Abstract

Although preventive chemotherapy has been instrumental in reducing schistosomiasis worldwide, serious 44
challenges remain. These include the omission of certain groups from mass drug administration campaigns, the 45
existence of persistent disease hotspots as well as the risk of recrudescent infections. Central to these challenges 46
is the fact that the currently prescribed diagnostic tools to establish the burden of infection lack sensitivity, 47
especially in low endemic settings, resulting in an underestimation of the true prevalence of active Schistosoma 48
infections. This necessitates a re-evaluation and possible adaptation of current WHO-recommended control 49
strategies. Recently, more targeted interventions and novel approaches have been employed, such as 50
establishing infection burden by precision mapping to provide high resolution spatial information that delineates 51
significant variations in schistosomiasis prevalence within a defined geographical area. Such information is 52
instrumental in guiding targeted intervention campaigns. However, the need for highly accurate diagnostic tools 53
in such strategies remains a crucial factor that is often neglected. The availability of highly sensitive diagnostic 54
tests also opens up the possibility of applying sample pooling strategies, to reduce control programme costs. To 55
achieve interruption of transmission and eventually elimination of schistosomiasis, better local targeting of 56
preventive chemotherapy in combination with utilising more sensitive diagnostic tools is vital.
