Global Coronavirus Outbreak 2020

The outbreak and rapid spread of a new coronavirus from China has caused great concern worldwide as the virus is highly contagious and spread in air, from contaminated surfaces and via personal contact.

Early data indicates that the infection rate is higher than that measured for another virulent coronavirus called SARS in 2002 and 2019.

Spreading of Coronavirus compared to SARS

Epidemiologists have confirmed the source of the new coronavirus as a wild animal market in the Chinese city of Wuhan where vendors sell dozens of carcasses and live animals including bats, rats, ostriches, crocodiles and hedgehogs. The Wuhan Institute of Virology has determined from patient samples that there is a 96% match to bat coronavirus. The SARS coronavirus outbreaks of 2002 also originated in bats and spread to humans via palm civets, cat-sized mammals sold in Chinese markets.

This latest form of the coronavirus causes severe acute respiratory illness manifested as coughing, fever and pneumonia similar to that caused by the variant of the coronavirus called “Middle East Respiratory Syndrome Coronavirus” (MERS-CoV) that was first described in September 2012. The MERS coronavirus epidemic resulted in a fatality rate of 49%. There is concern that, given the high infection rate, the new virus may have a similarly high fatality rate, particularly among those with compromised immune systems.

Dozens of people in several US cities have been infected principally by exposure to travelers from Asia. Health authorities in major cities like Los Angeles, San Francisco, Atlanta, Seattle, New York are screening airline travelers. Over 100 people in 26 states have been investigated and are being monitored for the virus. The expanding outbreak has sparked concerns at schools and universities across the country that have exchange programs with China. The CDC confirms that there is no vaccine available and recommends routine sanitary precautions to minimize the risk of infection.

Risk of infection is highest in densely populated cities, public areas and transportations centers where the airborne virus can become concentrated. Of particular risk are public rest rooms.

MERS transmission has been confirmed by inhaling aerosolized contaminated stool when flushing an open toilet. Aerosols persist in air for extended periods of time. Travelers and health care workers are at the highest risk.

Disruptive, FDA Approved Technology Can Help Minimize Viral Infection Risk

HGI Industries has developed a range of innovative sanitizing devices (Odorox® line of products) that are powered by high energy ultraviolet photochemistry, just like the action of the sun. These devices kill 99.99% of viruses, bacteria, mold and other pathogens in air, on surfaces and fabrics safely, in areas as small as an office or as large as hundreds of thousands of square meters (millions of square feet). HGI’s proprietary technology sanitizes by generating effective levels of atmospheric hydroxyl radicals, nature’s powerful atmospheric sanitizing oxidant.

Airborne hydroxyls are the perfect sanitizing agent. They react with a broader range of chemicals and are over one million times faster than ozone, bleach or other sanitizing agents. They react so fast that they are consumed within a few seconds, so they never accumulate. The cascade of organic peroxy and oxy sanitizing compounds formed also react very rapidly. Volatile organic by-products are rapidly decomposed as they are recycled through the device. Indoor environments are rapidly depleted of natural hydroxyls and build up unhealthy levels of chemicals, bacteria and viruses. Odorox® technology eliminates this build-up and restores nature’s safe balance indoors.

Atmospheric hydroxyl radicals (hydroxyls) are continuously produced by the action of the sun’s ultraviolet energy on oxygen and water in our atmosphere. There are, on average, two (2) million hydroxyls in each cubic centimeter of ambient outdoor air during daylight hours.

(D. E. Heard, “Analytical Techniques for Atmospheric Measurement”, Blackwell Publishing, 2006 – professor at the University of Leeds, UK). They keep air safe to breathe by decomposing natural and man-made pollutants and killing microorganisms. They sanitize air and surfaces by a natural process called lysing, where the hydroxyls react chemically with the lipids, protein carbohydrates and other organic chemicals in the cell wall and membranes of bacteria, viruses and other pathogens and disrupt their structure. The interior contents of the cells leak and the organism is destroyed. The mechanism for killing microorganisms is not biological, so the bacteria or viruses cannot develop any form of immunity.

Odorox® measured kill rates across a broad range of microorganisms on hard and porous surfaces and in air are consistently over 99.9%. Kill rates for aerosolized microorganisms are exceptionally high in the measured range of 4-5 log (99.99 to 99.999%) within several hours, as shown below from a study of the Odorox® MDU/Rx™ device presented to the FDA. This is particularly effective for the spread of viral disease as the main vector for transmission is inhalation of aerosolized virus.

