Can You Be Allergic To Black Mold

Clinical Relevance Of Allergenic Fungi

Allergy Advice : How to Stop Itching From Mold Allergies

Several fungal species cause allergic reactions in humans. The most common and best described mold allergen sources belong to the taxonomic group fungi imperfecti , which includes Alternaria, Cephalosporium, and Aspergillus species. Species of Basidiomycetes and yeast, such as Candidiasis albicans, are also important allergen sources.

Alternaria and Cladosporium species are common in outdoor environments worldwide. Airborne spores and mycelium debris of Cladosporium and Alternaria species are present during spring, summer, and especially autumn because of the degradation of leaves and other biomaterial. In indoor environments, Aspergillus and Penicillium species predominate with relatively few characteristic seasonal changes.

In early 1970, the United States faced an unexpected energy crisis because of the political climate in the world. The heavy dependence on foreign oil suddenly became a national issue. In responding to the call for conservation, the housing industry used more energy-saving insulation in buildings. However, the heavy insulation unexpectedly resulted in an excessive increase of humidity inside those buildings. This led to increase in mold-related health issues because the increased humidity led to higher mold counts within the buildings.

How To Minimize Molds Effects

The United States Environmental Protection Agency states that there are a number of precautions to take to ensure youre as safe as possible when youre in a mold, damp environment. These include:

  • Always wearing personal protective equipment. Whenever you could be potentially exposed to mold, always protect yourself out with protective gloves, an N-95 respirator and goggles.

  • Avoiding potential fires and carbon monoxide poisoning. Always use portable generators with care, away and outside of your home.

  • Making sure there are no more traces of mold. You need to ensure theres no more mold before you go back to your home to live.

You can also do the following to guard against mold growing in your home:

  • Keep it well ventilated.

  • Clean mold from hard surfaces with water and detergent. Then, dry the area thoroughly.

  • Clean refrigerator drip pans regularly.

  • Clean garbage cans regularly.

  • Clean any leaks or spills in a timely manner.

  • Open windows, use exhaust fans or dehumidifiers to keep moisture to a minimum.

  • Ensure the outside of your home benefits from adequate drainage.

With the recent floods, many Texans may find patches of mold growing in their homes. As you can see from the above, molds do have the potential to cause health issues. But, dont panic. Theres plenty that you can do about mold growing in your home and about mold allergies.

What Does Black Mold Exposure Treatment Look Like

Just like the diagnosis, the treatment of mold exposure differs from doctor to doctor. One thing most doctors will advise you to do is to test for and, if needed, remove any unhealthy mold conditions from your home. Even if the treatment will help in the short-term, it wont be effective over the long-term if your indoor environment isnt improved.

To treat the symptoms, doctors may suggest:

  • Over-the-counter medication. Medicine that would decrease the airway inflammation and suppress the allergic reactions.
  • Nasal sprays to deal with a runny or stuffy nose or rinses to clear your nasal passages from inhaled mold spores.
  • Regular allergy medicine

A persons immune system must be working properly to fight mold symptoms, so changes in a lifestyle or diet might be necessary. In more severe allergy cases, doctors prescribe immunotherapy to relieve symptoms

What Happens When You Inhale Black Mold Spores

We live in a moldy world. Like it or not, mold is all around us, both outside and inside. Mold spores exist in practically every indoor environment, and according to the Environmental Protection Agency , eliminating them from indoors completely is impossible.

Like many other fungi and plants, mold spreads by producing spores that travel on the air. Everyone encounters mold spores, and the vast majority of time, they dont trigger adverse health effects. However, it depends on the type of mold spore.

Researchers have long established that Stachybotrys chartarum, commonly called black mold, is capable of harming human health. However, the specific effects of breathing black mold spores depend on several factors, including what those spores carry. If youre concerned about how breathing black mold might affect you, keep reading.

