Due to the rapid geographic spread of the Aedes mosquito and the increase in
dengue incidence, dengue fever has been an increasing concern for public health
authorities in tropical and subtropical countries worldwide. Significant
challenges such as climate change, the burden on health systems, and the rise
of insecticide resistance highlight the need to introduce new and
cost-effective tools for developing public health interventions. Various and
locally adapted statistical methods for developing climate-based early warning
systems have increasingly been an area of interest and research worldwide.
Costa Rica, a country with micro-climates and endemic circulation of the dengue
virus (DENV) since 1993, provides ideal conditions for developing projection
models with the potential to help guide public health efforts and interventions
to control and monitor future dengue outbreaks
