Abstract

Introduction: Mosquito-borne diseases are particularly sensitive to weather conditions.

Objective: To model Aedes aegypti focality and climate indicators in Nueva Gerona, Cuba.

Methods: A descriptive cross-sectional study was conducted from 2006 to 2022 in Nueva Gerona, Isla de la Juventud. An expectation curve by months and analysis of climate indicators was used to decide on the most appropriate moment to undertake vector suppression actions. Once identified, spatial modeling and weather analysis were carried out for the same period.

Results: The expectation curve provided evidence of greater Aedes aegypti focality from June onwards; therefore, the period from March to June was defined as the most appropriate to intensify vector population suppression actions. The maps showed several hot spots with the highest risk that include the people's councils of Pueblo Nuevo, Abel Santamaría, 26 de Julio and the locality of Nazareno. Cumulative rainfall began in March (24.3 mm), April (55.4 mm), May (163.4 mm) and June (393.8 mm). Temperatures and relative humidity increased by month. Easterly winds predominated.

Conclusions: Modeling Aedes aegypti focality defined temporo-spatially and as an early warning system that the period between March and June were the most appropriate for conducting vector suppression actions, based on climate indicators that exerted favoring effects on infestation.
