Abstract
LEDEZMA ACEVEDO, Juan Gabriel; RODRIGUEZ CARDENAS, Natalia and URENA PICADO, Johnny. Digital cartographic tools in surveillance of diseases transmitted by Aedes spp;Case in Costa Rica. Rev. costarric. salud pública [online]. 2018, vol.27, n.1, pp.87-101. ISSN 1409-1429.
Aedes mosquito, because of it´s capability for spreading several virus, and it´s wide distribution at the American Continent, has generated epidemics of dengue, chikungunya, yellow fever and zika. Epidemic surveillance of these vector transmitted diseases, using free Geographic Information Systems and digital programs, has become into a great partner of Public Health departments.
Objective:
This study describes the practical use of free software of satellite image and free Geographic Information Systems, for the surveillance of Aedes spp transmitted diseases, in a Costa Rican Aedes endemic location.
Methods:
It is a case study developed at one local office, of Ministry of health in Costa Rica, geo locating the reported cases of dengue, zika, chikungunya from 2013 to 2016.
Results:
The achievement of position marks representing the house of all the cases reported, in a digital database of points and layers. Improvement in epidemic surveillance, thanks to the use of the selected programs that permitted to identify the conglomerates of cases at the neighborhoods, and the higher priority intervention zones.
Discussion:
The programs used, helped to visualize planned routes for the execution of social movement actions, and operational plans. Thanks to the image quality and the easy interactive interface, free Software selected, resulted into a useful tool for the surveillance of Aedes spp. transmitted diseases in the case of the public health department of Nandayure, from Guanacaste province of Costa Rica.
