Correction to: Health Care Manag Sci (2020)10.1007/s10729-020-09526-0The original version of this article unfortunately contained a mistake in the equation and reference. Thus, this erratum is presented to correct the errors.In Chang et al. [1], eq. (12) was written asThis equation should be stated asThese expressions are not identical because the density being integrated is improper — the integrand is the probability density for the time to isolation, but it is possible that an infection is never detected (that is, it is possible that T is infinite).All numerical calculations in the paper are correct, and the associated app (https://jtwchang.shinyapps.io/testing/) does compute Pr{T > a} properly.
