A scoping review of published and gray literature related to asymptomatic <jats:italic>Leishmania<\/jats:italic> infection was conducted; retrieved citations were screened based on predefined eligibility criteria, and relevant data items were extracted from eligible articles. The analysis is descriptive and is presented using tables, figures, and thematic narrative synthesis.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>We conducted a screening of 3008 articles, of which 175 were selected for the full review. Of these articles, we selected 106 that met the inclusion criteria. These articles were published between 1991 and 2021, and in the last 5\u00a0years, up to 38 articles were reported. Most of the studies were conducted in Brazil (26%), Spain (14%), India (12%), Bangladesh (10%), and Ethiopia (7%). Of the studies, 84.9% were conducted in the immunocompetent population, while 15.1% were conducted in the immunosuppressed population (HIV, immunosuppressive drugs, and organ transplantation population). We report 14 different techniques and 10 strategies employed by researchers to define asymptomatic <jats:italic>Leishmania<\/jats:italic> infection in an endemic area.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>The definition of asymptomatic <jats:italic>Leishmania<\/jats:italic> infection is not unified across the literature, but often includes the following criteria: residence (or extended stay) in a <jats:italic>Leishmania<\/jats:italic>-endemic area, no reported signs\/symptoms compatible with leishmaniasis, and positive on a combination of serological, molecular, cellular, and\/or parasitological tests. Caution is recommended when comparing results of different studies on the subject of asymptomatic infections, as the reported prevalence cannot be confidently compared between areas due to the wide variety of tests employed by research groups. More research on the importance of asymptomatic immunosuppressed and immunocompetent <jats:italic>Leishmania<\/jats:italic>-positive populations in leishmaniasis epidemiology is required.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Graphical Abstract<\/jats:title>\n                \n              <\/jats:sec>","DOI":"10.1186\/s13071-021-05129-y","type":"journal-article","created":{"date-parts":[[2022,1,5]],"date-time":"2022-01-05T00:10:47Z","timestamp":1641341447000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":43,"title":["Identification of asymptomatic Leishmania infections: a scoping review"],"prefix":"10.1186","volume":"15","author":[{"given":"Ana Victoria","family":"Ibarra-Meneses","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Audrey","family":"Corbeil","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Victoria","family":"Wagner","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chukwuemeka","family":"Onwuchekwa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4834-4956","authenticated-orcid":false,"given":"Christopher","family":"Fernandez-Prada","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2022,1,5]]},"reference":[{"key":"5129_CR1","first-page":"1","volume-title":"Control of the leishmaniases.
