In Australia, we're currently suffering from torrential rain all along the east coast, affecting Queensland and New South Wales and potentially moving towards Victoria. Regardless of where you're living, unexpected water damage and mould may be a new problem for you to begin dealing with. This live stream and podcast will focus on how to deal with mould and water damage affecting paper documents. We can all imagine sodden books and libraries underwater, but I'll leave that problem for the archivists. This show segment will focus exclusively on how you can deal with mould contamination of paper documents.  To do this, I’ll review a recent paper that came out that looked at how to sterilize paper during a crisis. The authors compared two types of sterilization methods called (1) gamma sterilization which uses radiation to perform cold sterilization and (2) dry heat sterilization. Why this paper is interesting is that all of us have access to dry heat using a convection drying oven.  The scientists performed several types of tests looking at the efficiency of gamma radiation versus dry heat. They discovered that gamma radiation inactivated 100% of the test organisms, including fungi and gram-positive and gram-negative bacteria but what about the efficacy of dry heat? The scientists looked at three temperatures: 100, 150, and 200 degrees Celsius for 15, 30 or 60 minutes. They also looked at the impact of two different sterilization techniques on the structural integrity of the paper using scanning electron microscopy. When we focus only on fungi, (because bacteria are easier to kill)  it was shown that a conservative temperature of 100 degrees Celsius for 15 minutes achieved a 97.1% inactivation. This also had the lowest comparative impact on the paper structure.  Obviously, other methods of water damage restoration indoors such as increasing ventilation to provide additional air circulation or the use of a dehumidifier are also valuable methods of dealing with water damage.  The take-home message from this paper is that a convection oven can effectively disinfect and nearly sterilize water-damaged papers using a conservative time and temperature of 100 degrees Celcius for 15minutes.  I hope this information helps any persons dealing with mould contamination of paper documents. REFERENCES: Alshammari, F.H., Hussein, HA.A.

Many people ask me the question: can you really get sick from spending time inside a water-damaged property? Or another related question: Does mould really make people sick? Sometimes I even get questions along the lines of: I can understand why people might not like the smell of mould or even its visual presence, but surely, a little bit of mould can't hurt you? If you've ever been part of these conversations, and want definitive proof that mould can in fact, cause serious problems for occupants then this live stream and podcast is for you. A paper came out at the end of 2021 in the Journal of Hygiene and Infection Control, discussing the situation for a family of five, who developed severe health problems after spending six years inside a water damaged home.  Your first reaction might be: why did they stay six years? For many people, this is unavoidable and for this family, it was because it was a new home construction.  They battled on trying the get the builder to fix the problems. This case study deep dives into something called building-related illness and explores its relationship with sick building syndrome. The paper is important because it includes an evaluation of the home from an Occupational Hygiene viewpoint as well as the Environmental Medicine perspective. This case study highlights many of the building-specific factors that contributed to water damage and mould as well as the complaint pattern and medical symptoms that were experienced by the children, the mother and the father.  The outcome of this case study revealed that until the family changed their place of residence unwanted health complaints persisted. But once they left the father's health symptoms improved after two weeks. The three children took six months to recover and the mother's symptoms went away after 18 months. This paper highlights that long term exposure to mould was the cause of building-related illness. Use this paper to support your position especially if you're ever needing to prove the health hazards from mould inside buildingsREFERENCE: Kramer A, Wichelhaus TA, Kempf V, Hogardt M, Zacharowski K.

I'm often asked whether mould affects children's health? I thought this would be an appropriate topic to kick off the new year for The Mould Show in 2022. In approaching this topic, I'm going to review some of the key symptoms associated with exposure to mould and then provide you with an easy visual guide that you can use to not only remember the typical mould symptoms but the causes and effects but that may be helpful when describing indoor air quality issues in your home or workplace.We all know that unexpected weather increasingly contributes to mould problems indoors in addition to water leaks and home dilapidation problems. In turn, most of us understand that moulds grow on wet surfaces and release their spores into the air.  It’s important to remember that mycotoxin levels inside water-damaged buildings are sometimes 1000-fold higher than the mould count. It's also known that 50% of fungal growth can be hidden and is missed by mould testing according to the EPA.  Find out what the key research papers say about mould and your child's health?REFERENCES:Campbell AW, Watson P.

