%X objective: describing the behaviour of dengue and its vector in c¨¢queza, colombia (1 746 masl) by serological, entomological and virological monitoring between march and june 2004. methods: two types of study were carried out. one was a cross-sectional study for serologically monitoring the population and taking entomological indicators; participants were selected from the general population by random conglomerate sampling. the second study consisted of monitoring febrile cases suspected of dengue during a four-week period. vector behaviour (bite-rate and hours of activity) was also included by using the landing-on-humans technique; a rubbish-collecting day was run during the same period for evaluating this intervention£¿s short-term effectiveness. results: total prevalence of infection by dengue (igg positive) was 23,3 % in 252 people examined in the surveyed population. household infestation index was 32,9 %; deposit index was 8,4 %; and breteau index was 43,9. following the rubbish-collection day, the infestation index became reduced by 56 % (14,5 % post-intervention), deposit index by 43 % (4,8 % post-intervention) and breteau index by 59 % (17,9 % post-intervention). two of the febrile patients (n=83) were igm positive. conclusions: the study showed that dengue£¿s urban vector can reach dangerous levels of infestation above 1 700 masl; however, a deeper study of its bionomy is needed at these heights above sea-level during different times of the year for improving knowledge regarding climatic and environmental factors affecting their efficiency as vector in these conditions.
