Forty per cent of COVID-19 deaths in Ontario have taken place in long-term care properties. Power and in some circumstances devastating outbreaks have additionally been reported in shelters, detention centres and group properties for adults with disabilities. Residents and employees have died, and 1000’s extra have been contaminated.
In these group amenities, termed “congregate settings” in Ontario, folks eat collectively, and bedrooms and loos are sometimes shared. Due to this, they’re very high-risk for buying airborne ailments.
It’s crucial that congregate settings obtain the perfect, most rigorous steering accessible from Public Well being Ontario (PHO). However that isn’t what is occurring. A key side of an infection prevention and management — indoor air high quality — has been omitted from PHO’s public, written COVID-19 steering particularly designed for these kind of amenities.
Sub-standard steering for congregate settings
Our staff, which incorporates researchers with experience in indoor air high quality, engineering, epidemiology, public well being and data translation, performed an in depth research of the general public, written steering PHO has produced particularly for establishments reminiscent of long-term care properties, shelters, group properties and correctional amenities. (The research is shared right here as a pre-print, and has been submitted to a journal for peer assessment.)
We discovered no references to air flow, HVAC (heating, air flow and air-con) methods, transportable air filters, rest room exhaust followers and even opening home windows. This contains PHO’s COVID-19 checklists for long-term care properties and congregate settings, which goal those that are accountable for facility well being and security.
Whereas our formal research concluded on the finish of October 2021, we’ve continued to discover steering on PHO’s web site. At the same time as outbreaks proceed in amenities reminiscent of long-term care properties and shelters, nothing a lot has modified, virtually two years into the COVID-19 pandemic.
The precautionary precept
THE CANADIAN PRESS/Nathan Denette
The 2003 SARS outbreak killed 44 folks in Ontario. In his 2006 report for the SARS Fee, Choose Archie Campbell emphasised one central level: Ontario’s public well being and health-care methods ought to reply to illness outbreaks utilizing the precautionary precept.
The precautionary precept means erring on the facet of warning. Should you’re undecided a security measure is critical, take it anyway, particularly if it may save lives. Specifically, Campbell pleaded with decision-makers to use the precautionary precept within the face of potential airborne transmission of a novel respiratory illness.
In 2008, PHO (then referred to as the Ontario Company for Well being Safety and Promotion) was established, partially to make sure that Ontario could be ready for future pandemics. PHO is remitted by provincial laws to supply scientific and technical recommendation within the face of infectious illness outbreaks. Additionally it is tasked with “evaluating the modes of transmission of febrile respiratory diseases.”
In different phrases, PHO is accountable for determining how respiratory viruses unfold, and serving to the province tackle transmission. The laws that created PHO additionally particularly duties it with contributing “to efforts to scale back well being inequities.”
Quick ahead virtually 15 years to the COVID-19 pandemic. Since mid-2020, physicians, scientists and engineers have been urging public well being decision-makers to handle airborne transmission of COVID-19. In July 2020, 239 scientists revealed a commentary within the journal Medical Infectious Illnesses, “advocating for the usage of preventive measures to mitigate this route of airborne transmission.”
In November 2020, physicians and engineers wrote an open letter to PHO and the federal government of Ontario, urging them to, “replace the province’s COVID-19 tips, laws and public communication to replicate the significance of air flow…”
In the meantime, peer-reviewed proof of airborne transmission piled up. Research documented airborne transmission in eating places, hospitals, motels and church buildings and demonstrated that individuals launch high-quality, virus-laden aerosols once they speak, sing, or just breathe.
On the identical time, scientists and engineers shared in depth details about measures with the potential to mitigate airborne transmission reminiscent of respirator-grade masks, air flow, filtration, rest room exhaust followers and upper-room ultraviolet disinfection.
Accountability and alter
As with responses to earlier well being crises, there’ll seemingly be an inquiry into the best way public well being and health-care authorities in Ontario approached airborne transmission through the COVID-19 pandemic. Its suggestions could also be much like these made by the SARS Fee 15 years in the past.
The distinction this time? First, the dimensions of dying. Over 12,000 folks have died in Ontario, lots of whom reside or work in the exact same congregate settings getting incomplete an infection prevention and management recommendation from PHO.
Second, the hope that one other retroactive inquiry can generate significant change. Whereas we don’t discourage an inquiry, because the proof generated by the SARS Fee is invaluable, it is not going to guarantee accountability.
As a substitute, it’s time to deal with broadcasting the suitable data far and broad. Fortunately, there are a lot of dependable sources of steering, together with the American Society of Heating, Refrigerating and Air-Conditioning Engineers and the Clear Air Crew.
It’s additionally time to discover regulatory and authorized mechanisms with the capability to carry PHO accountable to its legislated mandate.
Lastly, and whereas we try and mitigate the injury unfolding in actual time, it’s time to seed the beginnings of a brand new system: one which embraces the precautionary precept, values the well being and well-being of individuals dwelling and dealing in congregate settings, and treats each single preventable dying as a catastrophic failure.
