Febre amarela

Abstract: Resumo A febre amarela é doenca infecciosa não-contagiosa causada por um arbovírus mantido em ciclos silvestres em que macacos atuam como hospedeiros amplificadores e mosquitos dos gêneros Aedes na África, e Haemagogus e Sabethes na América, são os transmissores. Cerca de 90% dos casos da doença apresentam-se com formas clínicas benignas que evoluem para a cura, enquanto 10% desenvolvem quadros dramáticos com mortalidade em torno de 50%. O problema mostra-se mais grave em África onde ainda há casos urbanos. Na… Show more

“…13 In the Amazon region and in other endemic areas in Brazil, epizootic outbreaks have been reported every fi ve to seven years. 18 This periodicity is likely due to renewal of non-human primate populations essential for viral amplifi cation, which does not occur with vector population alone (Haemagogus and Sabethes mosquitoes) even considering the possibility of transovarial or vertical transmission.…”

“…leucocelaenus. 18,19 The former is the main vector of yellow fever in endemic areas (where vaccine is recommended) and in the state of São Paulo; 3-5,13 but it has not been found in southern Brazil. It is a mosquito with strict host specifi city for wild animals, indicating that virus transmission occurs within or near forested areas.…”

“…Immunoenzymatic assays for arbovirus studies were introduced in Brazil in 1984 for the diagnosis of human Rocio virus infections in sera collected in 1975 and 1976 from patients with clinical encephalitis 14,15 , and later for the diagnosis of yellow fever virus infection 6,24,25 .…”

“…chloropterus foi observado em laboratório em bambus com pequeno furo 2 ; a fêmea lança os ovos em vôo, através dos orifícios, e o autor considerou provável que tal comportamento ocorra em outros mosquitos que na natureza se desenvolvem em bambus. Mosquitos deste gênero, além de Haemagogus, têm sido incriminados como vetores de vírus de febre amarela silvestre 11 .…”
