Every day hundreds of thousands of people fly in and out of Brazil to and from all corners of the world. Rio Galeão alone handles 17m passengers per year, much more than the total number of Olympic tickets available (most of which are sold to Brazilians, and most of the attendees buy more than just one).
Nobody I can find is giving credible numbers that show the olympics will constitute a significant increase to affected areas over the year as a whole (edit: as adevine points out, below, the article puts the increase at c 0.0025), nor that travel is currently only from a handful of places worldwide.
If international travel to Rio is a public health problem, then focussing on the olympics is pure tokenism.
