However, there is considerable YFV movement from Brazil to Venezuela and between Trinidad and Venezuela.
متن کاملFirst evidence of natural vertical transmission of yellow fever virus in Aedes aegypti, its epidemic vector.

Among the 22 species captured, Aedes aegypti was the most common. 'Wild' vectors of YF were also captured, including A. fu...

1. By the bites of stegomyia mosquitoes carrying neurotropic yellow fever virus, encephalitis has been produced both in white mice and in rhesus monkeys. 2.
