Trachoma in the regions of Adrar and Tagant in Mauritania.

Abstract

Introduction: Trachoma is a keratoconjunctivitis caused by a bacterium chlamydia trachomatis transmitted by dirty hands, soiled linen and lies. Trachoma is a real public health problem in developing countries. objective : To determine the prevalence of follicular trachoma and trachomatous trichiasis in the Adrar and Tagant regions. Materials and Methods : This is a retrospective longitudinal study aimed analytically over a period from 2004‑ 2017 based on series of surveys conducted by NPCB and its partners. Results : Our study shows a follicular trachoma rate of 27.12 % in 2004; 11.2 % in 2007; 7.3 % in 2011 and 2.99 % in 2017, as well as a trachomatous trichiasis rate 2.2 % in 2004; 1 % in 2007; 0,48 % in 2011 and 0,12 % in 2017 this in the Adrar region. In the region of Tagant our study a prevalence of follicular trachoma 24.35 % in 2004; 6,8 % in 2007; 0,6 % in 2011 and 4,13 % in 2017 and a low rate of trichiasis in this region as 0.85 % in 2004; 0,7 % in 2007; 0,06 % in 2011 and 0 % in 2017. Conclusion : Trachoma, which was a real public health problem in the Adrar and Tagant regions in the early 2000s, has been signi icantly reduced, allowing the transition from the endemic state to the pre‑certi ication phase that requires Epidemiological monitoring., but which decreased signi icantly thanks to the implementation of the SAFE strategy
