Understanding the Feasibility to Implement Schistosomiasis Elimination Project Under China-Zimbabwe Cooperation: A Pilot Study Protocol.

Background: Schistosomiasis is one of the major neglected tropical diseases in Africa, accounting for approximately 90% of the global burden. In Zimbabwe, Schistosoma haematobium and S. mansoni infections are endemic. Although mass drug administration has been carried out among school-aged children, other interventions at the national level remain incomplete. China has established a public health cooperation mechanism with African countries targeting schistosomiasis and other infectious diseases. This study aims to conduct a pilot study to provide a methodological reference for large-scale surveys in similar settings.

Method: This pilot study served as an entry point for China-Africa cooperation in schistosomiasis control. A combination of cross-sectional studies and snail surveys was used. The survey was carried out in 14 villages of Chevakadzi ward in Zimbabwe. Households were selected through simple random sampling for the study. Fecal and urine samples were tested in the laboratory to diagnose schistosomiasis. Meanwhile, a capacity and needs assessment was conducted to understand the current situation of local disease control strategies.

Discussion: This study is expected to obtain important epidemiological information and indicators regarding the transmission of schistosomiasis at the sub-district level, providing a basis for judging the feasibility and practicality of large-scale China-Zimbabwe cooperation investments. The research results will also offer references for policy-making and the update of prevention and control strategies, contributing to schistosomiasis control in Zimbabwe. However, the study has limitations such as limited funding and difficulties in cross-border drug registration.
