Fig. 2From: Preventing COVID-19 outbreaks through surveillance testing in healthcare facilities: a modelling studyIllustration of randomized disease state retention times (A) and random sample of 20 infectivity profiles (B). Distributions of retention times for different disease states (A) correspond to the best guess parameters extracted from literature. Each infectivity profile (B) describes the time course of infectiousness of one random individual. The individual profiles differ in their onsets and infectivity levelsBack to article page
