Generally, unless blown up into the air by an updraft, the mosquitoes that bite people don't fly higher than 25 feet.
Secondly, mosquitoes in general are poor fliers. Any sort of breeze blows them away.
And these mosquito-vectored diseases are in the US. Dengue is in Florida, south Texas and southern Californa (and the Bay Aera). Zika is too (and in CR has been more of problem in Jaco due to poor individual vector control). Chikungunya is in the US too (that was last years "OMGWTFBBQ!" disease - this year it is Zika, which has been known for 70 years and never showed a causational link with microcephaly until the Brazilians decided it did).
And the first human case of Zika was in Africa in 1952. There were outbreaks in the Pacific in 2007 and 2013.
Zika is no threat to most people. Obviously until the causational allegation with microcephaly is proved or disproved it is prudent for pregnant women or women desiring to get pregnant to take precautions. The 'sexual contact' appears to be limited to male-to-female and there isn't a literature that I'm aware of of how long the infected male is a carrier (the CDC says 8 weeks).
If you are afraid of getting a mosquito-vectored disease, then smear on DEET, treat your clothes with permathion, stay indoors with the AC on and don't go
anywhere - because these diseases are in the US.
