| Abstract | Background: Brazil has the fourth highest prevalence of malaria of all countries in the Americas, with an estimated
42 million people at risk of contracting this disease. Although most cases occur in the Amazon region, cases of an
autochthonous nature have also been registered in the extra-Amazonian region where Anopheles aquasalis and An.
albitarsis are the mosquito species of greatest epidemiological interest. In 2019, the municipality of Conde (state
of Paraíba) experienced an epidemic of autochthonous cases of malaria. Here we present preliminary results of an
entomological and case epidemiology investigation, in an attempt to correlate the diversity and spatial distribution of
species of Anopheles with the autochthonous cases of this outbreak of malaria.
Methods: Case data were collected using case report forms made available by the Conde Municipal Health Depart-
ment. The entomological survey was carried out from July to November 2019. The various methods of capture
included the use of battery-powered aspirators, mouth aspirators, Shannon traps, BG-Sentinel traps (with and without
dry ice) and CDC light traps. Captured mosquitoes were separated, packaged and sent to the laboratory for sexing
and molecular identification of the various species of anophelines. The data were tabulated and analyzed using Micro-
soft Excel. Spatial analysis of the data was performed using ArcGis 10 software.
Results: In 2019, 20 autochthonous cases and one imported case of malaria caused by Plasmodium vivax were
diagnosed, with three cases of relapses. A total of 3713 mosquitoes were collected, of which 3390 were culicines and
323 were anophelines. Nine species of genus Anopheles were identified, with the most abundant being An. aquasalis
(38.9%), followed by An. minor (18.2%) and An. albitarsis (9.0%). Spatial analysis of the data showed that the area could
be considered to be at risk of malaria cases and that there was a high prevalence of Anopheles. | en_US |