When you think about the over 5M fungal species that exist on the planet and juxtapose this against the approximate 2000 mushrooms species we might eat as food - there really are a lot of chance and probable possibilities for us to come into contact with these microorganisms in our everyday lives. This new paper that came out from the Lawrence Berkeley National Laboratory is quite an eye-opener because it looked at how fungal communities inside 1135 homes in the United States is connected with something called the Infection Fatality Ratio (IFR) which describes the number of deaths caused by COVID-19 per 1000 coronavirus infections. Their research showed that an increased fungal diversity especially for specific Species of indoor fungi versus outdoor fungi (Beta diversity) was associated with a reduced infection fatality ratio.  In their paper, they looked at whether there was a correlation between certain Species of fungi and adverse outcomes from COVID? And amazingly they found that “yes” there is! They found that something called the beta diversity assessed from a comparison between fungal spore types collected outdoors and then inside the home living environment was of fundamental importance. The key result is that: high diversity of outdoor fungi when also present indoors is associated with a suppression effect for COVID-19 mortality.This means that collecting spore trap measurements from the outdoors and indoors is very important for predicting adverse events like mortality from COVID-19 and emphasizes the importance of the environment on human illness.  Now it’s not just the raw numbers of fungi, but the overlap of which types are present outdoors and also found indoors which defines different aspects of Species richness and diversity. The research showed that at least four of the following seven fungal genera have a key role in suppressing coronavirus infections. These were: Alternaria, Aspergillus, Epicoccum, Eurotium, Toxicocladosporium and Wallemia as well as a novel Mycosphaerellaceae fungus.  You could argue that simply airing out your property will naturally bring fresh outdoor air containing mould spores indoors. So, wouldn’t that automatically select for the correct beta diversity ratio that’s better for your health?  On the surface, you'd be right to conclude this. However, I've personally done 1000s of indoor air quality inspections over the years and many homes have hidden mould problems that contribute to poor indoor air quality.  This is often caused by water damage and dampness and in most of these cases, there is a skewed distribution of fungi indoors that’s very different to the outdoors.  This publication is extremely important because it shows a correlation effect between bioaerosol counts especially mould spores and respiratory disease outcomes. The key takeaway here is that COVID-19 mortality is suppressed inside homes where the outdoor fungi occur indoors at very similar levels. When the skewness or difference between the outdoor: indoor diversity changes, or when the indoor fungi are significantly different to the outdoors, then COVID-19 mortality increases. These researchers found that fungal beta diversity was a much stronger correlate for adverse COVID-19 outcome as age.  For example, older persons have worse COVID-19 outcomes, and this paper says that fungal beta diversity in the wrong direction is also bad for your health.   The authors stress the method is unlikely to be restricted only to coronavirus but could extend to surveillance of other allergic and viral diseases. This research, therefore, underscores the importance of fungal biosurveillance in the built environment to improve public health outcomes.  REFERENCE:doi:
This week on The Mould Show, I'm going to be talking about censorship of mould illness. And to do this, we’ll be reviewing a paper that came out earlier this year that focused on the situation in Finland. Essentially, this is a battle between free democracy and socialism and the impact that politics has on contemporary scientific thinking and the dissemination of applied science into the wider community. So, what's this all about? Well, most of us understand the connection between bad indoor air quality and water damage and how this can impact our health. However, I'm always amazed when people try to negate this connection between environmental exposure and illness or outright deny the scientific facts. This is very perplexing because on the one hand, when the mainstream media is considering carbon credits, or net-zero, they seem to have no trouble linking the slightest change in the environment with some type of consequence to someone somewhere. In certain socialist, corporatist European countries like Finland, mould related illness has become highly politicized. And today we're going to be reviewing a paper put out by Professor Tamara Tuuminen in May/June 2021.  