From: Transmission dynamics and control of Ebola virus disease (EVD): a review
The effects of isolation strategies on R 0 . Basic reproduction number as a function of level of isolation effectiveness in health care settings for three different baseline values of R 0: 1.3, 1.5 and 1.8. Epidemiological parameter values for EVD are shown in Table 1. The mean time from symptoms onset to diagnosis (γ a0) is assumed to be three days. The isolation effectiveness is given by 100*(1-l 0) where l 0 is the relative infectiousness of infectious individuals in health care settings. Baseline values of R0 are calibrated by adjusting the transmission rate β to achieve a given R0. EVD, Ebola virus disease; R0, basic reproduction number. Three lines represent results for three baseline values of R 0: 1.3, 1.5 and 1.8.
