The vector competence of Australian mosquitoes for yellow fever virus (YFV) was evaluated. Infection and transmission rates in Cairns and Townsville populations of and a Brisbane strain of were not significantly different from a well-characterized YFV-susceptible strain of . After exposure to 10 tissue culture infectious dose (TCID)/mL of an African strain of YFV, > 70% of and became infected, and > 50% transmitted the virus. When exposed to 10 TCID/mL of a South American strain of YFV, the highest infection (64%) and transmission (56%) rates were observed in . The infection and transmission rates in the Cairns were both 24%, and they were 36% and 28%, respectively, for the Townsville population. Because competent vectors are present, the limited number of travelers from endemic areas and strict vaccination requirements will influence whether YFV transmission occurs in Australia.
