This is getting into an extremely pedantic argument, but here's an article from January of this year suggesting that the reservoir has always been considered to be humans, whereas mosquitoes would be the transmission vector.

The WHO also notes that Zika can be transmitted sexually.

Stepping away from the pedantry, the core of your argument is "who gives a fuck, we're fighting the good fight against AN ENTIRE SPECIES OF INSECT, if only those silly anti-science people would let us do it right." My argument is this fight is retarded, and a massive waste of our limited resources, and it would've been far simpler and cheaper to just restrict travel or have mandatory quarantine procedures for anyone coming from the regions with documented outbreaks. Like you would do for any outbreak of a dangerous and easily transmitted disease.