Germicidal ultraviolet (UV-C) lights have been used for years to sanitize surfaces. UV-C lights have insufficient power to generate hydroxyls, whose formation requires higher energy UV energy. UV-C lights are only able to sanitize surfaces and biologicals within a few inches of their source and only when there is sufficient exposure time achieved by low flow rates. They are ineffective sanitizing air that circulates rapidly past their source and do not sanitize surfaces.

HGI’s Odorox® UV technology is unique: it is completely different from germicidal UV-C technology. Odorox® devices generate more intense and high energy UV radiation within a patented reflection chamber. Different models are customized for specified applications and volumes of space to ensure that hydroxyl levels match safe levels found in nature. Odorox® devices have received the ETL safety mark and the MDU/Rx™ model has been approved by the FDA for use in occupied spaces in medical facilities (510k #133800, 2014).

Odorox® portable devices can treat rooms from 27 to 540 square meters (300 to 6,000 square feet), either as standalone units or by integrating into existing heating and ventilation systems. Odorox® commercial devices are designed to treat large spaces - up to thousands of cubic feet

- and feature integrated, interactive process controls and sensors that measure and control the levels of sanitizing oxidants ensuring consistent, safe levels.

HGI’s Odorox® devices are manufactured in the United States. HGI can rapidly design and implement custom solutions that effectively treat public places at risk of coronavirus contamination and propagation. HGI can help authorities to rapidly put in place solutions that sanitize the air and surfaces in hospitals, airports, train stations, schools, universities, health clinics and other public places.

Benefits of Odorox Technology, Testimonials from our Customers

I would like to share the experience my family has had since bringing an Odorox Slim Line machine in to our apartment.

Please allow me to start by providing some background information. My daughter, who is 6, and I live in a 900 sq ft apartment in a 24 unit building in north Bismarck. We have lived there for over 5 years. My daughter has many health issues including chronic constipation, reflux, sinus issues and her IGG subclass II is low (basic immune deficiency).

Since bringing the Odorox unit in to our home in January, we have had our healthiest winter ever. In the past she has suffered from repeat sinus infections, often times each lasting more than one month. Prior to starting the Odorox Machine she had been fighting the same infection for over three months. We tried three separate rounds of oral antibiotics, an IVIG infusion and IV antibiotics and saw little if any results. Two weeks after instaiing the machine, her congestion was gone and has not returned. Her only infection since was an ear infection. This in itself is nothing sh01i of amazing. She has never gone this long without being placed on some so1i of medicine. We tried allergy medicines, antibiotics (oral and iv), ENT involvement, removed her tonsils and adenoids and nothing provided her with any relief. We also did both skin and blood testing for allergies, both of which came back negative. She herself has noticed the difference and comments on all of the different things she can now smell (flowers, lotions, soaps).

I almost need to mention that I am surprised how well this little machine controls odors.
I can no longer smell what other people in the building are cooking or if they are smoking.

I am truly amazed at the difference this machine has made. I will admit I was highly skeptical that this "magic machine" would do anything for us. In fact, I have even tried shutting the machine off for three days, only to tum it back on as her congestion was returning. I am sold as to the effectiveness and validity of this machine.

PuroClean of Tampa Bay has had the opportunity to work with a hydroxyl generator that we purchased from Tom McArdle. We have used it with fires, mold damage, and smoke odor removal.

The technology has really added to our "tool set" and has worked very successfully to improve the outcomes of our emergency cleanups.

But, even more, it has been a privilege to work with Tom and Michael McArdle. They are tremendously responsive and supportive to our business needs. Time and time again they have gone "over and above" to help us get the job done more quickly with exceptional results. Soon after we purchased our first Odorox generator, we used it in a condo where one of the owners had been a heavy smoker for over 15 years. Unfortunately, the owner had painted over the nicotine stains and the odor on their walls, thereby, locking in the smoke odor. When our one machine could not clean it, Tom and Mike brought 3 more machines to get rid of the smoke odor completely. In addition, they came out daily to the condo to check how it was working and kept following up to see what else they could do.

Both Mike and Tom are exceptional business colleagues. We look forward to working with them, and their technology, long into the future. If any customers would like to contact us to discuss the product in more detail, Ali and I would be happy to speak with potential clients.
