Dorms are being deep cleaned at the University of Maryland, as students are growing increasingly concerned that mold problems may be linked to the death of a freshman. According to Fox News reporting, Olivia Paregol, 18, died from the same rare virus that killed 11 children in a New Jersey healthcare facility.
Paregol developed a cough, which later worsened to pneumonia. She died from adenovirus on Nov. 18 at Johns Hopkins Hospital. This is less than three weeks after the school learned she had the illness. The university has since said five more students have illnesses tied to the same rare virus.
Some students said they found mold on their shoes and clothes in their dorm back in August — and believes the fungus caused them to fall ill. After they repeatedly alerted university officials, about 500 students were moved to temporary housing while the school worked to clean the dorms.
Paregol – who suffered from Crohn’s disease and a weakened immune system – lived in Elkton Hall, one of the dorms evacuated for cleaning.
Dr. David McBride, head of the university’s campus health center, said the university has stepped up the cleaning efforts and is on high alert.
Earlier this year these same dorms were involved in a study that looked at how influenza spread in close quarters.
Knowledge about the potential benefits and possible problems of air duct cleaning is limited. Since conditions in every home are different, it is impossible to generalize about whether or not air duct cleaning in your home would be beneficial.
If no one in your household suffers from allergies or unexplained symptoms or illnesses and if, after a visual inspection of the inside of the ducts, you see no indication that your air ducts are contaminated with large deposits of dust or mold (no musty odor or visible mold growth), having your air ducts cleaned is probably unnecessary. It is normal for the return registers to get dusty as dust-laden air is pulled through the grate. This does not indicate that your air ducts are contaminated with heavy deposits of dust or debris; the registers can be easily vacuumed or removed and cleaned.
On the other hand, if family members are experiencing unusual or unexplained symptoms or illnesses that you think might be related to your home environment, you should discuss the situation with your doctor. EPA has published the following publications for guidance on identifying possible indoor air quality problems and ways to prevent or fix them.
You may consider having your air ducts cleaned simply because it seems logical that air ducts will get dirty over time and should occasionally be cleaned. While the debate about the value of periodic duct cleaning continues, no evidence suggests that such cleaning would be detrimental, provided that it is done properly.
On the other hand, if a service provider fails to follow proper duct cleaning procedures, duct cleaning can cause indoor air problems. For example, an inadequate vacuum collection system can release more dust, dirt and other contaminants than if you had left the ducts alone. A careless or inadequately trained service provider can damage your ducts or heating and cooling system, possibly increasing your heating and air conditioning costs or forcing you to undertake difficult and costly repairs or replacements.
You should consider having the air ducts in your home cleaned if:
There is substantial visible mold growth inside hard surface (e.g., sheet metal) ducts or on other components of your heating and cooling system. There are several important points to understand concerning mold detection in heating and cooling systems:
Many sections of your heating and cooling system may not be accessible for a visible inspection, so ask the service provider to show you any mold they say exists.
You should be aware that although a substance may look like mold, a positive determination of whether it is mold or not can be made only by an expert and may require laboratory analysis for final confirmation. For about $50, some microbiology laboratories can tell you whether a sample sent to them on a clear strip of sticky household tape is mold or simply a substance that resembles it.
If you have insulated air ducts and the insulation gets wet or moldy it cannot be effectively cleaned and should be removed and replaced.
If the conditions causing the mold growth in the first place are not corrected, mold growth will recur.
Ducts are infested with vermin, e.g. (rodents or insects)
Ducts are clogged with excessive amounts of dust and debris and/or particles are actually released into the home from your supply registers.

House fires are terrifying because the flames can cause intense bodily harm that results in serious injury and even death. Once the fire is put out, many homeowners are relieved in the sense that the threat to their life or health has ended. However, the flames themselves are not the only potential source of health issues. Many of the byproducts of a fire are toxic. Fires leave behind smoke, soot, corrosive byproducts, and even mold that negatively affects your health. It is important to know the health risks caused by the byproducts of a fire to keep yourself and your family safe in the aftermath.
All fires involve smoke and everyone knows that smoke inhalation is extremely dangerous because of the chemicals it contains. Smoke is the byproduct of incomplete combustion and contains the following toxins:
Carbon Monoxide (CO) and Hydrogen Cyanide (HCN): The potential health effects of carbon monoxide are well known as many homes have carbon monoxide detectors for safety. Less people know about the risks of the other major chemical in smoke, hydrogen cyanide. Hydrogen cyanide is over 30 times more toxic than carbon monoxide and inhaling a combination of both can be deadly. Smoke inhalation is the leading cause of fire related deaths.
Chemicals from Burnt Materials: When materials such as wood, drywall, and flooring are burned in a fire, they release hundreds of chemicals in the smoke that are harmful to your health. Some of the dangerous chemicals released by burning household materials include hydrogen sulfide, hydrogen chloride, carboxylic acids, nitrogen oxides, acid gases, sulfur dioxide, and much more.
