UConn Keeping Air in Connecticut Classrooms Safe

 UConn Today

Several years of community service and real-world research of the cross-campus UConn Indoor Air Quality Initiative has led to the awarding of $11.5 million in state support to UConn to bring access to low-cost, do-it-yourself “Corsi-Rosenthal” air-purifiers to every individual public school classroom in Connecticut.

On October 22 the State Bond Commission in Connecticut approved funding for the UConn Indoor Air Quality Initiative to administer and implement the purchase of equipment and materials for the construction and installation of individual classroom air purifiers. The state funding awarded to UConn will be part of SAFE-CT: Supplemental Air Filtration for Education Supplemental under the Clean Air Equity Response Program.

“We are pleased to offer these inexpensive devices to all classrooms across Connecticut,” says the Director of the UConn Indoor Air Quality Initiative, Marina Creed, an APRN who also serves UConn Health as a neuroimmunology nurse practitioner.  “When schools, students, and teachers run one of these inside their classrooms it will reduce their exposure to viruses and bacteria, reducing the risk of disease transmission, meaning they are less likely to get sick.”

Creed adds, “Thank you to the Governor, Lieutenant Governor, and General Assembly for putting the health of our students and teachers first.”

Although these devices are created simply with just $60 of hardware store materials, they have been shown to be incredibly effective.  The EPA and UConn jointly tested the devices in the EPA’s large bioaerosol test chamber, and results showed that in just 60 minutes it effectively removes over 99 percent of airborne viruses including the virus that causes COVID-19. Plus, recently published collaborative research findings by UConn and Arizona State University also show that DIY air purifiers work better than commercial HEPA air cleaners for a fraction of the cost...

Inexpensive, do-it-yourself air cleaner that can be easily constructed out of a box fan and MERV-13 furnace filters.

 The Corsi-Rosenthal Cube (sometimes called a Comparetto Cube) is an inexpensive, do-it-yourself air cleaner that can be easily constructed out of a box fan and MERV-13 furnace filters. The Corsi-Rosenthal Cube can give whole-room air cleaning performance comparable to commercial HEPA air cleaners that are 10x or more the cost. Total cost is around $100USD ($130CAD)...

Schools Are Significant Sites of COVID Transmission


The school setting is an important site of SARS-CoV-2 transmission, new data suggest.

An analysis of surveillance data for almost 1000 exposures to SARS-CoV-2 found that students accounted for a higher proportion of infected individuals who caused onward transmission than did the public overall (46.2% vs 25%).

“Our analysis suggests that younger age groups were deeply involved in the spread of the infection,” wrote study author Stefano Merler, MSc, a fellow at the Bruno Kessler Foundation in Trento, Italy, and his coauthors. They added that “control programs targeting contexts responsible for most of the transmission could be effective in limiting the spread of the infection, including in educational settings.”

The data were published online Sept. 20 in Influenza and Other Respiratory Viruses.

A DIY air purifier that costs under $100 to make is taking America’s classrooms by storm [But not @mcps @mocoboe !!!]

Late last year, Shiven Taneja was a person in search of a solution. His community of Mississauga, in Ontario, was entering its fifth COVID wave and Omicron was a fearsome, fast-spreading variant–yet rapid tests were in short supply and the availability of booster shots severely limited. He wanted a way to reduce risk.

Taneja found a potential answer in the same place many of us look: online. Reading about a do-it-yourself air filtration system designed to reduce aerosol particulates, he realized he could construct such a model for his own home at a fraction of the cost of a commercial HEPA purifier. Taneja quickly offered to build similar systems for others in his community at cost–and the requests came pouring in. A DIY solution to filtering the air had suddenly grown legs.

“My family’s living room became a warehouse for storing filters and fans,” Taneja told me. Since December, he says, he has delivered scores of home-built filtration systems, primarily to seniors and the immunocompromised who might not be able to do so for themselves.

All this would be impressive under any circumstance. It’s slightly more so when you consider that Taneja is 15 years old. And as we move into what may well be the endemic phase of Covid, his solution is one that many others around the world are also finding...

Sure @MCPS this is all fine and dandy hand waving but where is the real commitment to air quality and monitoring, ventilation, and filtration?

IMPORTANT MESSAGE FROM THE MCPS SCHOOL SYSTEM MEDICAL OFFICER

Dear MCPS Community,

We are so excited to be back together next week for the new school year! As we return to shared spaces, the health and wellness of our students and staff remains a top priority. We have more tools, experience and knowledge than ever to help reduce the impact of COVID-19 in our school community. Here are some important things to know about vaccination, testing and masking as staff and students return to school:  

COVID-19 Vaccination Helps Our School Community

Vaccines are an important way to lower individual risk of severe complications from COVID-19 infection. A high vaccine coverage rate helps reduce the overall burden of COVID-19 on the school community and helps keep learning going, as individuals with milder symptoms will miss fewer school or work days. We continue to strongly recommend students receive all recommended COVID-19 vaccines and boosters for which they are eligible. At this time, COVID-19 vaccination is required for staff unless approved for a medical exemption. We will continue to provide opportunities for students, staff and family members to receive COVID-19 vaccines at after-school and weekend events.

Rapid Testing for COVID-19 for a Strong School Year Start

Montgomery County Public Schools (MCPS) is encouraging at-home rapid testing for COVID-19 as staff and students return to school. Testing is an important way to identify individuals actively positive for COVID-19 who should temporarily isolate in order to prevent further transmission and keep our school community as healthy as possible.  

End-of-summer activities, such as returning from travel or getting together with larger groups, can increase the risk of exposure to COVID-19. Staff and students may consider testing even after school begins, following Labor Day holiday travel or after higher-risk social events that may coincide with the start of the school year. Testing is not mandatory. We are depending on our staff and families to consider their exposure risk, and test and report positive results accordingly. 

