Somebody would travel to say Brazil, get Zika virus there and come back to Cairns, or a South American traveller who's visiting Australia is infected with Zika virus. If they're bitten by the mosquitoes over here, the mosquitoes get infected and can potentially transmit the virus.
It was suspected that mosquitoes had brought the disease to Yap Island. But Vasilakis says a previously infected human visitor could have been bitten by local mosquitoes, which then spread the virus.
There is "very high suspicion" of a link between the Zika virus and microcephaly in French Polynesia, said Dr. Didier Musso, an infectious disease specialist at the archipelago's Institut Louis Malardé – though he said additional research was still needed. Last November French Polynesian officials reinvestigated an outbreak of Zika that lasted from October 2013 to April 2014. They reported finding an unusual increase – from around one case annually to 17 cases in 2014-15 – of unborn babies developing "central nervous system malformations," a classification that includes microcephaly.
