Mold Allergy Quiz

Concern about mold allergy and conditions thought to be associated with exposure to mold has increased over the past 10 years. Many persons suffer from mold allergy and may be exposed to high mold spore levels both outdoors and indoors. Test your knowledge of mold allergy with these questions.

Question 1
Mold is a colloquial term for fungi.

True: Most people use the terms interchangeably. However, fungi have their own biological kingdom. While most fungi might be called mold by the general public, in fact, not all molds are fungi. Mushrooms, bracket fungi and other fleshy fungi are part of the fungal kingdom but are never called molds. Also, slime mold and water mold are two examples of molds that are not part of the fungal kingdom.

Question 2
Mold allergy is caused by the response to living and dead mold spores.

True: The human allergic response is to protein allergens found on fungi and fungal spores. The protein is there whether the fungus is dead or alive.

Question 3
Which of the following can help reduce fungal spore levels in your home?
Using a dehumidifier
Prompt repair of plumbing leaks
Exterior landscape grading to move water away from the house
Well maintained guttering and downspouts
All of the above

All of the above. Control of moisture inside your home is the key to reducing fungus.

Question 4
My parents were allergic to dogs and cats but not mold. Can I have mold allergy?

Yes. If one or more of your parents was allergic to anything, you are more likely to be allergic. However, even if neither parent was allergic to mold you could still be mold allergic.

Question 5
I can sometimes see mold spores floating through the air in my home.

False: Mold or fungal spores are microscopic which means that you can't see them without the help of a microscope or a very good magnifying glass. You can, however, see colonies of fungi with thousands of spores on the top growing on wet walls or old bread.

Question 6
The possible symptoms of mold allergy include a runny, stuffy or itchy nose; sneezing; itchy or scratchy throat; red, itchy or swollen eyelids; coughing; wheezing; and trouble breathing.

True: The symptoms for mold allergy are the same as symptoms for other airborne allergies.

Question 7
The outdoor air is always full of mold spores.

True. In most areas of the United States and Canada you can find some mold spores in the air at any time of the year. The outdoor mold spore level is lower in the winter when the air is cold and higher in the summer when the air is warm and moist. Some conditions, such as right after a snowfall, have especially low outdoor spore levels and other conditions, such as right after a rainfall in the summer, have high spore levels. On frozen ground covered in snow, fungi hide for the winter.

Question 8
If you are not allergic to mold, you don't have to worry about problems caused by molds.

False. Most problems caused by mold are related to inside mold that is unsightly and smells bad. In a moldy building wood rot fungus damage the structure eventually making it unsafe. A few environmental fungi can also be infectious in humans. However, people with normal immune systems usually do not get fungal infections.

Question 9
If I can't see mold spores in the air I can't know when they are high outside.

False. The National Allergy Bureau™ (NAB™) reports outdoor mold spore levels for many areas of the United States and Canada when outdoor mold spore levels are high enough to cause mold allergy symptoms. There is likely to be an NAB station somewhere near you.
