Canadian Plant Implements Nasal Therapy to Fight COVID-19

Innovative strides in workplace safety amid the COVID-19 pandemic are making headlines, as a new study from Canada showcases the effectiveness of nasal photodisinfection therapy (aPDT) in significantly reducing viral transmission in high-risk environments. This pioneering approach, which combines a light-sensitive liquid and non-thermal red light to kill pathogens, has been deployed with promising results in a food processing plant.

The study, led by Dr. Richard Rusk of the University of Manitoba and Judy Hodge from Katrime Integrated Health, and published in the Public Health in Practice journal, reveals how aPDT, previously used in Canadian hospitals since 2011, can be an effective addition to pandemic safety measures in industrial settings.

During the peak of the pandemic, the food processing plant employing this technology reported much lower COVID-19 positivity rates among its workers compared to regional averages. This significant difference underscores the potential of aPDT as a critical tool in curbing viral spread, especially in settings where close contact is common.

The introduction of aPDT to the plant’s safety protocol included a comprehensive suite of measures such as enhanced sick leave policies, strict health screenings, and social distancing practices. Together, these measures fostered a high compliance rate with the weekly aPDT treatments, which the study notes as a key factor in the success of the initiative.

Notably, the safety assessments of aPDT indicated no serious adverse effects, bolstering its profile as a safe and effective method for reducing workplace transmission of COVID-19. This aspect is crucial for ensuring worker acceptance and adherence to new health interventions.

“The deployment of aPDT not only minimizes immediate risks associated with COVID-19 but also bolsters overall public health during high transmission periods,” Dr.  Rusk highlighted, suggesting that the adoption of such innovative treatments could play a significant role in future pandemic responses across various industries.

Dr. Rusk also emphasized the broader community impact of the findings. “Implementing aPDT in the workplace has shown not just a decrease in the infection rates among workers, but it has also contributed to the overall safety of the community. It’s a testament to how focused interventions can lead to substantial public health benefits,” said Dr.  Rusk.

These findings open the door for further research and application of aPDT in different settings, potentially offering a new standard for infectious disease prevention in workplaces worldwide.
