How Much Testing Does Your State Need To Suppress Its Outbreak?

The Harvard Global Health Institute estimated targets for how much testing each state needs to mitigate or suppress its outbreak through a strategy of testing, tracing and isolating positive cases and their contacts. New daily cases are provided as a marker of current outbreak size, and are 7-day averages.

Notes: These testing targets, from the Harvard Global Health Institute and the TTSI Collaborative, are based on estimates of how many new COVID-19 cases might exist on July 6 based on outbreak data as of June 29. Daily new cases and daily testing are averages of data reported June 23-29. Data quality varies by state.