She is a very courageous scientist and doctor who discusses the fact that even though the epidemiological literature shows an overwhelming consensus that mould induces a multi-organ symptomology way beyond just the sniffles - that many government and corporate institutions in her country of Finland deny this link. She discusses the Government Department of Health and Welfare as well as the Finnish Institute of Occupational Health as two of the key institutions that aim to deny mould as a real environmental illness. Her paper discusses how this is achieved using corporatist special interest groups and educational bodies who often position themselves as independent opinion leaders. In many cases, they are far from unbiased and can demonstrate corruption by not disclosing hidden conflicts of interest or selectively quoting only those academic works of literature that support the government or corporate agenda. In the Livestream, I'm going to present evidence as far back as 1964 showing that this approach is patently false, and any non-brainwashed person can easily verify these facts for themselves.  DYOR and it quite easy then to connect environmental illnesses connected with mould and the many very real physiological problems that can ensue.   I'll also discuss how the Finnish attempt to use mindfulness exercises and referrals to psychologists or psychiatrists, instead of addressing the fundamental problem of indoor air quality and building damage.  Contemporary, mainstream narrative protocols instead blame the person for the sickness and from a clinical perspective, attempt to retrain the patient’s brain to remove the stressful situation. I hope you'll join with me and watch the live stream or download the podcast which touches on multiple areas of contemporary #FollowTheScience and #Censorship of science and how this has become politicized.  I’ll conclude with some recommendations that you can follow to minimize this bias to get at the ground truth and let the science help rather than hurt you.REFERENCES:Tuuminen T. Dampness and Mold Hypersensitivity Syndrome, or Mold-related Illness, Has Become Highly Politicized and Downplayed in Finland. Altern Ther Health Med. 2021 May;27(3):59-64. PMID: 33882029.
In this presentation, I want to review something called salt therapy, which is considered a complementary method for the treatment of respiratory tract illnesses. This will have a special focus on mould related disease.  Clinical practice referrals my Company receives revolve around exposure to indoor air dampness and mould, usually in the home. When this is prolonged, it can cause problems including: vocal cords irritation, rhinitis, cough, wheezing and recurrent infections of the upper and lower respiratory tract. Breathing in bioaerosols might also make existing asthma worse or bring on new asthma in children or adults. Many of the client and patient referrals we receive complain that their doctor does not truly understand their symptoms or may even consider some of these to be psychosomatic. Apart from focussing on fixing the building, what can you do to ‘get well’ if you’re mould affected?  To this end, an important paper recently came out in the Journal: Alternative Therapies in June 2021.  Salt therapy is put forward as a treatment for mould related illness. But what is it and why does it work?Salt therapy has developed into a holistic complementary therapy available in day spa-like environments based on observations made by a 19th century Polish doctor, Feliks Boczkowski.  He noticed that salt mine workers had far fewer skin and respiratory health symptoms compared with other mine workers. Later during World War II in Germany, people who sheltered during bombing in salt caves were observed to experience relief from respiratory problems. Salt therapy exploits or mimics the microclimate of natural salt caves. People who spend time in these caves are take advantage of what is called Spleotherapy in the literature. This involves inhaling pure sodium chloride, NaCl along with other aerosolized elements including magnesium and calcium. A different version termed Halotherapy allows people to experience the benefits of salt therapy by spending time in a room that has salt coated walls and floor. Halotherapy may also use a generator (termed a halogenerator) to produce fine sodium chloride aerosols (1-5-micron diameter) which are aerosolized in the ‘salt room’.  The salt easily penetrates into all parts of the respiratory tract and has antibacterial and anti-inflammatory properties. Salt particles also promote ciliary transport in the lung, allowing mucus plugs to be coughed up and it also reduces IgE inflammatory levels. Doctors have used salt therapy in the treatment of allergic rhinitis, asthma, COPD, bronchitis for cystic fibrosis and for viral bronchiolitis. There is even research support linking the use of salting of face masks to neutralize the SARS-CoV-2 virus in an effort to combat COVID-19.  Salt therapy is known to be 100% natural and it's generally safe because it improves the clearance of particulates from the lung, often provides relief from coughing and reduces bronchial inflammation.  It’s easily experienced by spending time in a salt room (30-60 min. sessions) repeated 10 to 20 times.  If your home might be mouldy, then consider salt your new ally for health promotion.REFERENCES: Wasik AA, Tuuminen T.

