But will you at least concede that THIS is what should have been the focus of the article? While perfectly valid, all of the scientific discussion around Zika is mostly irrelevant to the point the author was trying to make -- the true variable of interest is how the games shape the quantity of visitors and the distribution of those visitors around the world. But there's hardly a line in the article about that -- just the 500,000 number is thrown around with absolutely no citation.

Instead,the article does some of the worst things we'd expect from scientists with sentences like "All it takes is one infected traveler" -- this is fear-mongering and irresponsible and the author should be ashamed of that comment.

I maintain that it is not a careful, reasoned argument about the issue.

I'm sorry, but there seems to be a bit of a logical disconnect here. This looks like a knee-jerk pattern match on the "all it takes" phrase. My understanding is that this is factual in this case. That is how it works with a lot of diseases -- with many kinds of self-replicators -- all it takes is one. That is how it works with various insect and fungal blights that have ravaged California forests. A public awareness of the relative risks is a public good.

Single patients flown to the US from the Ebola stricken regions did not spread infection, because of the particulars of infection mechanisms. Zika can be spread by mosquito. If the Olympics increase the traffic to resource-thin countries with populations of the right kind of mosquito, this should be considered carefully.
