PurposeThe World Health Organization's (WHO's) global trachoma elimination programme recommends mapping of trachoma at district level for planning of elimination activities in affected populations. This study aimed to provide data on trachoma prevalence for the Area Councils of Nigeria's Federal Capital Territory (FCT).MethodsUsing the Global Trachoma Mapping Project (GTMP) protocols, in March and April 2014, we conducted a population-based cross-sectional survey in each of the six Area Councils of FCT. Signs were defined based on the WHO simplified grading scheme.Results98% to 100% of the targeted households were enrolled in each Area Council. The number of children aged 1-9 years examined per Area Council ranged from 867 to 1248. The number of persons aged ≥15 years examined ranged from 1302 to 1836. The age-adjusted prevalence of trachomatous inflammation-follicular in 1-9-year-olds was

PurposeThe purpose of these surveys was to determine the prevalence of trachomatous inflammation-follicular (TF) in children aged 1-9 years and trichiasis prevalence in persons aged ≥15 years, in 13 Local Government Areas (LGAs) of Taraba State, Nigeria.MethodsThe surveys followed Global Trachoma Mapping Project (GTMP) protocols. Twenty-five households were selected from each of 25 clusters in each LGA, using two-stage cluster sampling providing probability of selection proportional to cluster size. Survey teams examined all the residents of selected households aged ≥1 year for the clinical signs TF, trachomatous inflammation-intense (TI) and trichiasis.ResultsThe prevalence of TF in children aged 1-9 years in the 13 LGAs ranged from 0.0-5.0%; Ussa LGA had the highest prevalence of 5% (95%CI: 3.4-7.2). Trichiasis prevalence ranged from 0.0-0.8%; seven LGAs had trichiasis prevalences above the threshold for elimination. The backlog of trichiasis in the 13 LGAs (estimated combined population 1,959,375) was 3,185 people. There is need to perform surgery for at least 1,835 people to attain a trichiasis prevalence in each LGA of 80% of households with access to improved latrines.ConclusionOne of 13 LGAs requires antibiotic mass drug administration for active trachoma. Community-based trichiasis surgery needs to be provided in seven LGAs. There is a need to increase household-level access to improved washing water and latrines across the State.

PurposeTrachoma is to be eliminated as a public health problem by 2020. To help the process of planning interventions where needed, and to provide a baseline for later comparison, we set out to complete the map of trachoma in Afar, Ethiopia, by estimating trachoma prevalence in evaluation units (EUs) of grouped districts ("woredas").MethodsWe conducted seven community-based surveys from August to October 2013, using standardised Global Trachoma Mapping Project (GTMP) survey methodologies.ResultsWe enumerated 5065 households and 18,177 individuals in seven EUs covering 19 of Afar's 29 woredas; the other ten were not accessible. 16,905 individuals (93.0%) were examined, of whom 9410 (55.7%) were female. One EU incorporating four woredas (Telalak, Dalefage, Dewe, Hadele Ele) was shown to require full implementation of the SAFE strategy for three years before impact survey, with a trachomatous inflammation-follicular (TF) prevalence in 1-9-year-olds of 17.1% (95%CI 9.4-25.5), and a trichiasis prevalence in adults aged ≥15 years of 1.2% (95%CI 0.6-2.0). Five EUs, covering 13 woredas (Berahle, Aba'ala, Dupti, Kurri, Elidihare, Ayesayeta, Afamboo, Bure Mudaitu, Gewane, Amibara, Dulecho, Dalolo, and Konebo), had TF prevalences in children of 5-9.9% and need one round of azithromycin mass treatment and implementation of the F and E components of SAFE before re-survey; three of these EUs had trichiasis prevalences in adults ≥0.2%. The final EU (Mile, Ada'ar) had a sub-threshold TF prevalence and a trichiasis prevalence in adults just >0.2%.ConclusionTrachoma is a public health problem in Afar, and implementation of the SAFE strategy is required.

