Purpose: Trachoma is the leading cause of infectious blindness worldwide. It is known to be highly corre- lated with poverty, limited access to health care ser- vices and water. In 2016 the WHO estimated that
110.000 people were suffering from active trachoma and 80.000 were severely visually impaired or blind as a result of trachoma: this study provides an updated estimate of the global prevalence of trachoma based on the most recent information available. Methods: A literature search of recent published and unpublished surveys in the 34 endemic prov- inces was carried out: the result of surveys that used the WHO trachoma grading system and additional information from regional and country experts served as basis to determine the prevalence of tra- choma in each provinces in Afghanistan.
Results: Population based surveys provided recent information for 24 out of 34 endemic provinces.
90.200 people are estimated to be suffering from active trachoma and 70.500 are estimated to have trichiasis.
Conclusions: The current estimate of prevalence of trachoma is lower than the previous WHO estimates: this can be explained by the success in implement- ing control strategy, by more accurate data, as well as by socio-economic development in endemic provinces.
