COUNTDOWN activities set across five major themes

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
