Fig. 5 — Changes in the model-derived estimate of prevalence of heavy infection (S. mansoni ≥400 epg; S. haematobium ≥50e/10 ml) with treatment with praziquantel. a and b S. mansoni areas; c and d S. haematobium areas. Note difference in y-axis scales. Data were collected annually. The lines linking the data points are included for illustrative purposes are not verified parasitologically. These lines assume a constant force of infection and assume 95 % efficacy of treatment for S. mansoni and 99 % efficacy of treatment for S. haematobium