PurposeEthiopia is highly trachoma endemic. Baseline mapping was needed in Ethiopia's Somali Region to guide elimination efforts.MethodsCross-sectional community-based surveys were conducted in 34 suspected trachoma-endemic woredas, grouped as 14 evaluation units (EUs), using a standardised mapping methodology developed for the Global Trachoma Mapping Project.ResultsIn total, 53,467 individuals were enumerated. A total of 48,058 (89.9%) were present at the time of survey teams' visits and consented to examination. The prevalence of trachomatous inflammation-follicular (TF) among children aged 1-9 years ranged from 4.1% in the EU covering Danot, Boh, and Geladin woredas in Doolo Subzone to 38.1% in the EU covering Kebribeyah and Hareshen woredas in Fafan Subzone (East). The trichiasis prevalence among adults aged over 15 years varied from 0.1% in the EU covering Afder, Bare, and Dolobay woredas in Afder Subzone (West) to 1.2% in the EU covering Awbere in Fafan Subzone (West).ConclusionMass drug administration (MDA) with azithromycin is needed in 13 EUs (population 2,845,818). Two EUs (population 667,599) had TF prevalences in 1-9-year-olds of ≥30% and will require at least 5 years of MDA; 5 EUs (population 1,1193,032) had TF prevalences of 10-29.9% and need at least three years of MDA; 6 EUs (population 985,187) had TF prevalences of 5-9.9% and need at least one round of azithromycin distribution before re-survey. In all 13 of these EUs, implementation of facial cleanliness and environmental improvement measures is also needed. Surveys are still needed in the remaining 34 unmapped woredas of Somali Region.

GOVERNMENT policy ,GOVERNMENT programs - Abstract
Monitoring, evaluation, and research activities generate important data, but they often fail to change policies or programs. In addition, local program staff and partners often feel disconnected from these activities, which undermines their ownership of data and results. To bridge the gaps between monitoring, evaluation, and research and to give them a common purpose through locally owned, actionable learning, we developed an integrated Monitoring, Evaluation, Research, Learning, and Adapting (MERLA) framework. Implemented and refined in over 20 countries, the framework integrates data-gathering methodologies with collaborative techniques for translating evidence into knowledge that influences program practice and government policy. In this publication, we describe the MERLA framework and present two case studies demonstrating how its application enables learning and adaptation led by in-country teams. [ABSTRACT FROM AUTHOR]

SAMPLE size (Statistics) , *TRACHOMA , *CLUSTER sampling - Abstract
As trachoma programs move towards eliminating trachoma as a public health problem, the number of surveys necessary to evaluate the status of trachomatous trichiasis (TT) increases. Currently, the World Health Organization endorses a district-level population-based prevalence survey for trachoma that involves a two-stage cluster design. We explored the validity of implementing this survey design in larger geographic areas to gain cost efficiencies. We evaluated the change in precision due to combining geographically contiguous and homogenous districts into single evaluation units (EUs) and modulating the sample size by running simulations on existing datasets. Preliminary findings from two opportunities in Tanzania show variability in the appropriateness in conducting this survey across larger geographies. These preliminary findings stress the importance of determining what is meant by homogeneity in terms of TT before combining multiple districts into a single EU. [ABSTRACT FROM AUTHOR]

Purpose We sought to determine the prevalence of trachoma in 44 Local Government Areas (LGAs) of Kano State, Nigeria. Methods 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. Results 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, >80% of households had access to water within 30 minutes round-trip, but household latrine access was >80% in only 19 LGAs. Conclusion 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.

Purpose: Surveys are needed to guide trachoma control efforts in Mozambique, with WHO guidelines for intervention based on the prevalence of trachomatous inflammation-follicular (TF) in children aged 1-9 years and the prevalence of trichiasis in adults aged 15 years and above. We conducted surveys to complete the map of trachoma prevalence in Mozambique. Methods: Between July 2012 and May 2015, we carried out cross-sectional surveys in 96 evaluation units (EUs) covering 137 districts. Results: A total of 269,217 individuals were enumerated and 249,318 people were examined using the WHO simplified trachoma grading system. Overall, 102,641 children aged 1-9 years, and 122,689 individuals aged 15 years and above were examined. The prevalence of TF in children aged 1-9 years was ≥10% in 12 EUs, composed of 20 districts, covering an estimated total population of 2,455,852. These districts require mass distribution of azithromycin for at least 3 years before re-survey. The TF prevalence in children was 5.0-9.9% in 17 EUs (28 districts, total population 3,753,039). 22 EUs (34 districts) had trichiasis prevalences ≥0.2% in adults 15 years and above, and will require public health action to provide surgical services addressing the backlog of trichiasis. Younger age, more children resident in the household, and living in a household that had an unimproved latrine or no latrine facility, were independently associated with an increased odds of TF in children aged 1-9 years. Conclusions: Trachoma represents a significant public health problem in many areas of Mozambique. [ABSTRACT FROM AUTHOR]

