Although a wealth of information on its occurrence and prevalence is available in the literature, synthesized and harmonized data at the regional and continental scales are lacking. To fill this gap the Food and Agriculture Organization of the United Nations (FAO) launched the Atlas of tsetse and AAT, jointly implemented with the International Atomic Energy Agency (IAEA) in the framework of the Programme Against African Trypanosomosis (PAAT).</p></sec><sec><title>Methods</title><p>The Atlas aims to build and regularly update a geospatial database of tsetse species occurrence and AAT at the continental level. The present paper focuses on the methodology to assemble a dynamic database of AAT, which hinges on herd-level prevalence data as estimated using various diagnostic techniques. A range of ancillary information items is also included (e.g. trypanosome species, survey period, species and breed of animals, husbandry system, etc.). Input data were initially identified through a literature review.</p></sec><sec><title>Results</title><p>Preliminary results are presented for Ethiopia, Kenya and Uganda in East Africa: 122 papers were identified and analyzed, which contained field data collected from January 1990 to December 2013. Information on AAT was extracted and recorded for 348 distinct geographic locations. The presented distribution maps exemplify the range of outputs that can be directly generated from the AAT database.</p></sec><sec><title>Conclusions</title><p>Activities are ongoing to map the distribution of AAT in all affected countries and to develop the tsetse component of the Atlas. The presented methodology is also being transferred to partners in affected countries, with a view to developing capacity and strengthening data management, harmonization and sharing. In the future, geospatial modelling will enable predictions to be made within and beyond the range of AAT field observations. This variety of information layers will inform decisions on the most appropriate, site-specific strategies for intervention against AAT. Data on the occurrence of human-infective trypanosomes in non-human hosts will also provide valuable information for sleeping sickness control and elimination.</p></sec></div></front><back><div1

Although a wealth of information on its occurrence and prevalence is available in the literature, synthesized and harmonized data at the regional and continental scales are lacking. To fill this gap the Food and Agriculture Organization of the United Nations (FAO) launched the Atlas of tsetse and AAT, jointly implemented with the International Atomic Energy Agency (IAEA) in the framework of the Programme Against African Trypanosomosis (PAAT).</p></sec><sec><title>Methods</title><p>The Atlas aims to build and regularly update a geospatial database of tsetse species occurrence and AAT at the continental level. The present paper focuses on the methodology to assemble a dynamic database of AAT, which hinges on herd-level prevalence data as estimated using various diagnostic techniques. A range of ancillary information items is also included (e.g. trypanosome species, survey period, species and breed of animals, husbandry system, etc.). Input data were initially identified through a literature review.</p></sec><sec><title>Results</title><p>Preliminary results are presented for Ethiopia, Kenya and Uganda in East Africa: 122 papers were identified and analyzed, which contained field data collected from January 1990 to December 2013. Information on AAT was extracted and recorded for 348 distinct geographic locations. The presented distribution maps exemplify the range of outputs that can be directly generated from the AAT database.</p></sec><sec><title>Conclusions</title><p>Activities are ongoing to map the distribution of AAT in all affected countries and to develop the tsetse component of the Atlas. The presented methodology is also being transferred to partners in affected countries, with a view to developing capacity and strengthening data management, harmonization and sharing. In the future, geospatial modelling will enable predictions to be made within and beyond the range of AAT field observations. This variety of information layers will inform decisions on the most appropriate, site-specific strategies for intervention against AAT. Data on the occurrence of human-infective trypanosomes in non-human hosts will also provide valuable information for sleeping sickness control and elimination.</p></sec></abstract><trans-abstract xml:lang="fr"><sec><title>Résumé</title><sec><title>Introduction</title><p>La trypanosomose animale africaine (TAA), aussi appelée nagana, est largement répandue dans les zones d’Afrique sub-saharienne infestées par les glossines.

