I don't see it any different than malaria, caused by plasmodium and also a serious health problem in some parts of the world ( https://en.wikipedia.org/wiki/Malaria https://en.wikipedia.org/wiki/Malaria ): not all mosquitoes carry malaria, but the only way to eradicate malaria in some area is to manage to not have mosquitoes there, it's known since approximately the end of the 19th century, and still true. And the spreading of malaria has also different dynamics from the spreading of all of mosquitoes. So yes, the changes in environment that make for the insects to easy to spread in the areas where they couldn't before is something that should concern the humans, especially if there is a proof that humans helped the spread.
