an epidemiological analysis of the forms and distribution of dengue fever in brazil and worldwide was carried out. the national program of dengue control (npdc) was evaluated based on the data available at "diagdengue" an official computerized information system allowing to follow-up the implantation and impact of the program. a factorial analysis was performed by means of a set of indicators contributing to variability. the indicator scores were added and the cities demanding for prior attention of the npcd were classified for the construction of an index, which is presented three-monthly for every state, with intervals distributed between 0 and 9. the implantation of the ncpd is irregular. cities with bad implantation are predominating in the north and northeast of the country. in the second analysis, socio-economic variables of the selected cities were added. for the association tests these cities were classified into two groups: "bad" and "good/very good", based on the association of the index of building infestation informed in the fad (yellow fever and dengue) database and the constructed index. associations were verified based on variance analysis, trend test and trend estimate. it was observed that cities with low rates of illiteracy, efficient garbage collection and high ratio of sanitary installations are correlated with a good classification of the city according to diagdengue.
