Backward Contact Tracing: An emerging approach for public health management of COVID-19

Public Health Ontario has released a knowledge product, Focus On: Backward Contact Tracing, that provides a conceptual overview of backward contact tracing (BCT) as an emerging approach for public health management of COVID-19. This document also provides operational considerations for public health units (PHUs) on how BCT can be included in their COVID-19 case and contact management.

BCT is a method of contact tracing which aims to find primary or source cases of COVID-19 and other cases that are linked to that source. 

PHO, in collaboration with the Kingston-Frontenac Lennox and Addington Health (KFL&A) Unit, has developed this webinar as an accompaniment to this BCT document. The webinar will help local public health units that are not currently using this approach implement BCT.

By the end of this session, participants will be able to: 

  • Define backward contact tracing
  • Describe how BCT has been applied in KFL&A’s public health experience
  • Discuss situations in which BCT may be most helpful and feasible for COVID-19 case and contact management
