In endemic communities with Schistosoma spp. prevalence of 10% or higher, WHO recommends annual preventive chemotherapy with praziquantel in a single dose for ≥ 75% up to 100% of pregnant women after the first trimester, and non-pregnant adolescent girls and women of reproductive age, including postpartum and/or lactating women, to control schistosomiasis morbidity and move towards eliminating the disease as a public health problem.