After the fire and smoke have cleared, there is still a substance present that can spread throughout the home and cause health issues as well as property damage; soot. Soot is dangerous because it spreads and settles everywhere including the air ducts where it can get redistributed into the air. Most health problems caused by soot result from inhalation but soot can also get absorbed in the skin and eyes. The main health effects from soot include lung irritation and respiratory issues such as bronchitis and asthma as well as more serious issues including heart attack, stroke, and even cancer.
Few people associate mold growth with house fires but if a house fire is extinguished with water, this excess moisture can quickly lead to mold growth. Moisture is the main cause of mold growth and organic materials that are wet from putting out the fire can become contaminated with mold within 48 hours. Mold not only adds to the health risks already present after a fire, but also causes even more property damage that makes the restoration process longer and more expensive.
If a fire breaks out in your home, make sure that everyone evacuates safely and do not return to your home until it has been restored and deemed safe. The byproducts of a fire are just as dangerous as the fire itself and can cause serious health effects long after the fire has been put out. It is of extreme importance to begin the fire damage restoration as soon as possible by hiring professionals that can safely remove dangerous byproducts from soot and smoke. These professionals have effective cleaning products and personal protective equipment to keep themselves safe during the restoration process

Did you know that, according to the U.S. Centers for Disease Control and Prevention, more than 25 million Americans, including roughly seven million children, have asthma? It’s true, and those numbers have steadily risen in recent years.
Asthma is more than occasional wheezing or feeling out of breath during physical activity. Asthma is chronic and can lead to coughing, wheezing, shortness of breath, fast breathing, and chest tightness, states the Asthma and Allergy Foundation of America. In the 21st century, people spend significant time indoors at home, school or work, and indoor air environments could be triggers for asthma. Improving indoor air quality can help people breathe clearly. The AAFA notes that the following agents can adversely affect indoor air quality, potentially triggering asthma attacks.
Allergens such as mold, dust mites, pet dander and fur, and waste from insects or rodents thrive in many homes. Ensuring indoor air quality is high can cut back on the amount of allergens in the air. People with asthma can invest in an air purifier and vacuum regularly, being sure to use a HEPA-equipped appliance. Routinely replacing HVAC system filters can help prevent allergens from blowing around the house. Also, frequent maintenance of HVAC systems will ensure they are operating safely and not contributing to poor indoor air quality.
Mold can be mitigated by reducing moisture in a home. Moist environments in the kitchen and bathroom may promote mold growth. Ventilation is key to keep mold at bay.
Thirdhand smoke, or THS, may be unfamiliar to many people. A 2011 report published in Environmental Health Perspectives says THS is an invisible combination of gases and particles that can cling to clothing, cushions, carpeting, and other materials long after secondhand smoke has cleared from a room. Studies have indicated that residual nicotine levels can be found in house dust where people smoke or once smoked. Studies have indicated that smoke compounds can adsorb onto surfaces and then desorb back into air over time.
Keeping tobacco smoke out of a home can improve indoor air quality and personal health.
Volatile organic compounds, or VOCs, are gases released from commonly used products. These can include paints and varnishes, cleaning supplies, air fresheners, new furniture, and new carpet. People with asthma may find that VOCs can trigger attacks. Airing out items, reducing usage of products that are heavily scented and choosing low- or no-VOC products can help. Making cleaning products from baking soda, vinegar and liquid oil soap also can keep indoor air quality high.
Homeowners who plan to renovate their homes can consider using the appropriate specifications for HVAC systems to promote good indoor air, as well as address any other potential problems that may be compromising indoor air quality.
Mold is a common household nuisance and is found both inside and outside in varying amounts. For some people, mold and its spores cause very few problems, while for others it can be devastating—even life threatening. In the U.S., there are over two million children with chronic and other serious conditions that are at higher risk for the dangers that mold in their homes and schools can cause. This is due to their weakened immune systems that leave them more susceptible to infection and allow mold to have a more harmful impact. As many as one-third of the children in the U.S., including those who are considered to be “healthy,” are at risk for allergic reactions to mold. Babies that have been exposed to mold, even without incident, may be at a higher risk for developing allergies and even asthma as they get older, which is why mold exposure can be damaging even if no negative symptoms are immediately detected.
Symptoms of mold allergies are typically similar to those of other allergies, which can make it harder to determine the cause. These include sneezing, runny nose, itchy eyes, wheezing, and coughing. However, symptoms can escalate to more serious problems such as respiratory and circulatory issues. Mold flourishes in warm, damp environments, which is why warm summer temperatures frequently stir up mold allergies. Make sure to stock the medicine cabinet with the appropriate tools and treatments for babies and small children in order to be prepared to treat any symptoms.
t is important for local health departments to take steps to educate families in their area on this issue to prevent easily avoidable dangers. The remainder of this blog include valuable tips and resources on mitigating health risks related to mold exposure.