The aetiological agents (several species of unicellular flagellates called trypanosomes) are transmitted by the infected bite of the tsetse fly (Genus: <italic>Glossina</italic>). The disease causes heavy direct losses to livestock keepers as measured by mortality, morbidity and reduced productivity at the herd level. In the deprived rural settings where it occurs, AAT further reduces food security by limiting the exploitation of animal draught power and by constraining the optimal utilization of fertile lands [<xref ref-type="bibr" rid="B2">2</xref>]. Nagana is widely distributed across the tsetse-infested belt of sub-Saharan Africa, where approximately 60 million cattle are estimated to be at risk of infection over an area of about 10 million km<sup>2</sup>[<xref ref-type="bibr" rid="B3">3</xref>]. Sleeping sickness, or human African trypanosomosis (HAT), is the human form of the disease, which occurs in more circumscribed foci of endemicity [<xref ref-type="bibr" rid="B4">4</xref>,<xref ref-type="bibr" rid="B5">5</xref>] and 70 million people are estimated to be at risk of contracting the disease [<xref ref-type="bibr" rid="B5">5</xref>,<xref ref-type="bibr" rid="B6">6</xref>].</p><p>After a long period of neglect, during the last 15 years ambitious initiatives have been trying to address the problem of tsetse-transmitted trypanosomosis in its continental dimension.</p><p>In 1997, the Programme against African Trypanosomosis (PAAT) was established to assist affected African countries in their efforts to control and eventually eliminate the disease [<xref ref-type="bibr" rid="B7">7</xref>]. PAAT brought together the efforts of the Food and Agriculture Organization of the United Nations (FAO), the World Health Organization (WHO), the International Atomic Energy Agency (IAEA) and the African Union Interafrican Bureau for Animal Resources (AU-IBAR). At the same time, resolutions of the World Health Assembly prompted WHO to strengthen its support to countries affected by sleeping sickness [<xref ref-type="bibr" rid="B8">8</xref>,<xref ref-type="bibr" rid="B9">9</xref>], with the objective to eliminate HAT as a public health problem and to establish sustained surveillance systems in all endemic countries. Finally, successive decisions of the Heads of State and Government of the African Union in 2000 (AHG/156 – XXXVI) and 2001 (AHG/169 – XXXVII) endorsed and committed to the plan of action for the Pan-African Tsetse and Trypanosomosis Eradication Campaign (PATTEC) [<xref ref-type="bibr" rid="B10">10</xref>].</p><p>If sound decisions are to be made, these important initiatives need reliable epidemiological information at a range of spatial scales. For example, spatially-explicit evidence is necessary to select priority areas for intervention [<xref ref-type="bibr" rid="B11">11</xref>], both where disease control can be regarded as a cost-effective option [<xref ref-type="bibr" rid="B12">12</xref>,<xref ref-type="bibr" rid="B13">13</xref>], and where the elimination of the tsetse fly vector appears as a feasible and sustainable endeavour [<xref ref-type="bibr" rid="B14">14</xref>].</p><p>In order to meet this need for harmonized and comprehensive spatial information, a recent WHO/FAO initiative in the framework of PAAT (i.e. the Atlas of HAT), has focused on the systematic mapping of HAT occurrence [<xref ref-type="bibr" rid="B4">4</xref>,<xref ref-type="bibr" rid="B15">15</xref>,<xref ref-type="bibr" rid="B16">16</xref>] and risk [<xref ref-type="bibr" rid="B6">6</xref>,<xref ref-type="bibr" rid="B17">17</xref>]. In a related activity, a comprehensive and spatially-explicit dataset has also been assembled for sleeping sickness cases reported from non-endemic countries [<xref ref-type="bibr" rid="B18">18</xref>].</p><p>Despite a compelling need, the substantial progress made in mapping HAT has not yet been matched by comparable advances in the continental mapping of tsetse and AAT [<xref ref-type="bibr" rid="B3">3</xref>]. Tsetse distribution maps at the African level are old [<xref ref-type="bibr" rid="B19">19</xref>,<xref ref-type="bibr" rid="B20">20</xref>] and continental maps of AAT have never been generated [<xref ref-type="bibr" rid="B3">3</xref>]. This knowledge gap poses serious constraints to evidence-based decision-making, and severely limits the possibility to assess the progress towards the goals set by various stakeholders at the continental level.</p><p>In an effort to fill this gap, FAO launched the Atlas of tsetse and AAT, an initiative to which IAEA has adhered to in the framework of PAAT [<xref ref-type="bibr" rid="B21">21</xref>,<xref ref-type="bibr" rid="B22">22</xref>]. Its immediate goal is to assemble contemporary, georeferenced data on the occurrence of <italic>Glossina</italic> species and AAT in sub-Saharan Africa. The present paper focuses on the AAT component and describes the methodology developed to assemble a database of AAT distribution. Preliminary results are presented for three east African countries, i.e. Ethiopia, Kenya and Uganda, and the way forward is outlined.