Abstract

Background: Dengue is an endemic disease in this municipality, epidemics were recorded in 2010, 2014, 2018 and 2022. Despite being endemic, it does not have a focus that allows prioritizing actions. The objective of this research was to stratify the risk of dengue in the municipality of San José del Guaviare in 2022, through the use of epidemiological, entomological, socioeconomic and environmental variables for the planning of prevention and control actions.

Methods: A descriptive cross-sectional study was carried out. The level of risk for dengue in the neighborhoods of the municipality was categorized, integrating the persistence and cumulative incidence of dengue, Aedes aegypti pupal index, socioeconomic stratum, and access to drinking water. The categorization of each of the variables was carried out by tertiles, measures of central tendency (mean, median) were calculated. For its analysis, the information was processed and organized into tables and risk cartography.

Results: In the entomological variable, 43.5% (10/23) of the neighborhoods had a high rate of Aedes aegypti pupae. In the epidemiological variable, 52.3% (23/44) of the neighborhoods were categorized as having high transmission. In the environmental variable, 76.2% (32/42) of the neighborhoods were categorized as a medium risk level. According to the socioeconomic variable, 83.3% (35/42) of the neighborhoods were categorized as high risk. By integrating the variables analyzed, the neighborhoods were categorized for dengue transmission as: very high risk 23.4% (11/47), high risk 31.9% (15/47), medium risk 8.5% (4 /47) and low risk 34.0% (16/47).

Conclusions: In the final integration of risk, those neighborhoods that were classified as very high and high risk for dengue transmission should focus on the control, promotion and prevention actions of the municipality. Continue with the stratification in seasonal periods due to changes in the ecological conditions of the vector and transmission dynamics.
