CADTH is committed to supporting Canada’s health care decision-makers through this challenging and uncertain time.

Our COVID-19 Evidence Portal contains the latest COVID-19 information from CADTH and other respected organizations. Content is updated daily to reflect the rapidly changing and increasing international scientific evidence related to this disease.

The following is a summary of the most recent information posted to our COVID-19 portal.


Respirator Device Fit for Individuals With Facial Hair

  • This report looks at the evidence regarding facial hair and (medical) respirator devices.
  • At the time of the report, two studies were identified on this topic. The authors of the studies reported that as beard length increased, the additional facial hair was less likely to accommodate a properly fitted respirator device.
  • This report did not identify any recommendations on facial hair and respirator devices.

Ongoing Trials for Drugs in the Prevention and Treatment of COVID-19

  • This report provides information on ongoing randomized controlled trials of drugs being investigated to treat or prevent COVID-19.
  • It will be updated every 2 weeks.
  • Ongoing trials of vaccines and plasma-based therapies are addressed in separate CADTH reports.
