<p><strong>METHODS: </strong>A population-based prevalence survey was conducted in each Kano LGA. We used a two-stage systematic and quasi-random sampling strategy to select 25 households from each of 25 clusters in each LGA. All consenting household residents aged 1 year and above were examined for trachomatous inflammation-follicular (TF), trachomatous inflammation-intense (TI) and trichiasis.</p>

<p><strong>RESULTS: </strong>State-wide crude prevalence of TF in persons aged 1-9 years was 3.4% (95% CI 3.3-3.5%), and of trichiasis in those aged ≥15 years was 2.3% (95% CI 2.1-2.4%). LGA-level age- and sex-adjusted trichiasis prevalence in those aged ≥15 years ranged from 0.1% to 2.9%. All but 4 (9%) of 44 LGAs had trichiasis prevalences in adults above the elimination threshold of 0.2%. State-wide prevalence of trichiasis in adult women was significantly higher than in adult men (2.6% vs 1.8%; OR = 1.5, 95% CI 1.3-1.7; p = 0.001). Four of 44 LGAs had TF prevalences in 1-9 year-olds between 10 and 15%, while another six LGAs had TF prevalences between 5 and 9.9%. In 37 LGAs, &gt;80% of households had access to water within 30 minutes round-trip, but household latrine access was &gt;80% in only 19 LGAs.</p>

<p><strong>CONCLUSION: </strong>Trichiasis is a public health problem in most LGAs in Kano. Surgeons need to be trained and deployed to provide community-based trichiasis surgery, with emphasis on delivery of such services to women. Antibiotics, facial cleanliness and environmental improvement are needed in 10 LGAs.</p>