</p></sec><sec sec-type="methods"><title>Methods</title><p>The general approach adopted to build the Atlas of tsetse and AAT is summarized in Figure <xref ref-type="fig" rid="F1">1</xref>. In essence, all publications and input data derived from the various sources are collated and stored in a centralized data repository. Subsequently, selected information items are extracted from the sources, harmonized and entered into a geo-spatial database. The database is structured into three simple tables, which are devoted to data sources, geographical data and epidemiological information respectively. The data abstraction protocol is described in detail in the Additional file <xref ref-type="supplementary-material" rid="S1">1</xref>, and it is an adaptation of similar work carried out for malaria [<xref ref-type="bibr" rid="B23">23</xref>]. Geographic Information Systems (GIS) enable distribution maps to be generated directly from the geo-database, while geospatial modelling will be used in the future to make predictions on tsetse and AAT distribution within and beyond the range of field observations.</p><fig id="F1" position="float"><label>Figure 1</label><caption><p>Sources, structure and outputs of the Atlas of tsetse and African animal trypanosomosis (AAT).</p></caption><graphic xlink:href="1756-3305-7-39-1"></graphic></fig><p>At the present first stage of development, the Atlas is focusing on information published in peer-reviewed articles from scientific journals. Grey literature and additional unpublished datasets will be addressed at a later stage.</p><sec><title>Data sources</title><p>The search strategy used to identify suitable scientific publications makes use of internet libraries, archives and indexes. In particular, the PAAT Tsetse and Trypanosomosis Information Bulletin (<ext-link ext-link-type="uri" xlink:href="http://www.fao.org/ag/againfo/programmes/en/paat/ttiq.html">http://www.fao.org/ag/againfo/programmes/en/paat/ttiq.html</ext-link>), PubMed Central (<ext-link ext-link-type="uri" xlink:href="http://www.ncbi.nlm.nih.gov/pubmed/">http://www.ncbi.nlm.nih.gov/pubmed/</ext-link>) and CabDirect (<ext-link ext-link-type="uri" xlink:href="http://www.cabdirect.org/">http://www.cabdirect.org/</ext-link>) are the main tools used for data search. A temporal criterion of inclusion was applied, in that papers were only taken into consideration if containing field data collected from January 1990 onwards.</p><p>For each identified data source, a file is stored in the data repository, and a record is created in the ‘Data sources’ table of the AAT geo-database. The record includes a unique numerical identifier for the data source, the names of the authors, as well as the title and the year of publication. The study country is also noted, alongside external and internal links – the former corresponding to a URL (i.e. internet address of the paper), and the latter to an internal link to the respective PDF file in the data repository. The ‘Data sources’ table is completed with information on the type of spatially-explicit data the paper contains (i.e. data on animal trypanosomosis, on tsetse occurrence, or both). This latter flag enables papers to be rapidly selected for data extraction for the AAT and the tsetse components of the Atlas.</p></sec><sec><title>Geographical data</title><p>The table for geographical data is designed to capture information on the locations of epidemiological relevance, as described and referred to in the data sources. In particular, the table for geographic data includes: a unique numeric identifier of the location, the location name, the geographic coordinates (i.e. latitude and longitude, based on the WGS84 datum), the country name and the names of lower-level administrative units (provinces, districts, etc.). Each location is identified by a single set of coordinates, and therefore it is represented as a point entity in the GIS. If not available in the papers, geographic coordinates are searched from a variety of sources, including many publicly available gazetteers [<xref ref-type="bibr" rid="B15">15</xref>].</p><p>Although represented as point entities, the epidemiological data referring to the different locations will always have a bidimensional area of applicability. For example, if all animals sampled in a survey come from a single village and they are managed sedentarily, the survey point will probably refer to an area of a few square kilometres. By contrast, if a source reports the AAT prevalence for a whole district, it is the centroid of the district that will identify the survey in the database and in the GIS, and that point will be representative of a broader area. If available, the exact surface area of the survey is recorded in the database (in km<sup>2</sup>). However, in most cases the data source (i.e. the paper) only enables the size of the study area to be estimated with a degree of approximation. Therefore, six broad categories were defined: ≤ 10 km<sup>2</sup>, > 10 and ≤ 25 km<sup>2</sup>, > 25 and ≤ 100 km<sup>2</sup>, > 100 and ≤ 500 km<sup>2</sup>, > 500 and ≤ 1,000 km<sup>2</sup>, and > 1,000 and ≤ 10,000 km<sup>2</sup>. Lastly, if the geographic information included in the paper is so vague, or so widely spread, that it does not even fall in the last category, the related epidemiological data are not considered and are excluded from the Atlas.