Motivating school communities towards behavior change and local ownership: a gamification intervention to prevent trachoma at primary schools in southern Ethiopia.

BACKGROUND: Ethiopia alone carries 49% of the global burden of trachoma, associated with a lack of safe water, sanitation and hygiene (WASH) and poor health practices. The aim of this study was to examine whether gamification among schoolchildren and promotion of local ownership of school WASH is associated with healthy behaviors and WASH infrastructure improvements. METHODS: Application of the Accelerate gamification intervention for elimination of trachoma, with an emphasis on gamification among schoolchildren and community involvement in motivating face-washing, handwashing and functional use of latrines, was undertaken. RESULTS: The study was conducted over 9 mo in 223 rural schools from six districts within the intervention area, reaching 93 518 schoolchildren. At baseline, students were observed washing their hands after using latrines in 23 (10.3%) schools. This increased to 132 (59%) schools (p≤0.001) at follow-up. The number of latrines increased from 585 at baseline to 594 at follow-up (p=0.031). The availability of handwashing stations in schools increased from 31 (13.9%) with water access (8%) and soap (5%) to 155 (69.5%) schools with handwashing stations with water access in 153 (98.7%) (p<0.001) and soap in 121 (78%) (p<0.001). CONCLUSIONS: Motivational strategies such as gamification among schoolchildren and promotion of local ownership of school WASH may be associated with healthy behaviors and WASH infrastructure improvements.

Schistosomiasis Control in Ethiopia: The Role of Snail Mapping in Endemic Communities.

Introduction: Schistosomiasis, a neglected tropical disease (NTD), remains a public health problem in Ethiopia. Freshwater snails, acting as intermediate hosts, release cercariae, the infectious parasite, into the water, which penetrate human skin that encounters infested waters. The objective of this study was to map snail abundance along rivers and study its association with schistosomiasis infection in communities using these rivers. Materials and Methods: A cross-sectional study was carried out at 20 river sites in Mizan Aman city administration, Bench Sheko zone, South West Ethiopia Peoples (SWEP) region, Ethiopia, to study the distribution of host snails and transmission sites for intestinal schistosomiasis. This study used a quantitative database consisting of data on the prevalence of infected snails, the characteristics of rivers and riverbanks, and the prevalence of schistosomiasis in the community, based on stool samples collected from community members near the sampling sites. Results: Aquatic snails were found in 11 of the 20 sites sampled. A total of 598 snails was collected, including Biomphalaria pfeifferi, Biomphalaria sudanica, Radix natalensis and Bulinus globosus species; the most abundant species was Biomphalaria pfeifferi. Stool samples were collected from 206 community members from all 20 sites. Forty-one (19.9%) were positive for Schistosoma mansoni. A positive correlation was found between the presence of snails and positive stool samples (r = 0.60, p = 0.05) and between the presence of infected snails and the prevalence of infection (r = 0.64, p = 0.03). Locations with muddy riverbanks were associated with the presence of snails (r = 0.81, p < 0.001). Conclusions: These results emphasize the importance of mapping snails for the control of schistosomiasis by defining hotspots of infection and identifying factors associated with the presence of infected snails. The results support the need for a continuous mapping of snails and the introduction of snail control as a major element for the successful control of schistosomiasis in endemic communities.
