Abstract
RODRIGUEZ, Rodrigo Marín and RIOS, Mariela Díaz. Sitios de cría de Aedes aegypti (Linnaeus) en el cantón de Parrita, provincia de Puntarenas, Costa Rica, junio 2013. Rev. costarric. salud pública [online]. 2015, vol.24, n.2, pp.136-142. ISSN 1409-1429.
Introduction: Dengue fever represents the main vector-borne illness in Costa Rica. The area called Parrita has been one of those with the highest reporting of dengue during the last few years. During 2013, in Parrita, there were 1120 reports of this illness and thus it came to occupy the 18th spot among the areas with the highest reporting of cases in the whole of Costa Rica. Control of dengue requires comprehensive knowledge of the main vector, Aedes aegypti, since this insect uses a large variety of artificial containers for its breeding.
Objectives:
To identify and describe the main breeding sites for Ae. aegypti in the area of Parrita which was in the midst of a full-blown outbreak of dengue fever during epidemiological weeks' number 23 and 24 in the year 2013.
Materials and Methods:
Entomological sampling was performed by 29 employees of the Integrated Vector Control Unit of the Ministry of Health. The presence of at least one Ae. aegypti larva in any of the containers was considered enough to designate this as a "positive" container.
Results:
During the study period, 918 breeding sites or sites positive for the vector were identified among a total of 5 027 homes visited. The presence of Ae. aegypti was confirmed in all the localities surveyed in the area of Parrita. The most frequent types of breeding sites were as follows: cans, buckets, tires, mechanical garbage and different types of tanks.
Discussion:
The conclusion is that there is evidence to suggest that the control of Ae. aegypti should be done in a comprehensive fashion with emphasis of inter-sectoral co-ordination due to the variety and multi-causality of the breeding sites.
