3. ICST2 in Ghana
Expanded access to MDA (with follow-ups) & local WASH assessment with water contact behaviours
Three communities peri-urban areas in Weija:
Tomefa, Adakkope-Togokope and Manhaem
Parasitological (with molecular diagnostics) and epidemiological surveys conducted by household
~750 individuals participating in this in-depth study

4. Multisector actions needed to support chemotherapy
No complete coverage (with consecutive challenges)
Vulnerable groups left out and inequities arise
PZQ active on adult worms, juveniles tolerant
Treatment does not always fully clear all worms
Issue of re-infection due to contaminated environment
Adverse events can result in treatment rejections

5. WASH and SCH SCH is a disease of poor sanitation and water exposure(s)
Targets both sides of the coin: exposure and contamination
Potential of long-term behavioural changes
However
It requires a considerable investment in time and money
Hard to monitor its direct effects and longer term sustainment
Does not deal with spread of SCH via movement of people