</p></sec><sec><title>Epidemiological data</title><p>The table containing epidemiological data is the cornerstone of the AAT database. Each record is structured as follows: a unique identifier of the survey, the survey period, diagnostic method, sample size, animal species, animal breed, age range, sex and husbandry system. Note is taken on whether the sample can be considered random, and therefore representative of the population of the area as a whole. Also, information on recent or ongoing interventions against tsetse and on the use of trypanocidal drugs is recorded. In this context, recent interventions are those implemented in the few years preceding the survey. Trypanosomal infections can be captured in terms of presence/absence, estimated prevalence and number of infected animals. Each record also includes identifiers for the geographic location and for the source, which enable the epidemiological records to be linked to the complementary information in the tables ‘Data Sources’ and ‘Geographical data’.</p><p>More details are provided below on such relevant aspects as the species of hosts and parasites that are considered in the Atlas, and on diagnostic methods.</p><sec><title>Hosts and parasite species</title><p>The range of animal hosts selected for inclusion in the Atlas of AAT is wide, and comprises all domestic and wild vertebrates for which data can be identified. This includes cattle, sheep, goats, pigs, horses, donkeys, mules, camels, dogs, as well as a number of wild animals including reptiles. Vertebrate hosts for which trypanosomal infection may not have a direct economic impact were included to gain insights into the epidemiological significance of the different reservoirs.</p><p>Concerning the parasite species, the causative agents of nagana include several species of tsetse-transmitted trypanosomes. Four species of major veterinary importance are recognized, and they are therefore selected for inclusion in the Atlas of AAT: <italic>Trypanosoma vivax</italic> (sub-genus <italic>Duttonella</italic>), <italic>T. congolense</italic> and <italic>T. simiae</italic> (sub-genus <italic>Nannomonas</italic>) and <italic>T. brucei</italic> (sub-genus <italic>Trypanozoon</italic>). Although rarely reported, <italic>T. suis</italic> (sub-genus <italic>Pycnomonas</italic>), a swine-specific trypanosome [<xref ref-type="bibr" rid="B1">1</xref>], is also included in the database. Information on the occurrence of the different subgroups (or types) of <italic>T. congolense</italic> (namely savannah, forest/riverine and Kenya coast/kilifi) is also recorded when biochemical and molecular tools have enabled this level of characterization (the three subgroups of <italic>T. congolense</italic> being morphologically indistinguishable). A similar approach is applied to record the Tsavo strain of <italic>T. simiae</italic>[<xref ref-type="bibr" rid="B24">24</xref>,<xref ref-type="bibr" rid="B25">25</xref>], initially classified as another type of <italic>T. congolense</italic>[<xref ref-type="bibr" rid="B26">26</xref>]. Within <italic>T. brucei</italic>, three sub-species are recognized, among which <italic>T. b. brucei</italic> is the one with major veterinary importance. However, because of their epidemiological relevance as causative agents of sleeping sickness, the two human-infective subspecies (i.e. <italic>T. b. gambiense</italic> and <italic>T. b. rhodesiense</italic>) are also included in the Atlas of AAT if reported from non-human vertebrate hosts.</p><p>By contrast, <italic>T. godfreyi</italic>, which infects the same swine hosts as <italic>T. simiae</italic> but is less pathogenic, is not included in the database as it has only been isolated naturally from tsetse [<xref ref-type="bibr" rid="B27">27</xref>,<xref ref-type="bibr" rid="B28">28</xref>]. Also, non-tsetse-transmitted trypanosomes such as <italic>T. evansi</italic> (causing the wasting disease Surra) and <italic>T. equiperdum</italic> (responsible for dourine, a disease of equines), which have a much broader geographic distribution than AAT, are not included in the Atlas.</p><p>As a rule, efforts are also made to record in the database all types of mixed infections (i.e. animals found to be infected with more than one species/sub-species/subgroup of trypanosomes). However, refinement of this component of the database might be needed because of the challenges posed by the very high number of possible combinations of mixed infections (especially when molecular tools are used for diagnosis).</p></sec><sec><title>Diagnostic methods</title><p>A criterion of inclusiveness guided the choice of the diagnostic methods. All methods that are capable of demonstrating past or present trypanosomal infections, either directly or indirectly, were considered. These comprise parasitological diagnostics, sub-inoculation methods, immunological tests and molecular methods [<xref ref-type="bibr" rid="B29">29</xref>].