Fig. 7
Variability in country-specific timelines to lymphatic filariasis (LF) elimination in sub-Saharan Africa. Distributions of the calendar years of LF elimination are shown for 6 out of the 12 considered remedial intervention scenarios (see Table 2). Countries are depicted in the graphs ranked by the year of elimination. Note that some countries are able to meet elimination by 2020 under their current strategy, and so would not need consideration of alternative strategies (Egypt, Ghana, and Togo). The results are shown for MDA1 and MDA4 (a and b), Bi-MDA1 and Bi-MDA4 (c and d), and IDA1 and IDA4 (e and f) (see Table 2 for descriptions). The left panel plots are for the current coverages of MDA and VC, while the right panel ones are for optimal 80% coverages for both. The widths of the boxplots denote the 25th and 75th percentile values of the calendar years shown on the x-axis. The vertical lines indicate the year 2020 — the target year set for global LF elimination (red) and the continental-wide model-predicted median elimination year for each strategy (blue). The whiskers show the 90% confidence interval computed using the 5th and 95th percentile values
