Description | We have investigated the complex multi-host disease dynamics of Schistosoma spp., including the emergence of zoonotic parasitic hybrids, which remain largely unexplored in West Africa. We elucidated the role of wild small mammals as reservoir hosts of Schistosoma mansoni and accidental hosts of Schistosoma hybrids in endemic areas of Senegal. Our findings indicate that rodents may be an important local reservoir for zoonotic schistosomiasis in endemic areas of West Africa, amplifying transmission to humans and jeopardising public health campaigns for disease control. |
Exploitation Route | This project has the potential to inform and guide future national and international control activities and assist local communities in the fight against schistosomiasis. Our research aims to contribute to the major push to eliminate schistosomiasis as a public health problem as recently prioritized by the WHO NTD roadmap. In order to reach this goal, it is essential to identify wildlife reservoirs of schistosomiasis and the mechanisms of hybridization/introgression shaping Schistosoma spp. evolution in these hosts. Our results are of substantial applied importance by helping public health officials, policy makers, and veterinary agencies to identify the preventive measures to reduce transmission risk and to design guidelines for disease management. Better tailored policies should also lead to improved management with concurrent increase in animal health, which will in turn assist in lifting rural human populations out of poverty in both the short and the sustained longer term. |

Impact | As cited below - new WHO Roadmap and Guidelines made - the former published the latter pending - with the proposed outcomes: 'They have led to the 2030 Guidelines recommending that in communities near to the interruption of transmission, defined as having no autochthonous human cases reported for five years, WHO suggests a verification framework that, testing of animals (livestock and wildlife) be undertaken using improved diagnostic tests of high specificity and sensitivity. In addition, these observations have highlighted the need to tailor approaches to the control and elimination of schistosomiasis to the ecological context where animal hosts are considered in the epidemiology, highlighting the need to apply WASH principles to help control interspecies transmission - treatment of humans alone will not interrupt transmission where animal reservoirs exist'. Future assessment will evaluate how this has been implemented at national levels within disease endemic countries. |

Results and Impact | Development of Revised Guidelines for implementation of control and elimination of schistosomiasis and verification of interruption of transmission - Expert Advisor General scope and objectives Currently, there is no guidance available to evaluate the interruption of schistosomiasis transmission. The existing implementation guidelines are based mainly on expert opinion and need to be revised according to the available scientific evidence. The goal of this GDG meeting will be to provide evidence-based recommendations to countries in their efforts to control morbidity from schistosomiasis and eventually interrupt transmission. They will help countries to implement national schistosomiasis control programmes and to verify whether transmission of the disease has been interrupted in the country. |
