Chagas is a potentially fatal chronic disease affecting large numbers of
people across the Americas and exported throughout the world through human
population movement. It is caused by the Trypanosoma cruzi parasite, which
is transmitted by triatomine vectors to humans and a wide range of
alternative host species. The database described here was compiled to
allow the risk of vectorial transmission to humans to be mapped using
geospatial models. The database collates all available records, published
since 2003, for prevalence and occurrence of infection in humans, vectors
and alternative hosts, and links each record to a defined time and
location. A total of 16,802 records of infection have been extracted from
the published literature and unpublished sources. The resulting database
can be used to improve our understanding of the geographic variation in
vector infection prevalence and to estimate the risk of vectorial
transmission of T. cruzi to humans.
