- How has MBG been used so far within the context of trachoma elimination?
- What is required in order to run MBG?
- Can MBG be used to estimate prevalence in inaccessible EUs?

- Can MBG be used for islands in an archipelago community?
- Is it possible to use MBG for an entire country?
- Where is the funding coming from to support the research and the Tropical Data development?
- Is there any support available for health ministries interested in implementing MBG?

- How does MBG work in the context of trachoma elimination?
- Who chooses the covariates to be included in the model?
- Where are the covariate data sourced from?
- Is it possible to "borrow" data from a long distance away, or does MBG work better when districts are contiguous?
- Can data over 5 years old be used?
- Has ground-truthing been done already or is there a plan to do it to validate the outcome of MBG?
