Epidemiologia das encefalites por arbovírus na amazônia brasileira

Abstract: Os autores revêem os aspectos ecoepidemiológicos apresentados pelos virus da encefalite de St. Louis (SLE), encefalites equinas Leste (EEE), Oeste (WEE) e Venezuelana [subtipos III, Mucambo (MUC) e IV, Pixuna (PIX)], decorrentes dos estudos realizados em diversas áreas da Região Amazônica brasileira, especialmente ao longo das rodovias e projetos de desenvolvimento. Esses vírus são amplamente distribuídos na Amazônia e pelo menos quatro deles, EEE, WEE, MUC e SLE já demonstraram ser patógenos do homem. O diagn… Show more

“…From the serum samples obtained, 21 were seropositive for SLEV by the HI test 6 , suggesting the involvement of primates in the SLEV maintenance cycle in the Southern Cone region. SLEV was also detected in the State of Pará in Culex declarator and in migratory birds during epizootic cases observed in primates 19 , confirming the importance of these hosts in the disease cycle.…”

“…The high levels of antibodies to MAYV found in the sera of animals trapped in the City of Bonito suggest the possible circulation of this virus in this location. MAYV antibodies were also found in Callithrix argentata primates by the HI test during an investigation of Mayaro and YF outbreaks in Belterra in the State of Pará 19 .…”

“…A high prevalence of antibodies to arboviruses was observed in humans in the same study 27 . Antibodies to MAYV were also found in Callithrix argentata primates, using the HI test , during an investigation of outbreaks of Mayaro and yellow fever in Belterra, in the State of Pará, Brazil 28 . Similar results were also observed in a study of primates in the municipality of Bonito 4 .…”

“…A primeira espécie foi incriminada como vetor do vírus da encefalite de São Luís na América Central e norte da América do Sul 22 e suspeita-se que a segunda possa intervir no ciclo natural desse mesmo agente na Amazônia Brasileira 34 . Note-se que de acordo com Labarthe e cols 14 18 , podendo ter refletido na diminuição da densidade populacional de anofelinos dessa área.…”