Black fungus disease can have a devastating impact for people who contract COVID 19 and even for those who are recovering from COVID-19 and who are more properly classed as COVID long haulers.  My purpose in presenting this live stream is really to bring about awareness to every person about the potential impact of black fungus and explore some of the reasons why everyone should be aware of post-COVID infection co-infection with black fungi. It is my hope that this live stream prevents unnecessary illness, infection and even death.  So, what are the common types of black fungus and why is this connected with COVID? To answer this question, I need to focus on two of the most common fungi that are implicated in mucormycosis and they are from the Genus that includes Rhizopus sp. and Mucor sp. These are typically fast-growing fungi that produce copious spores. The problem is that these black coloured fungi in the immunocompromised hosts such as those recovering from COVID can utilize the iron in blood as a food source. It must be remembered that the pre-COVID infectious period includes the one to two weeks prior to symptoms. The next month is the acute phase of COVID infection. And after five weeks, this is the post-COVID-19 period.  Those admitted to hospital are commonly offered steroid medications. These steroids like dexamethasone work by dampening down the body's immune system, but at the same time they also increase the levels of iron in the blood, which the black fungi use as a food source. Although dexamethasone does work and is a relatively inexpensive medication, it is a problem for treatment, especially when this has become widespread due to the fact that although it produces an anti-inflammatory effect, this property is at the same time, immunosuppressive in action. These mean this steroid has two contrasting properties as a treatment.  There are many ways in which black fungus can enter the body. Depending on where it enters, this determines the impact of the severity of the fungal infection.  So, what is the takeaway from this particular livestream? Number one, it's very important that you know whether or not you are at risk. Just because you've recovered from COVID 19 does not mean that your body is capable of neutralizing invading pathogens like the black fungi. Everyone should be mindful of the fact the indoor living environment has an effect on your overall health and predisposition to infection. Therefore, inadequate hygiene, high humidity, and water damaged materials can cause an already compromised immune system to become susceptible to various diseases.  REFERENCES: Pushparaj K, Kuchi Bhotla H, Arumugam VA, Pappusamy M, Easwaran M, Liu WC, Issara U, Rengasamy KRR, Meyyazhagan A, Balasubramanian B.

Studies have shown that people are healthier, more comfortable and more productive in structures with good indoor air quality (IAQ). Be that as it may, I've had a first-hand experience as an indoor air quality and mould inspection expert not only about the huge impact of moulds and water damage on people’s property but also the emotional distress these things can cause them. According to studies, there exists a huge relationship between emotional wellbeing and particulate matter pollution, and a very strong numerical relationship between mould spore counts, the presence of water damage, including hidden mould, and measures of particulate matter in the PM 2.5 and PM 10 size range. And as the concentration of PM 2.5 particles in the air increases, levels of happiness decrease. As the concentration of PM 2.5 pollutants increases, levels of tiredness, stress and sadness all increase. Read the blog here: RM, Das K, Fan Y, Barkjohn KK, Botchwey N, Ramaswami A, Russell AG.

Hot water or cold water, detergent or the latest green-cleaning additive.  What does the literature say?  If you want to reduce germs, how best to wash?  That's the 3-minute topic today!