Mold Around The House

While antihistamines can address many of the symptoms of a mold allergy, they are often not a sufficient standalone response to mold. Antihistamines can have sedating effects on users and adversely interact with other prescription and over-the-counter medications, so it is best not to rely on them entirely. Instead, after identifying signs and symptoms of a mold allergy, work to reduce the presence of mold in your home. This process often involves optimizing air filtration systems, cleaning bathrooms regularly, and making basement living spaces as hypoallergenic as possible by limiting porous surfaces, such as carpeting, where moisture and attendant mold can build up. While it is impossible to eliminate mold exposure, especially outdoors, you can significantly mitigate mold exposure within the home.

How To Get Rid Of Mold In Your Home

Mold should be removed as quickly as possible.

To clean mold off hard surfaces, such as tile, scrub with soap and water, commercial products, or use bleach. To make a bleach solution, mix 1 cup of bleach to 1 gallon of water. When cleaning with bleach, be sure to protect your skin and eyes, and allow for plenty of ventilation.

You may not be able to save porous or absorbent materials such as drywall, ceiling tiles, and carpeting. Once theyve become soaked or are growing mold, they generally need to be removed and replaced.

For big mold problems, consider hiring a professional cleaning company experienced in removing mold. If its not completely cleaned, it can start growing again. For that reason, its important to fix the source of the problem as well.

If your home has a lot of mold and you have health concerns, ask your doctor if you should stay away until the situation is remedied.

How Can I Prevent Mold Allergy

While you cant prevent mold allergy from happening, you can take steps to prevent and remove mold.

To keep mold out of your house, you need to control moisture. Take steps to keep the humidity in your house low. Make sure your house is properly ventilated. Repair any water leaks immediately.

If you have mold, you need to clean it up. You can use the appropriate household cleaners or a bleach and water solution of 1 cup bleach and 1 gallon of water. If you do your own mold cleaning, its best to wear protective clothing, including gloves and a respirator.

Some mold problems require professional help. These include situations that involve water dirtied by sewage or other contaminants. If you have severe reactions to mold, you shouldnt do your own cleaning. Its best to have someone else do the cleaning in this case.

You should throw away any carpets, rugs or other textiles that got wet and werent dried right away. Other absorbent items, such as ceiling tiles, also cant be completely cleaned of mold.

Mold isnt just an indoor problem. Outdoor mold can also present problems. If mold counts are high, it might be best to stay indoors. Try to keep your yard free of piles of damp and decaying leaves or wood. Check your local mold counts to determine if air quality is safe.

Determinants Of Allergic Fungi

9 Signs You Have Toxic Mold In Your Home

The cross-reactivity of allergens derived from common airborne fungus spores remains controversial. Allergenic cross-reactivity such as observed between Phoma and Alternaria extracts more likely reflect the presence of shared epitopes in the species’ reproductive stages. Establishing biologic or allergenic properties among molds is difficult, especially imperfect fungi. Therefore, defining Ag determinants is important when a mold allergen extract is prepared.

Total airborne fungi in North America range from extremely low levels during periods of below-freezing temperature to peak levels that usually occur in late summer and early autumn. This pattern parallels variations in dominant Cladosporium and Alternaria species in many areas. Penicillium species most often lack a defined annual pattern A fumigatus may be more prominent from December-April in some areas but can be unpredictable in other regions. Mold allergy may account for persistent respiratory symptoms in individuals during nonpollen seasons.

Poorly maintained cold-mist vaporizers and some console humidifiers can emit dense microbial aerosols during operation. If high relative humidity and condensation persist in indoor environments, mold is likely to recur after decontamination.

What Causes Black Mold

Molds are an important part of our environment. They decompose dead plants and animals. All types of mold will grow if the conditions are right. Mold grows and spreads quickly in the right conditions, which include:

  • Moisture level at or over 70%
  • Adequate food source
  • Temperatures that range from 40 to 100 degrees F

Mold can grow anywhere in your house that provides these conditions. The most likely places mold will grow are:

  • Anywhere that there has been a water leak.
  • Damp rooms without adequate ventilation, such as bathrooms.
  • Basements where humidity tends to be higher.
  • Any areas with a lot of water condensation.
  • Any areas where flooding has occurred.

