable surfaces with a bleach solution

It's best to contact an Allergist/Immunologist if you are having symptoms and think they may be coming from mold exposure.
