Table 1. Endemicity classes for implementation of SAFE based on trachomatous inflammation–follicular (TF) and trichiasis (TT).

TF Prevalence band	Classification	Implementation
<5%	Non-endemic	No need for implementation of AFE
≥5% and <10%	Hypo-endemic	Mapping, F and E can be applied, focal A
≥10% and <30%	Meso-endemic	AFE at district level (≥3 years then review)
≥30%	Hyper-endemic	AFE at district level (≥5 years then review)
