The effects of isolation strategies and diagnostic rate on R
. Basic reproduction number as a function of the combined effect of the level of isolation effectiveness and the diagnostic rate. Epidemiological mean parameter values for EVD are shown in Table 1. The mean time from symptoms onset to diagnosis (γ
a0) is varied from one to 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. The baseline value of R0 is set at 1.8. EVD, Ebola virus disease; R0, basic reproduction number.
