TradFest Temple Bar 2021

As Covid-19 spread around the world, live music events everywhere were canceled or postponed. TradFest Temple Bar, an annual live music festival celebrating Irish music and culture, reimagined their iconic event with the help of Novaerus air dis-infection technology from WellAir.

A live music festival reimagined for the COVID-19 era.

Every January, Dublin’s famed Temple Bar district erupts with music and joy, as TradFest Temple Bar — a five-day celebration of Irish music and culture — draws top bands and massive crowds to historic churches, castles, pubs, and other iconic venues.

TradFest Temple Bar 2020 beat the Covid-19 pandemic by mere weeks, wrapping up just before live music everywhere came to a screeching halt. When it came time to plan TradFest Temple Bar 2021, the virus was on its second rampage, and prospects for live performances had worsened. Science had established that SARS-CoV-2 was airborne and that singing was especially risky.

Worldwide, music festivals were cancelled. But Martin Harte, CEO of The Temple Bar Company, the not-for-profit organiser of TradFest, wasn’t having it. After all, Tradfest, Ireland’s largest festival of traditional music, had run annually since 2005.

“I said, ‘No, the show must go on,’” recalls Harte. And it did. In the throes of the pandemic, TradFest delighted fans with a scarce commodity: music performed live and indoors.

Novaerus Medical-Grade Air Dis-Infection Technology

The audiences weren’t live, of course; the concerts were streamed. But the artists performed within the storied, stone walls of Dublin Castle, a fortress that dates back to 1230 and, just for TradFest 2021, was outfitted with Novaerus medical-grade air dis-infection technology from WellAir. Over five days, some 50 musicians and crew members gathered to rehearse, pose for photos, and perform amidst rococo ceilings and portraits of Irish viceroys — all the while breathing air cleaned by sleek, white Novaerus devices out of camera range.

The devices featured prominently in TradFest’s safety proposal to the Office of Public Works, the government agency that operates Dublin Castle. “The Novaerus devices helped us hugely in securing approval to use the castle,” says Harte.

Of course, it wasn’t just government authorities that needed convincing; the performers and crew — ages 18 to 80, emerging artists and folk legends alike — had to feel protected. “Novaerus devices made the difference in getting people to agree to perform,” Harte says. During the event, artists, and staff noted the quiet presence of Novaerus devices, says Harte. “I pointed out that right on the back of the machine, it says ‘infection control device.’ People felt reassured and relaxed.”

The technology helped foster a sense of normalcy in decidedly abnormal times. “It was a lovely and very hopeful atmosphere,” says Deirdre Devitt of The McGreals Group, a TradFest sponsor and Novaerus distributor. “You could feel the sheer joy the performers and crew were feeling.”

The festival proved to be entirely Covid-free — “We had no illness, nothing,” reports Harte — while the same could not be said for the rest of Ireland. “During that week, Covid got out of control,” says Harte. “Three days after we finished shooting, Ireland closed down. Dublin Castle was possibly the safest space you could be in the whole country.”

When the pandemic struck, Harte knew nothing of Novaerus devices. He just knew he wanted TradFest 2021 to happen — somehow. “People need culture, and artists need work, and there was the commercial opportunity for us to sell tickets worldwide,” Harte says.

Harte delved into research on Covid-19 transmission and became convinced, early on, that the disease was largely spread via aerosol. He even read up on tuberculosis, another disease that was initially considered transmissible only via large droplets but was ultimately proven to be spread by microscopic viral particles. Harte noticed, too, that businesses were scrambling to install plastic dividers and disinfect surfaces, disregarding the real threat: infectious aerosols. “I could see we were making the same mistakes with Covid that they made with TB,” Harte recalls.

Harte’s global search for a solution led him back home to Ireland, where WellAir’s Novaerus technology was being developed and manufactured for use in medical settings.

“Novaerus isn’t a hygiene product — it’s something you’ll find in an ICU, in a neonatal unit,” says Harte. “That was the level of care we wanted. Our brand is too strong and our audience and performers are too important to put them at risk.”

Reopening in the COVID-19 Era

Not only did Harte deploy Novaerus devices for TradFest but he also has encouraged bars and restaurants throughout Temple Bar, Dublin’s primary tourist district, to do the same. In fact, Harte won’t hold meetings in a room that is not continually cleaned by WellAir’s patented NanoStrike technology, which powers all Novaerus devices.

“I don’t feel comfortable breathing someone’s contaminated air,” he says. The public, he believes, is starting to feel the same way.

“When the world re-opens, people will make choices as to what bars and restaurants they’ll go into. And once people want it, you have to have it. Novaerus technology is like a fire extinguisher: You cannot safely run your business without it.”

Covid is here to stay in some shape or form, says Harte, “and we need to adapt. We’re not returning to normal any time soon.”