Prevention, they say, is better than cure. And that forms the basis of preventive medicine, a proactive approach aimed at getting ahead of the potential causes of diseases by promoting healthy behaviours and screening for diseases with the aim to keep people from becoming sick in the first place rather than treating diseases when they eventually occur. In this week on The Mould Show, I dive into the emerging social media, audio-only platform called Clubhouse.  Here you'll find a large range of healthcare, wellness, and medicine focussed groups (as well as many others) that are relevant to biotoxin illness. After listening in, making some rooms, creating a club or two, and talking into these rooms, I'm reviewing some of the key takeaways around the future of healthcare.   Synopsis: Disease and disability are affected by environmental factors, genetic predisposition, disease agents, and lifestyle choices and are dynamic processes which begin before individuals realize they are affected.Read more on the blog here:
Do you know that the most humid parts of the world are Kuala Lumpur in Malaysia; Jakarta, Indonesia; and Singapore, all in South and Southeast Asia as well as Darwin in Australia? This underscores the need to maintain an indoor living environment that is free of mould because of the huge challenges of living in a humid climate. Although mould poses a great risk, especially to those living in humid climates, there are still some practical control measures that can be adopted to stop the growth of mould or reduce its impact. They include the control of moisture, nutrients and temperature. Find out more on the blog:
Mast Cell Activation Syndrome (MCAS) is a very serious, often overlooked condition. About one in four people with the disease cannot work or participate in normal day-to-day activities. It is a disease that affects people of all ages or gender, but one funny thing about it is that it is often unrecognized and possibly remains undiagnosed in many cases.MCAS is a group of diseases involving the immune system. When the triggers occur, antigens are raised inside the body, which might result in itchiness, for example. But this also leads to a histamine cascade, which causes contraction of the respiratory vessels. Then blood vessels dilate and result in gastric acid secretion. Many people with MCAS can have very serious life-threatening reactions such as anaphylaxis. Typical symptoms include itching, headaches, brain fog, fatigue, heart palpitations, hives, shortness of breath, gastrointestinal problems, wheezing, low blood pressure, anxiety and, very typically, a flushing or a swelling, which appears on the face or body.  According to the American Academy of Allergy Asthma & Immunology, Mast Cell Activation Syndrome is a condition in which the patient experiences repeated episodes of the symptoms of anaphylaxis – allergic symptoms such as hives, swelling, low blood pressure, difficulty breathing and severe diarrhea. High levels of mast cell mediators are released during those episodes. For these reasons, it is therefore important that you are very much aware of the top seven underlying factors that can contribute to Mast Cell Activation Syndrome and avoid them completely so you can live a healthier, happier life. REFERENCES:Kritas SK, Gallenga CE, D Ovidio C, Ronconi G, Caraffa Al, Toniato E, Lauritano D, Conti P.

According to statistics, about 90 percent of our time is spent indoors. The number could be much higher in recent times due to COVID-19 which has caused many governments around the world to impose lockdowns and forced people, including children, to stay home in order to avoid contracting the virus and halt its spread.But more worrisome is the fact that these kids are also exposed to other dangers – like the threat from airborne allergen exposure in their early lives.The American Academy of Allergy, Asthma & Immunology defines an allergen as a usually harmless substance capable of triggering a response that starts in the immune system and results in an allergic reaction, like sneezing or itching. For instance, if you have an allergy to pollen, your immune system identifies pollen as an invader or allergen.  But the reaction event can turn serious and also be overlooked. How then does the indoor living environment affect children? A recent study in environmental medicine from the University of California's Institute of Integrative Immunology looked at early life exposure, including prenatal exposure and how this can be linked to behavioural changes, growth delay and neuroimmune complications; and made some startling revelations. The researchers found that children exposed to allergens, including water damage, and mould in the womb for up to two years may display growth delay, allergic rhinitis, asthma, allergic dermatitis, motor problems and speech delay whereas when older children – that is those between the ages of two and five – are exposed to mould and water-damaged environments, they display symptoms, including allergic rhinitis, motor problems, behavioural problems and speech delay. Did you see the elephant in the room?  All the children were experiencing seizures!  