If Olympics increase annual tourism by 10% as I have seen elsewhere and in this thread, then that effectively doubles the tourism to Rio for the duration of the Olympics. As others have pointed out, there are poor countries that have trouble eradicating mosquito borne disease (think malaria, which is transmitted via the same species as zika) that do not currently have zika. Increasing the speed of the spread of the disease does not seem logical given that we do not even have a vaccine. Moreover, this is a rapidly evolving disease which is also sexually transmitted. I would not recommend traveling to Rio or other Zika-invested countries right now. You can't just get vaccinated before travelling. Doubling the tourism to Brazil for a month seems like a bad idea at best, hazardous at worst.
