PHU 006: Contact Tracing - What, Why, How

Contact tracing is one of the cornerstone of infectious disease outbreak control.

In this episode, we'll unpack the What, Why, and How of Contact Tracing. We'll also discuss the factors that determine the extent of contact tracing and draw examples from COVID-19 as well as dengue fever.

Concepts from PHU 002: Epidemiological Triad of Disease Causation will be used here as well (here https://www.buzzsprout.com/1729639/episodes/8208709 )
