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

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

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
