Dengue emergence in the temperate Argentinian province of Santa Fe, 2009-2020

Abstract

Dengue disease is found in tropical and subtropical climates and within the last decade it has extended to temperate regions. Santa Fe, a temperate province in Argentina, has experienced an increase in dengue cases and virus circulation in the last decade, with the recent 2020 outbreak being the largest since dengue transmission was first reported in the province in 2009. The aim of this work is to perform a description of spatio-temporal fluctuations of dengue (DENV) cases from 2009 to the present in Santa Fe province. The data presented in this work provide a detailed description of dengue virus transmission for Santa Fe province by department. This information is useful to assist in better understanding the impact of ongoing dengue emergence in temperate regions across the world. Indeed, this work provides data useful for future studies including those investigating socio-ecological, climate, and environmental factors associated with dengue transmission, as well as those investigating other variables related to the biology and the ecology of vector-borne diseases.