Yes, Covid-19 Aerosols Are Infectious, And More Dangerous than Droplets – Part 2

Read part one of this blog post here.

Infectious Aerosols: Small but Potent

Many Covid-19 precautions — plexiglass dividers, desks spaced 6 feet apart, reduced restaurant occupancy — are premised on the notion that large droplets, generated by sneezes and coughs, pose the greatest danger to vulnerable people.

In reality, the most dangerous droplets are the invisible ones, particularly those in the range of 2 μm to 3 μm.

Not only can aerosols hover for hours and travel across rooms, but they also carry more infectious virus than large droplets.

“Humans produce infectious aerosols in a wide range of particle sizes, but pathogens predominate in small particles,” explains Kevin Fennelly of the NIH.

This is true for influenza, SARS-CoV-2, and other respiratory viruses, says William Lindsley, PhD, a biochemical engineer with the U.S. Centers for Disease Control and Prevention.

“You see a lot more virus in small aerosols,” Lindsley told a panel at an international conference on the aerosol transmission of Covid-19.

This is because of where aerosols originate: in the lungs. Research shows the viral load of SARS-CoV-2 is higher in the lungs compared to the upper respiratory tract.

What makes aerosols so dangerous is that once inhaled, they can penetrate deeper into the lungs. For a patient to develop severe Covid-19 symptoms, such as pneumonia or acute respiratory distress syndrome, the virus must reach the lower airways, and only small aerosols can travel that far.

“We know that if the virus makes it down deeper into the respiratory system, fewer viruses are required to initiate infection, and this can also affect the severity of disease,” Marr reported at the international Covid-19 conference.

To those still sceptical that aerosol transmission is driving Covid-19 spread, NIH’s Fennelly responds: “There is no evidence to support the concept that most respiratory infections are associated with primarily large droplet transmission. In fact, small particle aerosols are the rule, rather than the exception, contrary to current guidelines.”

NanoStrike Technology: Fighting Aerosol Spread of Viruses

How can guidelines be updated to reflect the reality of aerosol transmission?

Healthcare facilities cannot simply rely on personal protective gear, hand hygiene, and cleaning protocols. And distancing protocols, whether implemented in nursing homes, offices, or pubs, are of limited use indoors; the 6-foot/2-metre rule does not stop aerosols from floating across a room.

With SARS-CoV-2 hovering, undetectable, what all indoor environments need is high-powered air dis-infection, such as Nanostrike technology from Novaerus.

Novaerus’ compact devices use a plasma field that obliterates pathogens at the molecular level, instantly rendering them inactive. The technology has been used in over 65 countries to help combat Covid-19, particularly in hospital operating rooms, intensive care units, emergency rooms, waiting rooms, and surgical theatres.

The Novaerus Defend 1050, cleared by the U.S. Food and Drug Administration as a 510(k) Class II medical device, has been proven in independent laboratory testing to filter out and inactivate a wide range of airborne viruses and bacteria.

Within 15 minutes, the Defend 1050 has demonstrated a 99.99% reduction of the MS2 bacteriophage RNA virus, an accepted surrogate for SARS-CoV-2. The device, like other Novaerus units, has shown similar efficacy with other airborne pathogens, including influenza, Clostridium difficile, Aspergillus, and surrogates for Measles virus, Tuberculosis and Methicillin-Resistant Staphylococcus Aureus (MRSA).

Upon obliterating pathogens, the Defend 1050, a portable, free-standing system, releases clean air back into the room. Unlike other technologies, which can pose risks to humans, Novaerus devices are safe for 24/7 use among the most vulnerable patients.

Though NanoStrike technology was designed for use in medical settings, Novaerus’ sleek, compact devices have also been installed in retail, hospitality, and office settings, from wine-tasting rooms to hotel lobbies, offering medical-grade protection to customers and staff alike.

From Measles to Covid-19

In 1982, one year after those seven American children contracted measles during a visit to the paediatrician, a similar outbreak occurred in another American paediatrics practice.

This time, three children contracted measles despite arriving at the doctor’s office more than an hour after the source patient had left the building.

And this time, instead of dismissing the incident as an outlier, scientists conceded that the conventional wisdom about measles likely had been wrong.

“Airborne transmission may occur more often than previously suspected,” a team of public-health physicians wrote in the Journal of the American Medical Association.

With regard to Covid-19, scientists have come to that conclusion more quickly. Now, building operators must make sure the precautions keep up with the science.

Covid-19 Aerosols Are Infectious, And More Dangerous than Droplets – Part 1

More and more evidence supports the case that Covid-19 Aerosols are infectious and more dangerous than droplets, in this blog post we take a look at how a similar debate was made around measles in the 1980s and how health officials reacted compared to how the health officials have reacted to the current Covid-19 pandemic.

