Although COVID-19 can be considered both an infectious disease and a respiratory disease, we recognize that many people are interested in all research pertaining to the global pandemic declared on March 11th, 2020 by the World Health Organization (WHO). The content below is the collective contributions of research, projects, and media from the teams of scientists at the CHEO Research Institute.

Research Projects

  1. SARS-CoV-2 Protein in Wastewater Mirrors COVID-19 Prevalence


    Here, we demonstrate the presence of SARS-CoV-2 structural proteins in wastewater using traditional immunoblotting and quantitate them from wastewater solids using an immuno-linked PCR method called Multiplex Paired-antibody Amplified Detection (MPAD). In this longitudinal study, we corrected for stochastic variability inherent to wastewater-based epidemiology using multiple fecal content protein biomarkers.

  2. Healthy movement behaviours in children and youth during the COVID-19 pandemic: Exploring the role of the neighbourhood environment Author links open overlay panel


    This paper explores patterns of increased/ decreased physical activity, sedentary and sleep behaviours among Canadian children and youth aged 5-17 years during the COVID-19 pandemic, and examines how these changes are associated with the built environment near residential locations.

  3. Quantitative analysis of SARS-CoV-2 RNA from wastewater solids in communities with low COVID-19 incidence and prevalence


    Can we find COVID-19 markers in the wastewater that will help predict outbreaks?

  4. Decontaminating N95 and SN95 masks with ultraviolet germicidal irradiation does not impair mask efficacy and safety


    Our findings suggest that further work in this area (or translation to a clinical setting) should use a cumulative UV-C dose of 40,000 J/m2 or greater, and confirm appropriate mask fit following decontamination.

  5. Decontamination Interventions for the Reuse of Surgical Mask Personal Protective Equipment: A Systematic Review


    There is limited evidence on the safety or efficacy of surgical mask decontamination. Given the heterogeneous methods used in studies to date, we are unable to draw conclusions on the most efficacious and safe intervention for decontaminating surgical masks.

  6. Canadian children’s and youth’s adherence to the 24-h movement guidelines during the COVID-19 pandemic: A decision tree analysis


    Our results show that specific characteristics interact to contribute to (non)adherence to the movement behavior recommendations. Results highlight the importance of targeting parents’ perceived capability for the promotion of children's and youth's movement behaviors during challenging times of the COVID-19 pandemic, paying particular attention to enhancing parental perceived capability to restrict screen time.

  7. Impact of the COVID-19 virus outbreak on movement and play behaviours of Canadian children and youth: a national survey


    This study provides evidence of immediate collateral consequences of the COVID-19 outbreak, demonstrating an adverse impact on the movement and play behaviours of Canadian children and youth. These findings can guide efforts to preserve and promote child health during the COVID-19 outbreak and crisis recovery period, and to inform strategies to mitigate potential harm during future pandemics.

  8. Seeking Normalcy as the Curve Flattens: Ethical Considerations for Pediatricians Managing Collateral Damage of Coronavirus Disease-2019


    Children have encountered and will continue to encounter unique challenges as the COVID-19 pandemic continues. We cannot ignore discrepancies in social determinants of health. Keeping families and communities safe and our patients healthy is no small task. But we have an opportunity, if we pay close attention to the vulnerabilities exposed by this pandemic, to make conditions better for children than before the pandemic began.

  9. New Data regarding decreased physical activity during the Global Pandemic


    The time spent in places associated with physical activity such as parks, beaches, and community gardens was down by 31%, and travel by public transport, which is also associated with physical activity, was down by 59%.

  10. Paediatric ethical issues during the COVID‐19 pandemic are not just about ventilator triage


    the COVID‐19 pandemic is creating many ethical challenges. One of the most difficult is for ethicists to focus on the issues that are likely to have the greatest impact. Ventilator allocation in a crisis situation is a deeply tragic choice that requires careful balancing of a number of values

  11. Efficacy and Safety of Disinfectants for Decontamination of N95 and SN95 Filtering Facepiece Respirators: A Systematic Review


    Aim:The objective of this review was to synthesize existing data on the effectiveness and safety of using disinfectants to decontaminate N95 FFR.

  12. Decontaminating N95 masks with Ultraviolet Germicidal Irradiation (UVGI) does not impair mask efficacy and safety: A Systematic Review


    Microwave irradiation and heat provides safe and effective decontamination options for N95 FFR reuse during critical shortages. However, autoclaving masks is not recommended by the evidence in this review. Any mask disinfected using these methods should be inspected for physical degradation before reuse.

  13. Researching COVID-19 Community Markers in Wastewater

    This is an active study.

  14. Natural Evolution of Serum Antibodies in Children and Adults with SARS-CoV-2 and Household Contacts.

    ACTIVE STUDY - The study will include children and adults with known COVID-19 to test households for antibodies. Results from this study will be essential to inform key decisions regarding the relaxation of physical distancing rules that impact children and their families.
