Abstract

Dengue fever is an acute disease caused by dengue virus and transmitted through the Aedes aegyti mosquito. Currently is one of the major global issues of public health. The aim of this study was to describe the epidemiological indicators of dengue in the city of Santarém, Pará, in the period from 2013 to 2016. The work was developed from data provided by the Information System of reportable diseases (SINAN), provided by Municipal Health of Pará (SEMSA). The variables analyzed were seasonal periodicity, age group, sex, area of residence, numbers of buildings surveyed and LIRAa action with numbers of deposits where there are the greatest evidence of larvae. The results showed a decrease in the number of cases of the disease over the period studied, and one of the factors considered paramount for this was the effectiveness of the transfer of information to the population, vector control and that there is inconsistency between the years worked. The year of highest number of confirmed cases was in 2013, and the month with highest incidence was February; It was observed that individuals affected by the disease, were those of the female gender, with 55%; the age groups most affected were those observed between individuals from 20 to 39 years for (39%) of cases; the urban sector was the most infested by disease with percentage of 85% of the cases. During this period, a total of 1,302,676 households was marked for inspection, taking 216 buildings declined, 203,133 were closed, and of these, 3,878 were recovered. Thus concludes that the distribution of reported cases of the disease points to an increase in winter precipitation in the Amazon, where there is high, temperature and humidity, conditions favourable to the proliferation of Aedes aegypti; therefore also awareness of the population and the importance of strengthening the work of the LIRAa. Thus, it is concluded that the distribution of the reported cases of the disease points to an increase in the Amazonian winter period, where there is high rainfall, temperature and humidity, conditions favorable to the proliferation of Aedes aegypti, important data for the planning of public strategies to combat mosquito vector.
