One is a politicaaly-correct virus; the other is not. (Personally, I believe AIDS could be transmitted by a mosquito...why not?)

Not to nitpick, but you would get HIV not AIDS from the mosquito. Anyway, WNV and HIV are two different types of viruses, you can think of them as being analogous to two different species. HIV doesn't do well outside of the body, nor does it do well in the body of a mosquito. Most of your mosquito born viruses have evolved a rather interesting relationship with the mosquito that allows for their transmission from host to host (if you'd like more info on this, and it's fasciniating, I'll dig it up for you). HIV doesn't need this - humans seem to manage to have enough sex and shoot up enough drugs to pass the virus along just fine.
From the CDC:
"If HIV were being transmitted through other routes (such as through air, water, or insects), the pattern of reported AIDS cases would be much different from what has been observed. For example, if mosquitoes could transmit HIV infection, many more young children and preadolescents would have been diagnosed with AIDS."
