Figure 2From: Risk of using logistic regression to illustrate exposure-response relationship of infectious diseases Simulated infections among 100,000 enclosed individuals. Initial prevalence 1% and infectivity rate 2% were set. During an incubation period, the number of persons (including infected and non-infected) whom each individual could contact was assumed to be negative binomial (p = 0.1, r = 1). The model was paused when it reached a targeted prevalence (10%, 20%, 30% and 40%).Back to article page
