Summary

The purpose of this study undertaken 2014-2016 was to determine the prevalence of trachoma after interventions in 15 local government areas (LGAs) of Kebbi, Sokoto and Zamfara States, Nigeria. These LGAs had not necessarily completed the WHO-recommended numbers of MDA rounds indicated by their baseline, but given the chequered history of intervention and the long time period elapsed since the previous round of surveys, refocusing the programme by undertaking fresh estimates was felt to be a good idea. A population-based impact survey was conducted in each LGA using Global Trachoma Mapping Project protocols. The study concluded that progress towards elimination of trachoma had been made in these 15 LGAs. Eight of the 15 LGAs have now attained the elimination target for “trachommatous inflammation-follicular” (TF) while 10 LGAs have attained the elimination target for trichiasis.