In 1981, seven American children contracted measles during a visit to the same doctor’s office.

Three of the children had never crossed paths with the 12-year-old source patient. One child arrived at the office an hour after the infected boy had left.

The outbreak caused a stir. At the time, public-health authorities believed measles was transmitted via large respiratory droplets, the kind generated by phlegmy coughs, and required contact within about 1 meter of an infected person.

So ingrained was this belief that a major medical journal, Pediatrics, deemed the outbreak an outlier, concluding that for measles, “Infectious Aerosol spread is unusual.”

Of course, today we know the opposite is true. Microscopic measles particles can remain airborne and infectious for up to 2 hours and can drift far and wide. In one case, an infected athlete transmitted the disease to spectators 100 feet (30.5 meters) away. The notion that measles is primarily contracted through contact with large droplets, rather than via tiny, inhaled aerosols, has been thoroughly debunked.

One year into the Covid-19 pandemic, that same theory has been debunked with respect to SARS-CoV-2 transmission, though infection-control measures have lagged behind the science.

In one regard, the evidence supporting aerosol transmission for Covid-19 is actually stronger than it is for measles: Viable SARS-CoV-2 has been captured via air sampling, a feat that has yet to be achieved with the measles virus.

In fact, only one study, published in 2016, long after experts declared measles airborne, has captured measles RNA in the air — a study its authors called “the first study to directly detect evidence of airborne transmission of measles.” Yet in that study, testing in cell cultures failed to detect viable measles virus.

By contrast, at least six air-sampling studies have isolated SARS-CoV-2 RNA. And one, conducted at the University of Florida, proved SARS-CoV-2 viral particles — captured as far as 4.8 meters from a Covid-19 patient — were viable.

“If this isn’t a smoking gun, then I don’t know what is,” asserts Linsey Marr, PhD, a Virginia Tech aerosol scientist who was not involved in the study.

Marr calls the results “unambiguous evidence that there is infectious virus in aerosols.”

The Florida study, piled atop volumes of other evidence pointing to aerosol transmission, has intensified calls for more robust infection control indoors — in hospitals, nursing homes, dental practices, and retail establishments.

With ultra-contagious SARS-CoV-2 variants now surging globally, the stakes could not be higher.

“It is very clear that aerosols play a considerable role in the transmission of Covid-19 and that we are unlikely to prevail against this pandemic unless we acknowledge that fact,” asserts Justin Morganstern, M.D., a Canadian emergency physician, in an evidence review.

While physical distancing and masks remain important, Morganstern argues, “We should be looking at the extra precautions we can add to stem the spread of this disease.”

Foremost among these precautions should be air filtration and dis-infection, say experts, including Kevin Fennelly, M.D., of the U.S. National Institutes of Health.

At hospitals and nursing homes, infection-control protocols are based on “old data and inferences,” Fennelly asserts in The Lancet Respiratory Medicine. Droplet transmission is not driving the pandemic, he argues, and precautions should be updated to “account for the predominance of small particles within infectious aerosols.”

Covid-19 Aerosols are Infectious in the Air

At the pandemic’s outset, health authorities made the same assumption about SARS-CoV-2 that they’d made, erroneously, about measles in the 1980s and tuberculosis in the 1950s: that aerosol transmission, if it happened at all, was “probably very rare.”

But that assumption soon began to wither.

Quickly, it became clear that asymptomatic carriers were spreading Covid-19 in huge numbers, without sneezing or coughing.

What’s more, scientists identified outbreaks — on cruise ships and bus rides, at choir practices and ski resorts, in call centres, restaurants, and shopping malls — that could not be explained by surface or droplet transmission.

Strengthening the case for aerosol spread, scientists captured SARS-CoV-2 genetic material on surfaces that patients could not possibly have touched, such as air outlet vents and air-handling grates.

Even more compelling, coronavirus particles were captured in the air — above flushing toilets, in hospital nurses’ stations and changing rooms, in hallways outside patient rooms, and inside patient rooms beyond 6 feet from the patients.

Still, questions persisted: Was the RNA viable? Could the captured particles actually invade a cell, replicate, and trigger infection? Or were they inert, harmless fragments of genetic material?

The answer was elusive because aerosols, microscopic and fragile, are easily damaged by the air-sampling process.

But the University of Florida team used new, more sophisticated technology, preserving SARS-CoV-2 RNA captured in the air 15 feet from a Covid-19 patient. The genome sequence of the collected virus matched the sequence isolated from the patient.

The study, says lead researcher John Lednicky, PhD, proved “conclusively” that viable SARS-CoV-2 particles, small enough to be inhaled, can linger in the air and pose a risk to those in the vicinity.

The study squelched doubt that Covid-19 can spread — and readily — via aerosols.
