How do we know if COVID-19 contact tracing is any good?

Contact tracing has become one of the key responses to the pandemic, but how do we know if our systems are any good? Australian researchers say there are currently no global standards to assess and monitor contact tracing systems making it impossible to assess their performance or to compare them. So they set out to look at what performance indicators are being used. They found the current performance indicators were missing some elements such as being able to show that contact tracing interrupted transmission chains and that it led to a decline in infections. They say to properly evaluate contact tracing we should look at ten areas including human and financial resources, contact identification, testing and follow up, transmission chain interruption, and incidence reduction.
