Aedes albopictus em área rural do Brasil e implicações na transmissão de febre amarela silvestre

Abstract

Larvae and adult forms of Aedes albopictus were found during ecological study of anopheline mosquitos in the rural zone of the state of Mato Grosso do Sul in Brazil. This occurrence was registered, for the first time in Brazil, in an enzoootic area if sylvatic yellow fever virus. This implies a potential risk of the transfer of this virus to an urban area infested with Aedes aegypti.

“…albopictus has demonstrated a high capability for utilizing artificial breeding areas within Brazilian territory, without abandoning natural ecotopes. 2 Its epidemiological importance in the transmission of the dengue virus is recognized in rural and urban areas in Asia, as well as its participation in the transmission of Asian encephalitis. 4 Even though it is not yet clear what effect the presence of Ae.…”

“…Portanto, não se pode descartar a possibilidade da transmissão local da dengue e da febre amarela silvestre por essa espécie (Gomes et al, 3 1999), evidenciando a necessidade de estudos mais detalhados acerca de isolamento de vírus em populações naturais, bem como de sua capacidade vetorial para os arbovírus.…”
