Developing environmental sampling as a method for monitoring SARS-CoV-2 in congregate settings

About the CUBE study

CUBE Study Info-graphic

  • The COVID-19 in the Urban Built Environment (CUBE) project seeks to develop environmental sampling as a spatially-resolved method for monitoring COVID-19 in congregate settings such as long-term care homes (LTC), universities, public schools, and daycares.
  • We collect samples by swabbing floors; then, the swabs are tested for COVID-19 using an RT-qPCR assay developed by DNA Genotek and/or a novel CRISPR-based device.
  • Currently, we are focused on facilities located in Toronto, Ottawa, and Sault Ste. Marie.


Study Locations

Our research team is currently monitoring 32 buildings in Toronto, Ottawa, and Sault Ste. Marie, including 10 long-term care homes, 13 schools and day-cares, and 6 university buildings. Click any city to expand.

We swab floors to pick up any SARS-CoV-2 RNA (the genetic material of the virus) that we can then detect using laboratory-based genetic methods. The aim of our study is to develop this technique as a means to monitor the presence of SARS-CoV-2 in congregate settings (e.g. schools, daycares, long-term care homes, workplaces, etc.).

Most facilities are swabbed once or twice weekly for a number of months.

Study coordinators will review results with site leads during the course of the study. Results of the analysis will be made publicly available when the study is complete.

The current scientific consensus is that COVID-19 is mainly transmitted through aerosols. It is highly unlikely for an individual to become infected by COVID-19 directly from floors.

Our research team has members affliated with The Ottawa Hospital, Children’s Hospital of Eastern Ontario, Mt. Sinai Hospital, University of Ottawa, Carleton University, University of Toronto, University of Waterloo, and DNA Genotek.

The CUBE study has received funding from CIHR, NSERC, The Ottawa Hospital Academic Medical Organization (TOHAMO), University of Ottawa, Carleton University, and DNA Genotek.