This symptom is a lot worse than just a runny nose isn’t it? The doctors presented three case studies and the children involved all showed positive allergy tests to the following four fungi: Alternaria, Penicillium, Aspergillus fumigatus, and Rhizopus. They, therefore, concluded the following. That:The developing immune system can show an aggressive response to environmental danger signals. As a result of prolonged cytokine release caused by an allergic response, seizures and behavioural instability can occur.Indoor environmental triggers like mould, mycotoxins, dust mites and other particulates can lead to a skewed neuroimmune response. The solution by the doctors, especially to reduce immune activation and control the appearance of seizures, was in all cases to, firstly, identify if children were living in unhealthy households during the mother's pregnancy and during early life, and then determine if they were sensitized to mould. If the home inspection or assessment revealed allergen conditions like mould or water damage, then the doctor could recommend relocation to a mould-free home, an action known as mould avoidance.So, the main point here, even as scary as it is, is that epileptic seizures and other abnormal behavioural problems were simply the result of mould exposure. When in doubt, get it tested.You should also now know that indoor air quality is not restricted to allergy and asthma problems alone. It could have more far-reaching consequences. It then behoves you as parents with young children, pregnant mothers and their partners, grandparents, childcare workers, property managers and landlords as well as integrative medical doctors and allied healthcare practitioners to take more drastic measures aimed at protecting these children from allergen exposure at their very early age, even in the midst of the pandemic.REFERENCES:
I received an email the other day from a client with bad news informing me that his wife has breast cancer.  He told me that she had suffered from depression ever since reluctantly moving into a property that had a severe water damage problem and that had been concealed by the real estate agent.  This got me thinking about all the research talking about mould exposure and mood disorders like anxiety and depression and even IQ.In this week’s Livestream, I’m going to review 6 key areas where mental health problems can occur due to mould and water damage:1.

Common health concerns from mould include: asthma, allergic rhinitis, wheeze, cough, shortness of breath, or hypersensitivity pneumonitis, headache, eye and skin problems and other health issues.  It is reasonably well known, at least by the integrative health community, that exposure to moulds and other fungi is correlated with a range of allergic and pulmonary diseases in susceptible individuals. Allergy is often tested using antigen extracts. The paper we're discussing today shows that the available antigen extracts are not well matched to the types of fungi that are commonly found indoors. Allergic sensitization is measured in vivo by something called the skin prick or intradermal testing method or by serological testing against a panel. Fungal antigens are therefore used to determine reaction and it is an important clinical diagnostic that supports environmental inspections. It is also known that environmental remediation is correlated with improved outcomes of hypersensitivity pneumonitis and asthma. But linking these conditions with buildings relies on either the environmental inspection or the clinician being able to prove the allergy using fungal antigens. This important paper shows that the actual spore counts in the air reveal exactly which fungi are most likely to induce allergy. The research reviewed nearly 25,000 indoor air samples from over 7,500 mould affected or complaint homes and compared them against nearly 30,000 outdoor air samples. It was found that the Penicillium fungus was the dominant Genus in water damaged homes and was more common than Aspergillus. Overall five important Penicillium Genus fungi and three Aspergillus Genus species were identified as the predominant indoor water damage related fungi. Notably, none of the Penicillium species and only one of the Aspergillus species have a clinical antigen extract available for skin testing or serum testing. The conclusions show variously that commercial production of additional antigen extracts are required and that air spore count measures are fundamentally important to determine risk level of the indoor air versus the outdoor air. So, what is healthy air versus unhealthy air? The researchers review the recommendations put forward by the American Industrial Hygiene Association (AIHA) who state that higher indoor versus outdoor mould levels, determined using either viable Petri plate culture or spore trap air sampling should be considered as unhealthy. This new research also introduces a new quantitative minimum threshold risk level: Where the combined concentration level of Penicillium/Aspergillus fungi in the indoor air is greater than 200 colony forming units per cubic meter of air (CFU/m3) higher than in the outdoor air. This may be an appropriate evidence-based benchmark.This research concludes by stating that the accuracy of clinical detection of mould sensitivity can be significantly improved by (1) adding new antigen extracts for the predominant species of Penicillium and Aspergillus commonly identified in damp and mould affected homes and that (2) this will lead to improved outcomes for individuals who suffer from mould related conditions so that (3) timely environmental interventions such as (4) patient relocation and or (5) mould remediation when required can be implemented as a (5) critical component of disease management to improve the outcomes of asthma and hypersensitivity pneumonitis in the built environment.REFERENCE:Misalignment between Clinical Mold Antigen Extracts and Airborne Molds Found in Water-Damaged Homes.

