Beyond CIRS
Understanding Mold-Related Illnesses

As homeowners, we strive to keep our living spaces safe and healthy. We routinely clean and maintain our homes to avoid common problems, yet one issue often goes unnoticed: mold. While mold is widely associated with allergy-like symptoms and respiratory issues, it can also contribute to more serious health concerns.
To address this broader scope, Mold Inspection Sciences (MIS) have recently expanded their chronic inflammatory response syndrome (CIRS) protocol into a more inclusive mold-related illness and CIRS program (MRIC). In this article, we’ll explore how mold illnesses extend beyond CIRS and why it’s important to take a comprehensive approach to mold exposure.

What is CIRS?
CIRS can occur when your immune system overreacts to certain toxins, including those produced by mold. Identified by Dr. Ritchie Shoemaker, CIRS—often called “biotoxin illness”—can lead to systemic inflammation, resulting in symptoms such as chronic fatigue, joint pain, and brain fog. Although CIRS is widely recognized as a serious condition, it isn’t the only mold-related health issue. In fact, many people suffering from mold-related illness may actually be affected by undiagnosed CIRS.
Other Types of Mold Illness
Mold can affect individuals differently, leading to health problems beyond CIRS, mold allergy, or mold toxicity. Personal sensitivities and overall health determine how someone might respond to mold exposure. While we are not healthcare providers and do not offer medical diagnoses, we believe it’s important to be informed about potential impacts. If you suspect mold is affecting your health, consult your medical provider.
- Asthma and Respiratory Deterioration
- What it is: Mold spores can act as a trigger for anyone with existing asthma or respiratory conditions, potentially leading to increased wheezing, shortness of breath, and coughing.
- Why it matters: Those without a formal asthma diagnosis may develop asthma-like symptoms after prolonged exposure to high mold levels.
- Hypersensitivity Pneumonitis (HP)
- What it is: An inflammatory lung condition caused by inhaling certain fungal and sometimes bacterial particles.
- Common signs: Fever, chills, dry cough, and shortness of breath that can become chronic if exposure continues.
- Why it matters: Though less common than simple mold allergies, HP can cause persistent lung inflammation if mold sources aren’t identified and addressed.
- Chronic Sinusitis — Fungal Sinusitis
- What it is: Repeated or lingering sinus infections may be tied to mold growth, especially in damp or poorly ventilated areas.
- Typical symptoms: Nasal congestion, facial pressure or pain, loss of smell, and persistent sinus infections resistant to the usual treatments.
- Why it matters: Mold-related sinusitis can significantly affect daily comfort and, if left untreated, may worsen existing respiratory conditions.
- Aspergillosis in Immunocompromised Individuals
- What it is: A collection of diseases caused by Aspergillus, a common mold in the environment.
- Who is at risk: People with compromised immune systems or chronic lung diseases.
- Why it matters: While healthy individuals typically fight off these spores, vulnerable groups can develop serious infections, including coughing, sometimes with blood, fever, and difficulty breathing.
- Fatigue and Brain Fog
- What it is: Some individuals report persistent fatigue, “foggy” thinking, or difficulty concentrating in mold-affected environments.
- Why it matters: These subtle, nonspecific symptoms can be overlooked or confused with other conditions. Identifying a possible mold connection can lead to timely inspections and mitigation.
Why These Insights Matter
Understanding that mold can affect health in multiple ways—beyond high-profile conditions like CIRS—ensures that potential warning signs are identified sooner. Addressing mold sources promptly can prevent minor irritations from escalating into more severe problems, safeguarding the health of everyone in your home or workplace. If symptoms persist or worsen, be sure to consult a healthcare professional.
- Effectively tackling mold problems should begin with a thorough, professional mold inspection. The science-based methods at MIS include:
- Thorough assessments: Using advanced equipment to help detect both visible and hidden mold, as well as identifying moisture sources and overall indoor air quality concerns.
- Accurate analysis: Delivering clear, detailed reports with photos, lab results, and expert recommendations for the way forward.
- Conflict-free guidance: As inspection-only specialists, MIS provides unbiased results with no conflict of interest.
Uncovering potential mold issues early helps homeowners and commercial clients prevent mold-related illnesses, whether they involve CIRS or other concerns, thereby protecting the well-being of those who matter.

Take Action for a Healthier Environment

Mold illness extends beyond CIRS, encompassing conditions like mold allergy and toxicity, as well as other health impacts ranging from respiratory issues to chronic fatigue. Early recognition of these varied risks and the seeking of professional help can significantly improve indoor environmental safety. If you suspect mold in your home or workplace, early identification and prompt action are crucial. Mold Inspection Sciences offers expanded services under their mold-related illness and CIRS program (MRIC), ensuring you receive the expertise needed to maintain a safe indoor environment.
