Real-time Estimates in Early Detection of SARS
Figure 2. Average expectation of the temporal pattern of Rt after implementation of control measures according to the day T of the last observation. A) Completely effective control measures. B) Limited control measures. Simulation values of R are also given: before day 20, R = 3; after day 20 R = 0 (A) and R = 0.7 (B). The gray zone indicates that R is <1. Information that the average expectation of R has passed <1 was obtained 9 (A) and 12 (B) days after control measures were implemented.
