From the Document: "COVIDTracer is a spreadsheet-based tool that allows state- and local-level public health officials and policy makers to compare three different contact tracing/monitoring strategies. The tool allows you to vary estimates of the potential effectiveness of each strategy, the average number of contacts per case, and the time needed for case interviews and contact follow-up activities. Once you have entered such information, COVIDTracer provides you with estimates of the number of personnel needed to conduct case investigations, contact tracing, and case and contact monitoring. You can then compare the potential effectiveness of each of these three strategies to a baseline situation of continued social-distancing type interventions that have a user-defined level of effectiveness. To use the COVIDTracer tool in your local jurisdiction, you first define the population, the number of cases to date, and the cases in the past 14 days. You also enter an estimated number of contacts per case and expected number of hours per day that contact tracers would work. You can assess up to three case identification and contact tracing and monitoring strategies simultaneously and compare the impacts on the total number of COVID-19 [coronavirus disease 2019] cases for each strategy over the course of the pandemic versus a 'base case' social distancing scenario."
