Work out contact tracing load instantly with clear inputs, formula shown and shareable results.
Multiplies daily cases by contacts per case and divides by tracer capacity to give the workforce needed to keep tracing current.

Within 48 to 72 hours of the index case's symptom onset for most respiratory infections.