Preventing Mold In Your Home

The best way to keep your family safe from black mold is to prevent it from growing. Since mold grows in damp, dark places, you should aim to improve ventilation and reduce humidity in areas that are prone to mold.

In your bathrooms, for example, you can use a shower squeegee to remove excess water from shower walls and bathroom mirrors. You can also install a vent fan or open a window when showering to allow humidity to leave the room. These steps help reduce the moisture in your bathroom and make it more difficult for black mold to grow.

Make searching for black mold or potential growth areas a part of your spring cleaning routine. The sooner you catch a mold growth, the better chance you have to get rid of it before it causes health problems.

  • You previously tried removing mold yourself

Take note of how you feel in and out of the house. If the symptoms disappear or decrease when youre out and about, then you might have a mold problem, yes, even if you cant see mold.

What Are Microbial Volatile Organic Compounds

ALLERGY HELP AFTER MOLD EXPOSURE

Another source of irritation from mold exposure comes from substances knownas microbial volatile organic compounds . These compounds are producedthrough fungal metabolism and are released directly into the air, often givingoff strong or unpleasant odors. Exposure to mVOCs from molds can irritate theeyes and respiratory system and has been linked to symptoms such as headaches,dizziness, fatigue, nasal irritation and nausea. The effects of mVOCs are notcompletely understood and research is still in the early stages.

Immunologic Evolution Of Allergy

Allergen-specific IgE produced by B cells mediate allergic diseases. The allergen sensitization begins with the processing of mold Ags by Ag-presenting cells , such as dendritic cells. APCs present processed mold allergens to naive T-helper cells, which differentiate into the effector stage type 2 Th cells and produce Th2 cytokines . IL-4 is essential for isotype switching to IgE and with additional signaling provided by the Th2 cells, B cells begin to produce IgE specific for allergens.

The Fc portion of IgE antibody binds to high-affinity Fc receptors expressed on the cell surface of mast cells in tissue, which, in turn, stabilizes Fc. IgE bound to FcR is stable for several weeks. When allergens bind to adjacent 2 IgE molecules bound to FcR , an activation signal is elicited, leading to the release of preformed and newly formed mediators from mast cells .

These mediators include histamine, leukotrienes, and prostaglandins, which cause acute tissue inflammation. Mast-cell activation also lead to release of various chemotactic factors, such as leukotriene B4, platelet-activating factor, and eosinophil chemotactic factor, resulting in an influx of eosinophils, neutrophils, and mononuclear cells into the site of mast-cell activation. Mast cells also produce IL-4, IL-5, and IL-13, further augmenting Th2 responses and IgE production.

Myths About Black Mold

Black Mold – How To Kill Toxic Mold In Under 5 Mins!

Its important to address myths some people may have about black mold. One common rumor is that black mold releases toxic compounds called mycotoxins that cause health issues, like memory loss, headaches, and infant pulmonary hemorrhage.

But according to a review from 2017, theres no evidence that exposure to black mold causes particular health conditions.

Furthermore, while a variety of molds produce mycotoxins, these compounds are primarily dangerous for humans only when eaten in significant quantities.

A 2019 review of research into this topic states theres currently no evidence that mycotoxins in the air cause disease.

How Common Is Mold In Buildings

Molds are very common in buildings and homes. Mold will grow in places with a lot of moisture, such as around leaks in roofs, windows, or pipes, or where there has been flooding. Mold grows well on paper products, cardboard, ceiling tiles, and wood products. Mold can also grow in dust, paints, wallpaper, insulation, drywall, carpet, fabric, and upholstery.

The most common indoor molds are Cladosporium, Penicillium, and Aspergillus. We do not have precise information about how often different molds are found in buildings and homes.