Purpose: Ethiopia is highly trachoma endemic. Baseline mapping was needed in Ethiopia's Somali Region to guide elimination efforts. Methods: Cross-sectional community-based surveys were conducted in 34 suspected trachoma-endemic woredas, grouped as 14 evaluation units (EUs), using a standardised mapping methodology developed for the Global Trachoma Mapping Project. Results: In total, 53,467 individuals were enumerated. A total of 48,058 (89.9%) were present at the time of survey teams' visits and consented to examination. The prevalence of trachomatous inflammation-follicular (TF) among children aged 1-9 years ranged from 4.1% in the EU covering Danot, Boh, and Geladin woredas in Doolo Subzone to 38.1% in the EU covering Kebribeyah and Hareshen woredas in Fafan Subzone (East). The trichiasis prevalence among adults aged over 15

TRACHOMA ,WATER quality ,SANITATION ,DEMOGRAPHIC surveys - Abstract
Background: The World Health Organization's (WHO's) global trachoma elimination programme recommends mapping of trachoma at district level for planning of elimination activities in affected populations. This study aimed to provide data on trachoma prevalence for the Area Councils of Nigeria's Federal Capital Territory (FCT). Methodology: Using the Global Trachoma Mapping Project (GTMP) protocols, in March and April 2014, we conducted a population-based cross-sectional survey in each of the six Area Councils of FCT. Signs were defined based on the WHO simplified grading scheme. Results: 98% to 100% of the targeted households were enrolled in each Area Council. The number of children aged 1-9 years examined per Area Council ranged from 867 to 1248. The number of persons aged ≥15 years examined ranged from 1302 to 1836. The age-adjusted prevalence of trachomatous inflammation—follicular in 1-9-year-olds was <5% in each Area Council. The age- and gender-adjusted prevalence of trichiasis in those aged ≥15 years ranged from 0.0% to 0.3%; two Area Councils (Gwagwalada and Kwali) had prevalences above the 0.2% elimination threshold. The proportion of households with access to improved latrines and water sources ranged from 17 to 90% and 39 to 85% respectively. Conclusions: Gwagwalada and Kwali Area Councils need to perform more trichiasis surgeries to attain the trichiasis elimination prevalence target of 0.2% in persons aged ≥15 years. No Area Council requires mass antibiotic administration for the purposes of trachoma's elimination as a public health problem. All Area Councils need to accelerate provision of access to improved water sources and latrine facilities, to achieve universal coverage. [ABSTRACT FROM AUTHOR]

TRACHOMA ,LOCAL government ,PUBLIC health ,INFLAMMATION - Abstract
Background: The purpose of these surveys was to determine the prevalence of trachomatous inflammation—follicular (TF) in children aged 1-9 years and trichiasis prevalence in persons aged ≥15 years, in 13 Local Government Areas (LGAs) of Taraba State, Nigeria. Method: The surveys followed Global Trachoma Mapping Project (GTMP) protocols. Twenty-five households were selected from each of 25 clusters in each LGA, using two-stage cluster sampling providing probability of selection proportional to cluster size. Survey teams examined all the residents of selected households aged ≥1 year for the clinical signs TF, trachomatous inflammation—intense (TI) and trichiasis. Results: The prevalence of TF in children aged 1-9 years in the 13 LGAs ranged from 0.0-5.0%; Ussa LGA had the highest prevalence of 5% (95%CI: 3.4-7.2). Trichiasis prevalence ranged from 0.0-0.8%; seven LGAs had trichiasis prevalences above the threshold for elimination. The backlog of trichiasis in the 13 LGAs (estimated combined population 1,959,375) was 3,185 people. There is need to perform surgery for at least 1,835 people to attain a trichiasis prevalence in each LGA of <0.2% in persons aged ≥15 years. In six of the 13 LGAs, 80% of households could access washing water within 1 km of the household, but only one LGA had >80% of households with access to improved latrines. Conclusion: One of 13 LGAs requires antibiotic mass drug administration for active trachoma. Community-based trichiasis surgery needs to be provided in seven LGAs. There is a need to increase household-level access to improved washing water and latrines across the State. [ABSTRACT FROM AUTHOR]

