ABSTRACT
Epizootics and yellow fever epidemics in 2008 in Brazil, Paraguay and Argentina marked a significant progression of the disease further south in the continent affecting non-vaccinated human populations. The state of Mato Grosso do Sul is located between the tropical endemic region and the subtropical epidemic region and, despite being an area recommended for vaccination since the 1980s, human and animal cases of the disease are still registered. The purpose of this study was to present the results of entomological surveys of probable sites of infection (PSI) geographically describing these areas regarding human cases and disease suspicion reported in 2008. Thirteen locations in nine municipalities were investigated. A total of 305 females of the genus Haemagogus and Sabethes and five specimens of Aedes albopictus were obtained. The genus Haemagogus was more abundant but Sabethes presented twice as many species (3 x 6) and higher distribution within the collection points. The most abundant species was Hg. janthinomys, with 102 individuals in one location. The other species found were Hg. leucocelaenus, Hg. spegazzinii, Sa. albiprivus, Sa. belisarioi, Sa. chloropterus, Sa. glaucodaemun, Sa. intermedius and Sa. soperi. It was not possible to identify predominant species in relation to environmental and geographical characteristics of the collection points. Of the nine human cases, eight corresponded to persons not resident in the State, seven of them tourists. MS features a large diversity of rural and wildlife tourist attractions where the yellow fever vectors described in this work are present. In this sense, the monitoring of vaccination coverage and flow of non-vaccinated people through the area are crucial to controlling the disease.
