Confidence in conclusions derived from pooled samples from multiple laboratories. (A) Probability to accurately conclude the assessed virus to possess moderate to high transmissibility (P of ≥50% among all transmission events). (B) Probability to accurately conclude the assessed virus to possess low transmissibility (P of ≤25% among all transmission events). Each laboratory was assumed to provide results from 4 donor-contact pairs at a 1:1 ratio; transmission in each pair is an independent event. Transmission events in contact ferrets (x axis) are defined as detection of infectious virus and seroconversion to the exposed virus.
