DIEGUEZ FERNANDEZ, Lorenzo et al. Entomological study of a case of dengue introduced into Camagüey. AMC [online]. 2011, vol.15, n.2, pp.312-324. ISSN 1025-0255.

Background: the growing outbreaks of dengue complicate the deteriorated epidemiologic worldwide situation, which is favored by the presence of determining macrofactors for transmission. Objective: to evaluate the entomological results during the control of a dengue’s case introduced into Camagüey in July 2010. Methods: a descriptive longitudinal retrospective study was performed, in order to refer the main entomological actions, as well as its effectiveness in the control of the epidemiologic event. Results: values of Aedes´index were beyond of what is permissible in the first three cycles of work, with high values of Breteau rate compared to House rate that is why there was species´ dispersion. The municipal quality control contributed to greater collections, with a proportion of a larval sample/20,3 inspected houses and adult's sample/426,5 inspected houses. Low tanks, cisterns and barrels with the vector stands out, being the 52,63 % permanent, useful and no modifiable according to the population's opinion. If the population were carried out family inspection, 89,47 % of positive water tanks could be avoided. Two blocks repeated in two occasions and another two or three times. Conclusions: gained experiences in the focal treatment, proved to be efficacious in the anti-vectorial control in the faced of the notification of a case of dengue introduced, which together with extrasectorial support, it turned out to be key in the successful confrontation of the event in the short possible time.
