I had no plans to attend, Zika or no Zika. Last time I attended an Olympic event was in 1984, when they were in LA (and I was still living down in Southern CA during the summers).
Is postponement an option? What if they were pushed back a couple of years? Maybe by then we'll have a vaccine, or at least have a better understanding of which procedures reduce the risk of its spread.
But I honestly am not sure which approach is best. We still don't have a good idea what kind of threat this may be if some people contract the virus and travel to their various homes with it, and we don't (yet) have a vaccine or know for sure how to eliminate the risk of bites.
But cancellation, or even postponement, would screw over athletes who have worked and trained for this once in a lifetime opportunity, and it will cost Brazil all that money they've already sunk in building the various venues. Moving it would cause the same problem for Brazil, but at least it would give the athletes a chance to compete. But it's unprecedented to do this, isn't it, and who would be able to host them at such short notice?
So if postponement isn't an option, then I'm leaning towards holding them but being extremely draconian about protective clothing, bug spray, and so on.
But something tells me that attendance will be way lower than originally anticipated, and this may mean that Brazil will take an even bigger bath financially than hosting countries usually do.
I wouldn't go to Brazil regardless. Seems hot. I hate hot. I'd go to pretty much any winter games, anyplace. Summer, not so much.
Rio is below the equator, so our summer is actually their winter. So the Zika threat will be less at that time of year. Still, it's in the tropics, so I'm guessing it's going to be quite humid and warm year round.
