The optimal donor-dependent screening variables. The optimal inter-testing time for regular tests (D k ) and the optimal time between a regular test and an interim test (d k ) as a function of a donor’s class, where classes k=1,…,9 have stool production rates in the intervals (4.7−25.3,25.3−45.9,45.9−66.5,66.5−87.1,87.1−107.7,107.7−128.3,128.3−148.9,148.9−169.7,169.7−190.3) g/day
