Protocol for Selection of Sentinel Sites for Schistosomiasis & Soil Transmitted Helminths and Annual Sentinel Site Surveillance for eSwatini

11 August 2023

This protocol is developed in the context of two outstanding challenges for the schistosomiasis Global community which are currently being addressed by a WHO constituted Strategic and Technical Advisory Group (STAG) for schistosomiasis: 

  1. Need to redefine the implementation unit (IU) which is by default set at a Districtlevel (there is an ambiguity in the size of Districts and in IUs which leads to implicit complications in later drug allocation as the focal nature of schistosomiasis is ignored)
  2. Need to resolve the ambiguity/lack of clarity over definition of an ‘ecological zone’.
