While contact tracing is routinely performed to control STDs, TB, and other communicable diseases, local health departments have limited front-line workforce (e.g., epidemiologists, disease intervention staff, public health nurses) to support contact tracing at the scale and pace of COVID-19. The CDC provides resources for training and supplementing existing staff for ongoing and surge support.
For contact tracing to be effective, every diagnosed case must be investigated, which means the contact tracing workforce must be capable of responding quickly even during surges. Find the number of staff you’ll need using this calculator provided by public health organization Resolve to Save Lives, and review additional estimates below.
