Common patterns between dengue cases, climate, and local environmental variables in Costa Rica: A Wavelet Approach

no code implementations3 Jan 2023 Yury E. Garcia, Shu-Wei Chou-Chen, Luis A. Barboza, Maria L. Daza-Torres, J. Cricelio Montesinos-Lopez, Paola Vasquez, Juan G. Calvo, Miriam Nuno, Fabio Sanchez

In this study, we conducted a wavelet time series analysis of weekly climate, local environmental variables, and dengue cases (2001-2019) from 32 cantons in Costa Rica to identify significant periods (e. g., annual, biannual) in which climate and environmental variables co-varied with dengue cases.

We elicit prior distributions of the effective population size, the dynamical system initial conditions and infectious contact rate, and use Markov Chain Monte Carlo sampling to make inference and prediction of quantities of interest (QoI) at the onset of the epidemic outbreak.

Recent research on accelerated gradient methods of use in optimization has demonstrated that these methods can be derived as discretizations of dynamical systems.
