| contents | Dengue and dengue and vector behaviour in Cáqueza, Colombia, 2004 Hernán Rodríguez G. Fernando de la Hoz R. Salud Colombia entomology l indicators Aedes aegypti seroprevalence Objective Describing the behaviour of dengue and its vector in Cáqueza,Colombia (1 746 masl) by serological, entomological and virological monitoringbetween March and June 2004.Methods Two types of study were carried out. One was a cross-sectionalstudy for serologically monitoring the population and taking entomological indicators;participants were selected from the general population by randomconglomerate sampling. The second study consisted of monitoring febrilecases suspected of dengue during a four-week period. Vector behaviour(bite-rate and hours of activity) was also included by using the landing-onhumanstechnique; a rubbish-collecting day was run during the same periodfor evaluating this interventions short-term effectiveness.Results Total prevalence of infection by dengue (IgG positive) was 23,3 % in252 people examined in the surveyed population. Household infestation indexwas 32,9 %; deposit index was 8,4 %; and Breteau index was 43,9. Followingthe rubbish-collection day, the infestation index became reduced by56 % (14,5 % post-intervention), deposit index by 43 % (4,8 % post-intervention)and Breteau index by 59 % (17,9 % post-intervention). Two of the febrilepatients (n=83) were IgM positive.Conclusions The study showed that dengues urban vector can reach dangerouslevels of infestation above 1 700 masl; however, a deeper study of itsbionomy is needed at these heights above sea-level during different times ofthe year for improving knowledge regarding climatic and environmental factorsaffecting their efficiency as vector in these conditions. 2005 artículo científico 0124-0064 https://www.redalyc.org/articulo.oa?id=42270101 en http://www.redalyc.org/revista.oa?id=422 Revista de Salud Pública application/pdf Universidad Nacional de Colombia Revista de Salud Pública (Colombia) Num.1 Vol.7 |