</p><p>Parasitological diagnosis is predicated on the direct observation of trypanosomes in the body fluids of affected animals. In the field or in the laboratory, with the aid of a microscope, a drop of blood can be examined for the presence of trypanosomes in the wet blood film technique. Fixed blood films can be examined (Giemsa-stained thick and thin smears), and concentration techniques can be applied to increase the sensitivity of the diagnosis — i.e. the haematocrit centrifugation technique (HCT) [<xref ref-type="bibr" rid="B30">30</xref>], subsequently improved in the buffy-coat technique (BCT) [<xref ref-type="bibr" rid="B31">31</xref>]. Less utilized parasitological techniques include the miniature anion-exchange columns (MAECT) [<xref ref-type="bibr" rid="B32">32</xref>].</p><p>Sub-inoculation methods are based on the transfer of infection from a suspected case to another susceptible vertebrate host (animal sub-inoculation), to an invertebrate host (xenodiagnosis), or to an <italic>in vitro</italic> culture [<xref ref-type="bibr" rid="B29">29</xref>]. The latter category includes the kit for <italic>in vitro</italic> isolation of trypanosomes (KIVI) [<xref ref-type="bibr" rid="B33">33</xref>], originally developed for the isolation of the human infective <italic>T. b. gambiense</italic> and later applied also to AAT.</p><p>In immunological diagnosis, the detection of antibodies or antigens replaces the detection of parasites that characterizes parasitological methods. For the diagnosis of AAT these methods include the rarely used complement fixation test (CFT) [<xref ref-type="bibr" rid="B34">34</xref>], the indirect fluorescent antibody test (IFAT) [<xref ref-type="bibr" rid="B35">35</xref>], and the card agglutination trypanosomosis test (CATT) [<xref ref-type="bibr" rid="B36">36</xref>] – the latter being widely used for sleeping sickness. More widely used in the veterinary field is the enzyme-linked immunosorbent assay (ELISA), in particular the indirect ELISA for antibody detection (Ab-ELISA) [<xref ref-type="bibr" rid="B37">37</xref>]. In contrast, the antigen-detection ELISA (Ag-ELISA) [<xref ref-type="bibr" rid="B38">38</xref>,<xref ref-type="bibr" rid="B39">39</xref>] failed to live up to its early promises [<xref ref-type="bibr" rid="B29">29</xref>] and it is no longer utilized in the field of AAT diagnosis.</p><p>Molecular tools, based on the detection of nucleic acids (DNA and RNA), constitute the last category of methods for detecting livestock-infective trypanosomes. Characterized by a very high sensitivity, these tools include the DNA hybridization and most notably the polymerase chain reaction (PCR). Two groups of PCR can be distinguished in AAT diagnosis: species-specific [<xref ref-type="bibr" rid="B40">40</xref>], and multiple-species [<xref ref-type="bibr" rid="B41">41</xref>], the main advantage of the latter being a less costly and time-consuming application. Importantly, the identification of the serum resistance-associated (SRA) gene as a molecular marker of <italic>T. b. rhodesiense</italic>[<xref ref-type="bibr" rid="B42">42</xref>] enables detection of human-infective trypanosomes in non-human hosts [<xref ref-type="bibr" rid="B43">43</xref>,<xref ref-type="bibr" rid="B44">44</xref>].</p><p>The lack of specificity in the clinical signs of AAT prevents definite clinical diagnosis, which is therefore not considered in the Atlas. By contrast, the packed cell volume (PCV) is often measured in AAT epidemiological studies as a measure of anaemia, and therefore it is included in the database. If available from the data source, the average PCV is recorded for the herd as a whole, as well as separately for the AAT-positive and AAT-negative animals.</p></sec></sec><sec><title>Data processing</title><p>In the process of data extraction, each data source is analyzed independently by two persons. For a number of information items, the text of the paper is reproduced verbatim in the database. This is the case, for example, for the description of the diagnostic method, the husbandry system and the presence of recent or ongoing interventions against tsetse and AAT in the study area. This literal recording enables the full wealth of information contained in the paper to be retained. Subsequently, harmonization enables the heterogeneous descriptive information to be lumped into broad categories for easier data extraction. For example, harmonization in the description of diagnostic methods enables diagnostic-specific data subsets to be easily generated for such methods as BCT, ELISA or PCR.</p><p>Notes are taken throughout the database to capture relevant nuances and, lastly, possible questions and requests for clarifications to the authors of the papers are recorded, which have the potential to contribute to the future refinement and improvement of the database.</p></sec></sec><sec sec-type="results"><title>Results</title><p>As we write, a total of 122 peer-reviewed publications have been identified, downloaded and processed, which contain spatially-explicit data on AAT collected since January 1990 in Ethiopia, Kenya and Uganda (49, 44, and 31 papers respectively, the sum exceeding the total because a few papers have a multinational scope).