Summer is approaching, at least for us here in Australia and for some of us, looking down at our toes might bring on a "yuck" reaction. Why are those nails cracked, fragile or showing discoloration? Are you embarrassed by this? What's causing it? How do I stop it?  Is this a sign of something worse?That's the topic of this week's show. And importantly, we're going to be talking about how the health of your toenails and even the health of the nails on your fingers can be used as an indicator of overall health. To do this, we're going to go through some of the most common questions around nail fungus including symptoms and which groups of people are most likely to get fungal nail infections? What are the terms about this microbial infection and what are the typical fungi that cause this? We'll also talk about some of the environmental hazards for foot fungus as well as how it's diagnosed at the lab and then move on to how you can prevent fungal nail infections and discuss some of the treatments from the research literature. With this foundation we'll then move on to the central topic of today's presentation, which is looking at the association between foot and nail fungus and COVID 19 clinical outcomes and we'll be discussing what the scientists discovered and why it's very important to deal with fungal nail infections because they do have an impact on the clinical outcomes of respiratory illnesses like COVID-19. REFERENCES:Rakita U, Kaundinya T, Guraya A, Nelson K, Maner B, Manjunath J, Schwartzman G, Lane B, Silverberg JI.

Have you ever wondered whether there's a connection between the seasons and flu like epidemics? Well, this week on The Mould Show, we're going to be looking at two recent pieces of evidence, which focus on the fact that current models for flu-like epidemics are not sufficiently explained by the seasonality effect. Now, most of us would think to ourselves that colds and flus are often more frequent in the cooler winter months, and that gives rise to the seasonality effect. However, two papers have recently provided some stunning evidence suggesting that there is a strong statistical association between exposure to pollen and mould and the infection potential of flu-like illnesses.  We know that pollen is allergenic and that it's linked to immune-activation and defence against a range of different respiratory viruses. But, interestingly, it seems to create a bioaerosol that when inhaled, seems to lower the reproduction number of flu-like viruses. These results for pollen were quickly followed up on by another research group that decided to look at whether or not there was a correlation with mould spore exposure. And that's the main focus of this live stream. The follow-on paper and results show again, a statistically strong correlation between the total bioaerosol count, the total pollen count, and the total mould spore count and presentations to hospital emergency departments for influenza-like illnesses. The final part of the presentation will review how the authors have used mould spore counts and pollen counts to show that COVID-19 presentations and hospitalizations are correlated with the airborne mould spores and pollen counts. This data has significant implications for how we understand disease transmission of flu-like illnesses and chosen interventions against. I look forward to you joining me for this exciting episode.References:Confirmation of an Inverse Relationship between Bioaerosol Count and Influenza-like Illnesses, Including COVID-19.

