Other approaches are not addressed. The manual is divided into two parts. The first part covers specifics designe...d for training TT surgeon candidates, and serves as a resource document. The trainer can elect to have trainees read the material directly, use this manual as a guide for creating a training presentation, or use it in other ways to assist in the training.

The second part is designed only for the trainers of the surgeon trainees and covers selection and final assessment of the trainees. more

The World Health Organization (WHO) endorses the use of population-based prevalence surveys for estimating the prevalence of trachoma. In general, the prevalence of TF in children aged 1–9 years and the prevalence of TT in adults aged ≥ 15 years are measured at the same time in any district bein...g surveyed. This was the approach of the Global Trachoma Mapping Project, which undertook baseline surveys in > 1500 districts worldwide in order to provide the data required to start interventions where needed.
The survey design recommended by WHO is a two-stage cluster random sample survey, which uses probability proportional to size sampling to select 20–30 villages, and random, systematic or quasi-random sampling to select 25–30 households in each of those villages. In most surveys, everyone aged ≥ 1 year living in selected households is examined. more
