Introduction: The Americas represent a special scenario for the Leishmaniasis, due to the high number of
cases (2/3 parts of the worldwide disease burden) and the number of species that are circulating in different
countries. Currently, there are not available database that cluster the species present in each country,
neither the micro geographical distribution. Objective: The aim of this work was to develop a database and
interactive map of the distribution of Leishmania species reported in the Americas, as the samples, host,
and techniques used for its identification. Materials and Methods: We made a systematic review in 3
different databases of the Leishmania species reports in the Americas. We extracted information about the
sample type and location, host, identification techniques and species involved. An interactive map was
made using Shiny app in RStudio Results: 487 articles were obtained, where the authors
identified Leishmania species, with 1527 georeferenced points in 16 countries of the American continent.
Brazil is the country with most circulating species (16) followed by Colombia and Ecuador. The skin biopsy
was the most used sample in the researches (51%). The map allows the visualization of the results in a
dynamic way, crossing different variables to determine the territories at risk, as the sites that requires
stronger surveillance strategies. Conclusion: The distribution of Leishmania species in the Americas
requires a constant update due to the burden disease in the continent. The surveillance epidemiologic
systems must be stronger, offering tools that allows the visualization of that distribution in a dynamic way,
with the purpose of stratifying the risk and improve the prevention policies and the control of the disease in
the territories
