Yes but catching this in Brazil and pandemic are not necessarily linked. In this article I didn't see any reference that being infected in brazil will mean is a mosquito or other transmission in your home country is likely. I know in my country of Australia only one species of mosquito can potentially carry this virus, and they exist is in a remote region itself even if they can get this virus from the human that caught it and returned to a non-infected country.

Do you see where I'm coming from? I'm not saying this couldn't be a point to spread this virus around the world. However I'm not seeing any information that confirms this is a real risk other than people from around the world will be going into a live infection region. It takes much more that people simply visiting this area to make this into a Zika virus pandemic.
