“…Entre el 2005 y el 2007, se evaluó en un estudio multicéntrico el estado de la resistencia a insecticidas en los principales vectores de dengue y malaria en 12 departamentos del país y se reportó que, aproximadamente, el 70 % de las poblaciones de Ae. aegypti evaluadas fueron resistentes al temefós (10,11). En otros países de América Latina, como Argentina (12,13), Brasil El mosquito Aedes (Stegomyia) aegypti, Linnaeus 1762, es reconocido como el artrópodo más importante en la transmisión de los virus del género Flavivirus responsables del dengue y la fiebre amarilla urbana en humanos (1).…”

“…En varias evaluaciones hechas en el país, se ha informado que la mayoría de las poblaciones de Ae. aegypti son sensibles al malatión (10,11,21). Sin embargo, en países como Cuba, Panamá y Venezuela (19,22,23), se ha encontrado una resistencia incipiente a este insecticida.…”

En otros países de la región, como la Guyana Francesa (25), México (26) y Perú (27), así como en el occidente venezolano (23), también se ha reportado resistencia a la deltametrina, y solo en Cuba y Panamá (19,22,28), se ha encontrado resistencia entre moderada y alta al metil-pirimifós.…”

Introduction:Mosquito salivary proteins are able to induce an antibody response that reflects the level of human-vector contact. IgG antibodies against dengue virus (DENV-IgG) are indicators of previous exposure. The risk of DENV transmission is not only associated to mosquito or dengue factors, but also to socioeconomic factors that may play an important role in the disease epidemiology. Objective: To determine the effect of the presence of Aedes aegypti mosquitos in different stages in households and the history of dengue exposure on vector-human contact determined by the level of anti-salivary protein antibodies in people living in a Colombian endemic area. Materials and methods: A pilot study of 58 households and 55 human subjects was conducted in Norte de Santander, Colombia. A questionnaire for socioeconomic factors was administered and houses were examined for the presence of Ae. aegypti specimens in the aquatic stages. The level of DENVIgG antibodies (DENV-IgG), in addition to IgG and IgM anti-Ae. aegypti salivary gland extract (SGE) antibodies (SGE-IgG, SGE-IgM) were evaluated by ELISA using blood collected in filter paper. Results: We found a significant higher level of SGE-IgG antibodies in subjects living in houses with Ae. aegypti in aquatic stages. We also found a higher concentration of SGE-IgG antibodies in people exposed to DENV, a positive correlation between IgM-SGE and IgG-DENV and a negative correlation with IgG-SGE. Conclusion: Anti-salivary proteins antibodies are consistent with the presence of Ae. aegypti aquatic stages inside houses and DENV-IgG antibodies concentrations.

In Colombia, a country with a population of 46,722,777 distributed in 1,103 municipalities, the disease has become endemic with frequent outbreaks 6 . Six of 32municipalities showed 55.36% (20,394) of the cases of the fi rst nine months of 2012. Currently all four serotypes circulate throughout the country 7 . A campaign to eradicate Ae. aegypti began in the early 1950s, and the country was said to be free of infestation by 1952. Columbia's Ministry of Health (MoH) operates under the National Plan of Basic Attention Beginning in 2006, the MoH adopted a national integrated control strategy with intersectorial, multidisciplinary, and community participation and a vector control program based mainly on the use of insecticides.We compared levels of consciousness and conduct in one Brazilian and four Colombian communities. These fi eld studies were realized in two stages: I) An entomological survey using the House Index and Breteau Index. In Brazil this survey was done bimonthly over one year (2008); in Colombia, this survey was conducted at three times, time zero (TO), time one (T1), and time two last intervention (T2), from 2008-2010; II) A survey of knowledge, attitudes, and practices of a sample of residents, using a standardized household survey about knowledge of the disease, activities of prevention, and control of vectors, water supply, sanitation, and home reservoirs in Latin America.The Brazilian study site was the neighborhood Santa Rosa in the municipality of Cabo de Santo Agostinho, State of Pernambuco, which is a tourist and port complex of 448 square km with a population of 152,997, 87.9% of whom are urbanized, and with relative socioeconomic homogeneity. Its 813 domiciles manifest a 50% dengue incidence with a ± 5% confi dence interval based on a 263-domicile sample 2 . The N=263/813 households were calculated with an estimated 50% incidence at a ± 5% error interval. The study covered 852 persons, with a mean of four persons per domicile, and the study period was [2007][2008][2009]. In Colombia, four neighborhoods in the municipalities of Apartado (La Alborada and La Arboleda) and Carepa (Obrera and Cadena) in Antioquia State were chosen
