MORBID: Morbidity Operational Research for Bilharziasis Implementation Decisions (Pilot)

A pilot study to identify meaningful and measurable targets for detecting the control of schistosomiasis-related morbidity in Africa. The overall study is designed to answer the following primary evaluation questions:

  • What are the infection levels of Schistosoma mansoni and S. haematobium below which there is little, or no, detectable schistosomiasis-associated morbidity?
  • What are the optimal morbidity markers for S. mansoni and S. haematobium?
  • What are the optimal species-specific morbidity goals for which schistosomiasis control programs should be aiming?


Sample size: 13 500
Implementation partner(s): Safe Water and AIDS Project (SWAP)
WHO Region: AFRO

Sample size: 13 500

The pilot study will be conducted in Malawi (endemic for S. haematobium) and Kenya (endemic for S. mansoni) based on previous experience working in these areas and confidence in their ability to carry out the work.