TRACHOMA ,INFLAMMATION ,DEMOGRAPHIC surveys ,BLINDNESS - Abstract
Purpose: Trachoma is to be eliminated as a public health problem by 2020. To help the process of planning interventions where needed, and to provide a baseline for later comparison, we set out to complete the map of trachoma in Afar, Ethiopia, by estimating trachoma prevalence in evaluation units (EUs) of grouped districts ("woredas"). Methods: We conducted seven community-based surveys from August to October 2013, using standardised Global Trachoma Mapping Project (GTMP) survey methodologies. Results: We enumerated 5065 households and 18,177 individuals in seven EUs covering 19 of Afar's 29 woredas; the other ten were not accessible. 16,905 individuals (93.0%) were examined, of whom 9410 (55.7%) were female. One EU incorporating four woredas (Telalak, Dalefage, Dewe, Hadele Ele) was shown to require full implementation of the SAFE strategy for three years before impact survey, with a trachomatous inflammation-follicular (TF) prevalence in 1-9-year-olds of 17.1% (95%CI 9.4-25.5), and a trichiasis prevalence in adults aged ≥15 years of 1.2% (95%CI 0.6-2.0). Five EUs, covering 13 woredas (Berahle, Aba'ala, Dupti, Kurri, Elidihare, Ayesayeta, Afamboo, Bure Mudaitu, Gewane, Amibara, Dulecho, Dalolo, and Konebo), had TF prevalences in children of 5-9.9% and need one round of azithromycin mass treatment and implementation of the F and E components of SAFE before re-survey; three of these EUs had trichiasis prevalences in adults ≥0.2%. The final EU (Mile, Ada'ar) had a sub-threshold TF prevalence and a trichiasis prevalence in adults just >0.2%. Conclusion: Trachoma is a public health problem in Afar, and implementation of the SAFE strategy is required. [ABSTRACT FROM AUTHOR]

Purpose: To complete the baseline trachoma map in Oromia, Ethiopia, by determining prevalences of trichiasis and trachomatous inflammation – follicular (TF) at evaluation unit (EU) level, covering all districts (woredas) without current prevalence data or active control programs, and to identify factors associated with disease. Methods: Using standardized methodologies and training developed for the Global Trachoma Mapping Project, we conducted cross-sectional community-based surveys from December 2012 to July 2014. Results: Teams visited 46,244 households in 2037 clusters from 252 woredas (79 EUs). A total of 127,357 individuals were examined. The overall age- and sex-adjusted prevalence of trichiasis in adults was 0.82% (95% confidence interval, CI, 0.70–0.94%), with 72 EUs covering 240 woredas having trichiasis prevalences above the elimination threshold of 0.2% in those aged ≥15 years. The overall age-adjusted TF prevalence in 1–9-year-olds was 23.4%, with 56 EUs covering 218 woredas shown to need implementation of the A, F and E components of the SAFE strategy (surgery, antibiotics, facial cleanliness and environmental improvement) for 3 years before impact surveys. Younger age, female sex, increased time to the main source of water for face-washing, household use of open defecation, low mean precipitation, low mean annual temperature, and lower altitude, were independently associated with TF in children. The 232 woredas in 64 EUs in which TF prevalence was ≥5% require implementation of the F and E components of the SAFE strategy. Conclusion: Both active trachoma and trichiasis are highly prevalent in much of Oromia, constituting a significant public health problem for the region. [ABSTRACT FROM PUBLISHER]

- Abstract
Purpose: We sought to determine the prevalence of trachoma in 44 Local Government Areas (LGAs) of Kano State, Nigeria., Methods: 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., Results: 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, >80% of households had access to water within 30 minutes round-trip, but household latrine access was >80% in only 19 LGAs., Conclusion: 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.