The pilot activity in Ethiopia, Kenya and Uganda is proof of concept that information is available in the literature and that technical tools are mature for continental maps of AAT to be generated and disseminated. Transparent communication of all the data sources used (Additional file <xref ref-type="supplementary-material" rid="S2">2</xref>) may enable scientists to point out supplementary scientific papers for inclusion. However, it is apparent that information gaps in numerous geographical areas will require additional, unpublished data sources to be utilized if a complete picture is to be derived.</p><p>Continued technical support by FAO and IAEA to tsetse-affected countries facilitates access to this broader base of contemporary field data on AAT (e.g. [<xref ref-type="bibr" rid="B47">47</xref>,<xref ref-type="bibr" rid="B48">48</xref>]), and it also permits dissemination of the methodology at the local level through a range of capacity development activities. The potential exists for affected countries to adopt the presented methodology and build national Atlases of tsetse and AAT, and activities in this direction are ongoing in a number of countries [<xref ref-type="bibr" rid="B49">49</xref>]. Also, data sharing tools are available through the PAAT Information System (e.g. FAO Geonetwork), which can be used to maximize dissemination of geospatial information on AAT [<xref ref-type="bibr" rid="B50">50</xref>].</p><p>Activities are ongoing at FAO to apply the presented methodology to all countries affected by nagana, and to develop the tsetse component of the Atlas. In the process of assembling data on the distribution of <italic>Glossina</italic> species, attention is also being given to trypanosomal infection in the tsetse vector, although these types of datasets are scant. Geo-referenced information on the occurrence of animal- and human-infective trypanosomes in tsetse flies will complement data on the occurrence of human and animal trypanosomoses, and will enable trypanosomal risk to be estimated from a broader perspective.</p><p>The present phase of data assembly and mapping will be followed by the application of geospatial modelling techniques in an effort to generate predictive surfaces of AAT endemicity and tsetse infestation at the national, regional and continental scales. In this process, particular attention will have to be paid to the many heterogeneities and potential sources of bias that follow from the diversity of approaches to data collection. Among these possible sources of bias we can cite the different sensitivities of the various diagnostic techniques, host susceptibility as it relates to host species, breed, age and sex, husbandry systems, trypanocidal usage, tsetse control and seasonality.</p></sec><sec sec-type="conclusions"><title>Conclusions</title><p>Developing contemporary global maps of AAT and tsetse will require substantial efforts, which can only be justified and sustained in the light of the broader objective of the Atlas initiative (i.e. to provide endemic countries with tools to better manage, analyze and share entomological and parasitological data, for improved, evidence-based decision making). To fulfil this broader objective, full engagement of and collaboration with the national animal health authorities and research institutes are crucial. In particular, the highest priority is presently being given to supporting countries planning and implementing field interventions against trypanosomosis, with a focus on projects conducted in the framework of PATTEC.</p></sec><sec><title>Abbreviations</title><p>AAT: African Animal Trypanosomosis; AU-IBAR: African Union Interafrican Bureau for Animal Resources; Ab-ELISA: Antibody-detection ELISA; Ag-ELISA: Antigen-detection ELISA; CATT: Card Agglutination Trypanosomosis Test; CFT: Complement Fixation Test; ELISA: Enzyme-Linked Immunosorbent Assay; FAO: Food and Agriculture Organization of the United Nations; GIS: Geographic Information Systems; HCT: Haematocrit Centrifugation Technique; HAT: Human African Trypanosomosis; IFAT: Indirect Fluorescent Antibody Test; IAEA: International Atomic Energy Agency; KIVI: Kit for In Vitro Isolation of Trypanosomes; MAECT: Miniature Anion-Exchange Columns; PCV: Packed cell volume; PATTEC: Pan-African Tsetse and Trypanosomosis Eradication Campaign; PCR: Polymerase Chain Reaction; PAAT: Programme against African Trypanosomosis; BCT: Buffy-Coat technique; WHO: World Health Organization.</p></sec><sec><title>Competing interests</title><p>The authors declare that they have no competing interests.</p></sec><sec><title>Authors’ contributions</title><p>GC designed and coordinated the study, and drafted the manuscript.
