From: Vaccination or mass drug administration against schistosomiasis: a hypothetical cost-effectiveness modelling comparison

Parameter Value Reference
No. of human hosts in population, N 1000  
Baseline prevalence in SAC High-transmission setting, 65%; Moderate-transmission setting, 45% (Obtained by scaling the contact rate between human hosts and the reservoir)  
Age-dependent contact with reservoir Ages 0–4: 0.032; 5–9: 0.162; 10–14: 1.0; 15+: 0.05 [43]
Shape parameter α of Gamma distributed risk factor 0.24 [43]
Kato–Katz test aggregation parameter, k 0.87 [44, 45]
Exponential fecundity decay, z 0.0007/worm [23, 46]
Maximum fecundity, λ 0.14 egg counts/female worm [45, 47]
Average worm life-span 5.7 years [48]
Human demography Based on Kenya’s demographic profile [49]
