Safely reopening school buildings is achievable with masking and proper air ventilation and filtration to combat potential airborne coronavirus transmission, according to a Harvard health expert.

The state has offered limited guidance to districts on how to address the issue, and experts say there's no one answer to the challenge — in part because every school has its own issues.

In the context of potential aerosol spread of SARS-CoV-2 infection, this Viewpoint argues for use of upper-room germicidal UV (GUV) fixtures as a means to disinfect circulating air and prevent spread of COVID-19 and other infections in health care settings.

Disinfectant dispersed from HVAC systems. Natural catalytic converter inserted into the ducts of an HVAC system. This new device converts H2O and O2 in the air into hydrogen peroxide (H2O2). The device uses a multi-wavelength ultraviolet light to illuminate target surfaces consisting of a honeycomb matrix treated with photocatalytic coating consisting of titanium oxide (TiO2) and other reactive metals added to enhance the overall catalytic effect. When inserted into the ducts of the HVAC system the device reacts with water molecules in humidity to continuously create predominately H2O2 molecules which exit the duct and disperse throughout the targeted area safely covering the surfaces of occupied rooms

The elimination of pathogenic bacteria is a key part of contamination control. However, many disinfectants are either not available in vapor form or they are harmful to users. A new ‘breathable mist’ offers a solution.

The Denver Broncos circulated a video of their football team getting doused by a "sanitizing" mist.

Viral diseases can spread through a variety of routes including aerosols. Yet, limited data are available on the efficacy of aerosolized chemicals to reduce viral loads in the air. Bacteriophages (phages) are often used as surrogates for hazardous viruses ...

Researchers in the Biomedical Engineering Department at Binghamton University studied how a certain type of ultraviolet light, UV-C, can kill viruses like coronavirus.

Qantas used Viraclean, a hospital-grade disinfectant, while Korean Air opted for MD-125. That’s a diluted version of D-125, a cleaning solution made by Microgen and used in industries from health care to poultry farming.

***2011 {Importantly, C difficile spores. Zimek fogger used to disperse EPA-registered disinfectants. User instructions needed. Most surfaces in patient rooms are non-porous.

In situ experiments indicate that the hydrogen peroxide dry-mist disinfection system is significantly more effective than 0.5% sodium hypochlorite solution at eradicating C. difficile spores and might represent a new alternative for disinfecting the rooms of patients with C. difficile infection.

Disinfection professional today are generally concerned with what percentage of a given germ is killed by a particular process or disinfectant. The highest percentage that is generally used is 99.9999%. In scientific research papers, this percentage is written as “ a 6 log10 reduction”, but in medical shorthand it’s known as “a greater-than 6-log reduction” …

May 2020. {Circulating wind ultraviolet air disinfector.} At present, the route of transmission of SARS-CoV-2 is still controversial, but the major route of the COVID-19 to rapidly spread through indoor environments, is caused by the airborne route of the virus carriers. At the same time, when patients with SARS-CoV-2 go to see a doctor, their bodies and clothing may be contaminated with viruses. The negative pressure diagnosis room may reduce the spread of the virus, but the number of negative pressure diagnosis rooms is very scarce. Our proposal is to use a circulating wind ultraviolet air disinfector as an additional indoor protection measure, to reduce the risk of airborne transmission of the COVID-19.

SUMMARY: A study has been made of the effectiveness of an Ibcol-triethylene glycol mixture for either atmospheric or surface disinfection in various types of poultry premises. Only a moderate bactericidal action was obtained with atmospheric disinfection using E. coli as the test organism. With a stronger mixture, a complete kill was obtained for surface disinfection with overnight exposure but the reduction in numbers of the test organisms with 30 min exposure did not exceed 75% in any experiment. Very satisfactory results were obtained with a formalin-water aerosol.

Ozone, available chlorine, quaternary ammonium salt, glutaraldehyde, and mixed disinfectant. he concentrations of airborne aerobic bacteria in the empty broiler houses after application of different disinfectants were significantly reduced compared to a house untreated with disinfectant (P < 0.05 or P < 0.01), and the number of inhalable particles of airborne aerobic bacteria sharply decreased after disinfection of empty poultry houses.

“Quaternary ammonium compounds were the most sensible solution for large area shipboard use, because they can effectively deactivate the virus by destroying its protein membrane,” Wynne said. “There are other chemicals that can be used to deactivate the virus, but they would be more corrosively aggressive to a ship’s delicate ecosystem."

2008. Clostridium difficile causes serious healthcare-associated infections. Infection control is difficult, due in part to environmental contamination with C. difficile spores. These spores are relatively resistant to cleaning and disinfection. The activity of a dry mist hydrogen peroxide decontamination …

Bio-hydrox is a non-toxic chemically-based advanced oxidation agent for high yield production of hydroxyl radicals, superoxide, singlet oxygen, and hydroperoxide anion among other reactive oxygen species. They work in synergy and deliver more oxidation potential than each specie alone (2.8 V to 2.9 V). It is 100% soluble and is able to oxidize most microorganisms instantaneously. It is breathable when low concentrations of dilutions in water are aerosolized. It is a great candidate to use with commercial sprayers, foggers and nebulizers for sanitation control of large spaces. It destroys bi...

Aerial misting in the presence of animals.Spraying a fine disinfectant mist in poultry housing can help reduce cross infection and prevent secondary infection during outbreaks of respiratory and other diseases. Virkon™ S can be misted in the presence of poultry at a dilution rate of 1:200 (0.5%).
