Climate-Driven Statistical Models as Effective Predictors of Local Dengue Incidence in Costa Rica: A Generalized Additive Model and Random Forest Approach
Vásquez Brenes, Paola Andrea; Loría García, Antonio; Sánchez Peña, Fabio Ariel; Barboza Chinchilla, Luis Alberto (2019-12)Climate has been an important factor in shaping the distribution and incidence of dengue cases in tropical and subtropical countries. In CostaRica, a tropical country with distinctive micro-climates, dengue has been endemic ... -
Comparative analysis of dengue versus chikungunya outbreaks in Costa Rica
Sánchez Peña, Fabio Ariel; Barboza Chinchilla, Luis Alberto; Burton, David; Cintrón Arias, Ariel (2018-06)For decades, dengue virus has been a cause of major public health concern in Costa Rica, due to its landscape and climatic conditions that favor the circumstances in which the vector, Aedes aegypti, thrives. The emergence ... -
