Fig. 4 — The relationship between R₀ and the prevalence of infection in pre-SAC and SAC after five rounds of treatment assuming two coverage levels for LF. a Assumed LF coverage levels are 0.4, 0.4 and 0.3 for pre-SAC, SAC and adults respectively. b Assumed LF coverage levels are 0.7, 0.7 and 0.6 for pre-SAC, SAC and adults respectively. The dotted vertical lines indicate the R₀ regions that match with the measured prevalence regions (blue: 5–15% prevalence; red: 20–30% prevalence)