If you've ever found yourself having trouble explaining to someone why you just don't feel right inside that room or building, then you'll want to watch this.  Ok, you might just sneeze a little over springtime when exposed to pollen...but what if those types of symptoms happened to you every time you clocked in at work?  How do you make sense of this?  Sick building syndrome is a catch-all term that is often used to describe the constellation of symptoms that may occur if you react to this "something" indoors.  There's also the problem of long-term exposure.  If you're constantly exposed to a challenging environment, your symptoms may get worse.  That's the topic of the show today and will focus attention on what clinicians know lies beyond sick building syndrome.  I'll go over what they know about multiple chemical sensitivity, hypersensitivity and chronic fatigue.  The research shows that the duration of exposure along with other co-morbidities leads to a worsening of symptoms and an expansion on the clinical definitions of illness. I conclude with commentary on the important role of site testing and the need for microbiology data.  There's a self-serving reason why your insurance-led occupational hygienist or landlord or rogue builder might want to dismiss your claims about health and water damage and mould exposure.  There's also a simple argument against such self-serving claims.  That's called "Lege artis:" and is Latin for the need to sample the environmental microbiology and toxicology in the same way any other diagnostic specimen is taken.  Don't allow any authority to rely on a visual inspection or say that no visible mould was seen and hence there is no problem.  Use and be aware of the "Lege artis" and the fact there are multiple Standards and Guidelines for indoor air quality and water damage and microbial assessment.  Don't led no data or poor data compromise your health or the lie that mould isn’t a problem as long as we dry out your building.  Remember there’s an industry who want your money for works that are all too often poorly implemented or unverified for source removal.  If you’ve ever been sold the snake oil that “we’ll just fog to treat the mould” recognize that that’s not removing the microbial risks and dead mould can still cause a serious immune challenge.  This Livestream is for all those that need that one publication to help explain and support how they feel and where the science is at around this topic of risk and exposure to water damage and mould.  Reference:Tuuminen T.

Asthma is a common respiratory condition causing an attack or spasm of the bronchioles or airways that carry air to the lungs. Asthma makes it difficult to breathe and in Australia affects one in nine people equivalent to 2.7 million Australians. In the period between 2017-2018 nearly 40,000 hospitalisations occurred. It's known that 80% of asthma hospitalisations are preventable. Now it's not just the hospital costs - asthma affects quality of life. Asthma sufferers self report their wellbeing as "fair" or "poor" compared with other people without asthma. Some interesting research was recently published in the journal, Indoor Air in September 2021.  It looked at what household features contribute to biocontamination and that are linked with asthma. What are some of the typical biocontaminants that might cause asthma-type health effects? Most of us can recall images of pollution haze and coughing, but different types of microorganisms, dusts and pollens and household behaviours are also likely suspects. The paper I'm highlighting is from Canada and the scientists collected dust from people's homes to determine the concentrations of: house dust mite allergens, cat allergens, cockroach allergen, beta-(1,3)-D-glucan and endotoxin levels. They also used a questionnaire as part of home inspections to ask about features and behaviours in the home. What did they find?They discovered that the age of the home and whether or not carpets were present along with the history of water damage and mould odour were positively associated with the presence of multiple indoor contaminants linked to asthma. They also found that high floor cleaning frequency and the use of dehumidifiers were negatively associated with the presence of multiple indoor contaminants. This live stream will review this data and list the Top 8 asthma and allergy triggers. I've also created a free survey so you can measure your own home for risk factors linked to asthma and allergic disease.  You can find the survey here: L, Miller JD, Van Ryswyk K, et al.

On the 22nd October 2021, Victoria, Australia begins our own Freedom Day.  But is this really freedom? State-wide vaccine mandates are in force and there's a need for vaccine passports to enter retail.  For many, significant restrictions remain. The State is still under a form of medical apartheid.  Strict coercion around freedom of choice has forced many to choose vaccination just to re-enter society or keep their job.  The censorship around therapeutic options and facts and figures and open debate have largely been silenced across the mainstream media. This short Livestream discusses a very recent publication that came out (20th October 2021) on the preprint server, medRxiv. This paper serves as a warning around the very real risks of transmission among the vaccinated. Please read it for yourself and consider the results and conclusions. REFERENCE:Evidence of transmission from fully vaccinated individuals in a large outbreak of the SARS-CoV-2 Delta variant in Provincetown, Massachusetts
