Introduction: Guayaquil population has an endemic – epidemic presence of dengue and there are few studies on the historical trend of the factors that influence its behavior. Objective: To establish the historical trend of factors relate to the dynamics of dengue in the city of Guayaquil during the period 2008 - 2013. Design. Non-experimental study, longitudinal trend. Setting: City of Guayaquil, Ecuador. Material: Cases of dengue. Methods: Information on cases of Dengue, temperature, humidity and wind, Breteau index and circulating viruses were obtained. Main outcome measures: Historical trend of the factors that influence the dynamics of dengue. Results: The trend with the most cases occurred in weeks 10-24 in 2010 and 2012, with scattering points compared to the trend line. Environmental variables showed findings of moisture above 70% with high and low winds that can cause conditions...

Introduction: Nowadays, the dengue virus infection is one of the most important arboviroses in the world’s tropical and subtropical regions. Objective: To determine the evolution of the dengue virus circulating in Ecuador during the period 2000-2015. Design: Non-experimental, transversal, descriptive and correlational study. Setting: Health units of Ecuador. Participants: The samples were taken from dengue suspects with less than 5 days from the beginning of the disease. Results: In 2000, the four serotypes were present, with prevalence of DEN3 during 2001-2006 coinciding with the increase of cases in 2000, 2001 and 2005; in 2004, the DEN1 virus reappeared and, during the following years, its presence predominated between 2007 and 2012, coinciding with the increase of cases in 2010. From 2011 to 2015 three circulating viruses were present at the same time (DEN1, DEN2 and DEN4); in 2014...

Establece la tendencia histórica de los factores en la dinámica del dengue en la ciudad de Guayaquil, durante el período 2008 - 2013. Utilizando un estudio observacional, de tipo descriptivo ecológico. En sus resultados, coincide que en la época de invierno se encuentra el mayor número de casos, pero con presencia durante todo el año; y al paso de los años 2010 y 2012 fueron de mayor incidencia, con una variabilidad en su comportamiento. Las variables ambientales mostraron hallazgos, en el que a más temperatura, con humedad por encima del 70% y escasos vientos, estos provocan condiciones para que pueda existir un incremento en la transmisión de la enfermedad. Además, los picos epidémicos de dengue presentados en los dos primeros períodos de cada año se relacionan en los mismos períodos con los índices de Breteau elevados considerados de alto riesgo, pudiendo influir en la...
