To complete the baseline trachoma map worldwide by conducting population-based surveys in an estimated 1238 suspected endemic districts of 34 countries.A series national and sub-national projects owned, managed staffed ministries health, conduct house-to-house cluster random sample evaluation units, which generally correspond to "health district" size: populations 100,000-250,000 people. In each unit, we invite all residents aged 1 year older from h households c clusters be examined for...
Background Lymphatic filariasis (LF) is targeted for global elimination through treatment of entire at-risk populations with repeated annual mass drug administration (MDA). Essential program success defining and confirming the appropriate endpoint MDA when transmission presumed to have reached a level low enough that it cannot be sustained even in absence intervention. Guidelines advanced by WHO call assessment survey (TAS) determine if can stopped within an LF evaluation unit (EU) after at...
The rapid expansion of mobile networks globally, coupled with the decreasing cost equipment [1], is allowing global health programs increasingly to utilize mobile- and cloud-based technology in their efforts target important challenges public health. Our initial electronic data collection system employed personal digital assistants (PDAs) [2], [3], but these proved have significant scalability limitations. present report describes a second-generation, more efficient, cloud-based,...
In collaboration with the health ministries that we serve and other partners, set out to complete multiple-country Global Trachoma Mapping Project. To maximize accuracy reliability of its outputs, needed in-built, practical mechanisms for quality assurance control. This article describes how those were created deployed.

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, to identify factors associated with disease.Methods: Using standardized methodologies training developed for Global Trachoma Mapping Project, we conducted cross-sectional community-based surveys from December 2012...
Background There remains a lack of epidemiological data on the geographical distribution trachoma to support global mapping and scale up interventions for elimination trachoma. The Global Atlas Trachoma (GAT) was launched in 2011 address these needs provide standardised, updated accessible maps. This paper uses included GAT describe burden Africa. Methods Data assembly used structured searches published unpublished literature identify cross-sectional since 1980. Survey were abstracted into...
Background Trichiasis is present when one or more eyelashes touches the eye. Uncorrected, it can cause blindness. Accurate estimates of numbers affected, and their geographical distribution, help guide resource allocation. Methods We obtained district-level trichiasis prevalence in adults for 44 endemic previously-endemic countries. used (1) most recent data a district, if than estimate was available; (2) age- sex-standardized corrections historic estimates, where raw were (3) adjusted using...
Purpose Population-based prevalence surveys are essential for decision-making on interventions to achieve trachoma elimination as a public health problem. This paper outlines the methodologies of Tropical Data, which supports work undertake those surveys.
Purpose: We sought to determine the prevalence of trachoma in 44 Local Government Areas (LGAs) Kano State, Nigeria.Methods: A population-based survey was conducted each LGA. used a two-stage systematic and quasi-random sampling strategy select 25 households from clusters All consenting household residents aged 1 year above were examined for trachomatous inflammation–follicular (TF), inflammation–intense (TI) trichiasis.Results: State-wide crude TF persons 1–9 years 3.4% (95% CI 3.3–3.5%),...
Background Blinding trachoma is targeted for elimination by 2020 using the SAFE strategy (Surgery, Antibiotics, Facial cleanliness, and Environmental improvements). Annual mass drug administration (MDA) with azithromycin a cornerstone of this strategy. If baseline prevalence clinical signs trachomatous inflammation – follicular among 1-9 year-olds (TF1-9) ≥10% but <30%, World Health Organization guidelines are at least 3 annual MDAs; if ≥30%, 5. We assessed likelihood achieving global target...
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) children aged 1–9 years and trichiasis adults 15 above. We conducted surveys complete map Mozambique.Methods: Between July 2012 May 2015, we carried out cross-sectional 96 evaluation units (EUs) covering 137 districts.Results: A total 269,217 individuals were enumerated 249,318 people examined using simplified...
Trachoma is a major cause of blindness in Ethiopia, and targeted for elimination as public health problem by the year 2020. Prevalence data are needed to plan interventions. We set out estimate prevalence trachoma each evaluation unit grouped districts ("woredas") Benishangul Gumuz region, Ethiopia.We conducted seven cross-sectional community-based surveys, covering 20 woredas, between December 2013 January 2014, part Global Mapping Project (GTMP). The standardized GTMP training package...
Purpose: To determine the prevalence of trachoma in each 25 local government areas (LGAs) Niger State, Nigeria.Methods: A population-based cross-sectional survey was conducted State LGA between March and April 2014, as part Global Trachoma Mapping Project (GTMP). GTMP protocols were used planning conduct surveys. Using probability proportional to size, clusters selected; these clusters, households enrolled for survey. All residents aged 1 year older examined by GTMP-certified graders...
Purpose: To determine the local government area (LGA)-level prevalence of trachoma in all 34 LGAs Katsina State.Methods: A population-based survey was conducted each LGA State, using Global Trachoma Mapping Project methodology. We used a 3-stage cluster random sampling strategy to select 25 households from clusters. examined residents selected aged 1 year and older for clinical signs trachomatous inflammation–follicular (TF), inflammation–intense trichiasis, World Health Organization (WHO)...
Purpose: In Ethiopia, trachoma is a major public health problem, accounting for 11.5% of all cases blindness. Gambella, one the country's most remote regions, 2005–2006 National Survey Blindness, Low Vision and Trachoma estimated region-level prevalence active 19.1% in those aged 1–9 years. Detailed district or sub-regional level estimates are required to implement interventions.Methods: Population-based surveys were carried out following 2-stage cluster random sampling methodology Global...

In cluster, households all consenting residents aged 1 year older were examined trachomatous inflammation–follicular (TF) trichiasis, using...
To prepare for global elimination of trachoma by 2020, the World Health Organization (WHO) recommends mapping at district-level to enable planning activities in affected populations. The aim our study was provide data on each local government area (LGA) Kaduna State, Nigeria, as such were previously unavailable.As part Global Trachoma Mapping Project (GTMP), a population-based cross-sectional survey conducted 23 LGAs between May and June 2013. protocols GTMP used.The prevalence trachomatous...
Neglected tropical diseases (NTDs) affect more than 1,000,000,000 poor and marginalized people worldwide [1]. NTDs are caused by diverse pathogens with differing modes of transmission a range vectors intermediate hosts, which have their own ecological peculiarities. While there is considerable overlap in the geographical distribution different at national level [1], epidemiological differences individual give rise to marked variation local levels. Since cost-effectiveness intervention...
Whilst previous work has identified clustering of the active trachoma sign "trachomatous inflammation—follicular" (TF), there is limited understanding spatial structure trachomatous trichiasis (TT), rarer, end-stage, blinding form disease. Here we use community-level TF prevalence, information on access to water and sanitation, large-scale environmental socio-economic indicators model variation in TT prevalence Benin, Cote d'Ivoire, DRC, Guinea, Ethiopia, Malawi, Mozambique, Nigeria, Sudan...
Purpose: Following a first phase of trachoma mapping in Malawi with the Global Trachoma Mapping Project, we identified and mapped districts previously suspected to be non-endemic, although adjacent estimated prevalences indicating public health problem.Methods: We conducted population-based surveys eight evaluation units (EUs) comprising (total population 3,230,272). A 2-stage cluster random sampling design allowed us select 30 households from each clusters per EU; all residents aged 1 year...
