Global, Regional, and National Burden of Trachoma: Cross-Country Inequalities, 1990-2021, with Projections to 2040.

ABSTRACT:

Introduction

In this work, we aim to evaluate the trends and cross-country inequalities of the global trachoma burden from 1990 to 2021 and to project its burden to 2040.

Methods

This study was a systematic analysis of the Global Burden of Diseases Study (GBD) 2021. Estimates for the prevalence and disability-adjusted life-years (DALYs) of trachoma were extracted from the GBD 2021 database. Epidemiological characteristics of trachoma were reported at the global, regional, and national levels. Trend analysis, decomposition analysis, and health inequality analysis were used. The global trachoma burden was further projected to 2040 via Bayesian age-period-cohort analysis.

Results

Globally, 1,414,047 people were estimated to have trachoma in 2021, with an age-standardized
