A geopositioned, evidence-graded, pan-species compendium of Mayaro Virus occurrence

Mayaro Virus (MAYV) is an emerging health threat in the Americas that can
cause febrile illness as well as debilitating arthralgia or arthritis. To
better understand the geographic distribution of MAYV risk, we developed a
georeferenced database of MAYV occurrence based on peer-reviewed
literature and unpublished reports. Here we present this compendium, which
includes both point and polygon locations linked to occurrence data
documented from its discovery in 1954 until 2022. In the associated data
descriptor manuscript (https://doi.org/10.1038/s41597-023-02302-z), we
describe all methods used to develop the database including data
collection, georeferencing, management, and quality-control. We also
describe a customized grading system used to assess the quality of each
study included in our review. The result is a comprehensive,
evidence-graded database of confirmed MAYV occurrence in humans, non-human
animals, and arthropods to-date, containing 262 geo-positioned occurrences
in total. This database – which can be updated over time – may be useful
for local spill-over risk assessment, epidemiological modelling to
understand key transmission dynamics and drivers of MAYV spread, as well
as identification of major surveillance gaps.
