HOYOS RIVERA, Antulio; PEREZ RODRIGUEZ, Antonio  e  HERNANDEZ MELENDREZ, Edelsys. Features of clinical significance of dengue in San Mateo community, Anzoátegui, Venezuela (2005-2008). Rev Cubana Med Gen Integr [online]. 2011, vol.27, n.4, pp.558-565. ISSN 0864-2125.

Introduction: The diagnosis of dengue cases has been limited due to difficulty to identify early the acute febrile cases corresponding to this disease, obstructing its epidemiologic control. Objective: To compare the clinical features of the cases diagnosed in the integral diagnostic center came spontaneously with those infected identified by active screening in a prevalence study of dengue in community. Methods: A comparative and descriptive clinical study was conducted in 50 patients presenting symptoms of dengue came spontaneously (cases of passive study) from 2005 to 2006 with those of dengue identified by a point prevalence study (active search of cases) conducted from May, 2007 to May, 2008. As a summary measure of the study variables percentage was used. Results: The comparative analysis showed that the passive study of the total of 50 cases, only the 20 % was IgM positive, which is higher than results of the prevalence study demonstrating the presence of 80 positive patients from a total of 535 study persons for a 14.95 %; however, it not covered all the clinical disease range. The typical symptomatology of the dengue is the more frequent in both studies. Conclusions: The seroprevalence studies guarantee the knowledge of the real magnitude of this problem. The proposal clinical spectrum for the positive IgM covers all the possible symptomatology allowing a better disease control.
