Figures & data

Table 1. Individuals aged ≥1 year enumerated and examined in refugee settlements in Uganda during baseline trachoma surveys, April 2018–February 2020.

Table 2. Children aged 1–9 years with active (inflammatory) trachoma in refugee settlements in Uganda, April 2018–February 2020.

Figure 1. Prevalence of (a) trachomatous inflammation—follicular (TF) in 1–9-year-olds, and (b) trachomatous trichiasis (TT) unknown to the health system in ≥15-year-olds, in refugee settlements in Uganda, April 2018–February 2020. The definition of an evaluation unit in these surveys was all refugee settlements within a given district. Coloured symbols are positioned at the centroid of districts from which refugee settlements were sampled. The boundaries and names shown and the designations used on these maps do not imply the expression of any opinion whatsoever on the part of the authors, or the institutions with which they are affiliated, concerning the legal status of any country, territory, city or area or of its authorities, or concerning the delimitation of its frontiers or boundaries.