Stopping Mold Before It Grows
Prevention is always easier than treatment, especially with mold. Once it gets started, some molds are more difficult to control and may require additional treatments and work. Local health departments should educate their community members on taking the following preventative measures to reduce health risks associated with mold exposure.
Reduce humidity in the home:
Because mold thrives in warm and wet conditions, try to keep dampness to a minimum. Install a dehumidifier if necessary. Open windows for ventilation, but close them when there are reports of higher humidity levels.
Keep houseplants to a minimum in rooms that may be at higher risk of mold growth, such as rooms with high moisture levels and low ventilation.
This is especially important in rooms that do not get visited often, such as the basement, where signs of mold growth can go undetected for longer periods of time.
Do not use carpeting in the bathroom, especially with children. Use washable mats or a towel on the floor instead. Dry the floor as soon as possible.
Bathrooms are particularly vulnerable to mold growth, because they often do not have windows, which makes ventilating the damp area more difficult. If there is a window, open it often to dry out the bathroom.
If there is an exhaust fan in the bathroom, turn it on as soon as the bath is done so that the room gets dried up quickly.
Other common areas for mold growth include the shower curtain and around the bathtub and the sinks.
Any appliances that require water are common places for leaks and mold growth. Be sure to inspect under refrigerators, icemakers, dishwashers, coffee makers, etc.
Repair any leaking pipes. Clean up any water immediately and use a fan to make sure that any moisture is dried.
Increase the drainage away from the house to protect against leaks.
Summer Toys: The Perfect Hiding Spot for Mold
Pool, bath, and teething toys are breeding grounds for mold, because they can hold a lot of moisture and harbor mold growth undetected for long periods of time. Local health departments should provide the following prevention and treatment tips to limit mold exposure for children engaging in summertime activities and during bath time.
During summer months, kids are playing with many moisture-laden toys to keep cool such as pool noodles, water guns, absorbent animals and balls, and all sorts of inflatable pool toys. Make sure these and other water-friendly toys are squeezed out and left out to dry before storing them after use.
Eliminate the risk by using alternative toys such as measuring cups, stacking blocks, and other items without places for water to hide. The advantage of these toys is the ability to toss them directly in the dishwasher after swimming or a bath.
Swimsuits and towels are also used and re-used frequently in the summertime. Do not leave either of these sitting in a ball somewhere. It is important to pick them up and spread them out in a ventilated or breeze spot so they can completely dry out before use.
Be sure to regularly wash suits, towels, and any other damp clothing.
For regular bath toys, one option is to plug the small holes with water-resistant glue. This keeps them from squeaking and/or shooting water but keeps them mold free.
Boil bath toys about once a week, and allow them to air dry completely.
Soak toys in white vinegar overnight to clean them. The vinegar odor will dissipate as it dries.
Teething toys can also harbor moisture for mold to grow. Squeeze all of the water or drool out of rubber or mesh teething toys and clean them using a damp cloth.
Teething and bath toys can be run through the sanitize cycle on the dishwasher and then allowed to air dry.
A Surprising Source of Mold
One of the most surprising sources of mold problems can be found in children’s sippy cups/water bottles, used increasingly often during summer months as a source of hydration. Many people do not completely disassemble sippy cups when they are cleaning them, greatly increasing the potential for mold growth. Local health departments should provide the following cleaning steps for sippy cups/ water bottles to minimize and eliminate mold growth:
If there is a rubber or plastic ring on the lid of the sippy cup, make sure to pull it out and rinse under it carefully.
Look for sippy cups with solid, one-piece lids, but make sure to clean the spout or drinking straw as well.
All of the cups and parts can be washed in the dishwasher. Make sure that everything is completely dry before reassembling them.
Disposable water bottles should not be reused, not only because of the risk of mold but because the plastic can leach into the water and can be harmful to a child’s health.
Metal water bottles are good because they keep drinks cooler and are easy to sanitize in the dishwasher.
Whenever in doubt over whether mold was completely cleaned from a toy, it is best to be safe and throw it out.
The Critical Role of Local Health Departments
Families with young children should be able to enjoy cooling off in the summer heat risk-free. Unfortunately, many parents and guardians are unaware of the hidden dangers that lurk in the nooks and crannies of their child’s toys. As a result, it is vital that local health departments provide ongoing and visible guidance to highlight the various health risks associated with mold and how to protect their child from exposure. For example, local health officials can disseminate the facts and tips included in this blog via their websites and social media pages, or by engaging in traditional community outreach (e.g., distributing pamphlets, one-pagers).