Test kits will be available at schools, at the MCPS Annual Back-to-School Fair on Aug. 27, and upcoming school-based weekend vaccination clinics on Aug. 27 and Aug. 28. Free rapid test kits are also available to Montgomery County residents at most public library locations, or by mail for home delivery from the U.S. government. Only positive test results need to be reported using the MCPS COVID-19 Reporting Form. Individuals who have a positive COVID-19 test should report their positive result and follow CDC guidelines for isolation. 

Masking 

As of today, the CDC COVID-19 Community Risk Level for Montgomery County is “low.”  At this time, masking is not mandatory in MCPS buildings or buses in most situations. Health room staff actively engaged in patient care or anyone assisting with medical procedures must follow infection control guidelines from the DHHS and the CDC, including wearing a mask when required.   

In addition, masking may be temporarily required for individuals or groups, in certain circumstances:

  • A student develops symptoms of COVID-19 during the school day and presents to the health room for evaluation
  • A student has tested positive at school for COVID-19 and is awaiting pick-up
  • In outbreak situations, as an alternative to quarantine for exposed individuals who do not have symptoms of COVID-19
  • For students or staff recovering from COVID-19 who have completed at least five full days of isolation, and feel well enough to return to school or work. 

Recommendations and requirements for masking can be expected to change during the school year, as COVID-19 data trends and science change. For individuals who cannot safely mask, other prevention measures will be used. 

Please remember that all staff and students are supported in their decision to wear a mask for individual protection, at any risk level.  MCPS will continue to provide masks for staff and students for use during the school day.

The new school year is just around the corner! Let’s work together to keep our school community well, as we return with excitement, renewed purpose and joy.  

Sincerely,

Patricia Kapunan, M.D.
MCPS Medical Officer

How's the air quality in Quebec schools? Here's what we found


As fall approaches, the Montreal Gazette visited several everyday places to see how CO2 levels compare to those measured in classrooms.


...Teachers submitted readings higher than 4,000 ppm on six occasions, all from different schools. The highest reading, 4,941 ppm, was recorded in a private high school classroom in the Laurentians. The lowest, 406 ppm, was taken in a high school on the South Shore.

Drouin has urged the government to release the raw data behind the C02 measures it tracks, arguing that basing decisions on averages doesn’t make sense.

“If one afternoon, a classroom is at 4,000 ppm, it’s in that moment that you could be at risk of catching COVID,” Drouin said. “Of course, there will be peaks and valleys, but it’s the peaks that are most important. Because that’s when you’re breathing other people’s air.”..

How to build Corsi-Rosenthal Box to protect against COVID for under $100 #COVIDisAirborne

Life in many places has largely returned to a pre-pandemic normal. People are tired of masking and remaining socially distant, even though contagious COVID-19 variants show no signs of going away anytime soon.

With attitudes toward COVID-19 becoming increasingly lackadaisical, public health experts are touting ventilation as a less-intrusive way to stop tiny particles carrying the virus from traveling through the air. But uptake of better ventilation practices — which can range from expensive to unrealistic — has been slow.

Enter the Corsi-Rosenthal Box, a do-it-yourself air filtration system that has taken the internet by storm. Each box typically costs under $100 to make and is more effective than other, pricier options like High Efficiency Particulate Air filters.

The simple contraption consists of a box fan, four MERV13 furnace filters that can be purchased online or in store, some cardboard and strips of tape. It’s the brainchild of air quality researcher Richard Corsi, dean of engineering at the University of California, Davis, and Jim Rosenthal, CEO of Texas-based company Tex-Air Filters...

Benefits of clean indoor air in school classrooms...

Installing air filters in classrooms has surprisingly large educational benefits

$1,000 can raise a class’s test scores by as much as cutting class size by a third.

An emergency situation that turned out to be mostly a false alarm led a lot of schools in Los Angeles to install air filters, and something strange happened: Test scores went up. By a lot. And the gains were sustained in the subsequent year rather than fading away.

That’s what NYU’s Michael Gilraine finds in a new working paper titled “Air Filters, Pollution, and Student Achievement” that looks at the surprising consequences of the Aliso Canyon gas leak in 2015.

The impact of the air filters is strikingly large given what a simple change we’re talking about. The school district didn’t reengineer the school buildings or make dramatic education reforms; they just installed $700 commercially available filters that you could plug into any room in the country. But it’s consistent with a growing literature on the cognitive impact of air pollution, which finds that everyone from chess players to baseball umpires to workers in a pear-packing factory suffer deteriorations in performance when the air is more polluted.

If Gilraine’s result holds up to further scrutiny, he will have identified what’s probably the single most cost-effective education policy intervention — one that should have particularly large benefits for low-income children...

Kids need fresh air to learn. This is known. Fresh air improves cognitive function. This is known. Your kid’s classroom probably does not have fresh air, and easily could.

Biden Brings His Own Ventilation to @mcps High School #COVIDisAirborne #CO2

On Thursday, August 26, 2022, President Joe Biden held a rally in the gym of Richard Montgomery High School in Rockville.  Montgomery County is currently in a period of HIGH COVID-19 Transmission with a Positivity Rate of 11.65%. What's a President to do with a potential super spreader event?  Why, bring his own ventilation, of course!  

Take a look at the air handling units that were added to the outside of the Richard Montgomery High School gym for President Biden's rally.

How do MCPS students that use this gym year round get the same type of ventilation upgrade for their use of this space?  



Meanwhile, MCPS parents continue to advocate for the Board of Education to acknowledge that #COVIDisAirborne.  The President of the United States gets it, why doesn't the Board of Education get it?  

**So in 2022, @mcps takes a hard pass on ventilation/air purification upgrades but leans in on "respiratory etiquette"**
