Bad time to have some of those disease in the US. The Asian tiger mosquito can spread some of those including denge fever. Those mosquitos are as far north as NJ. You will know that mosquito by its ridiculous size and aggression. Its 4-5 times the size of native species and they are known disease spreaders.
We had an outbreak of the Asian Tiger mosquito when I lived in Wilmington, NC. They laughed at big spray. They would bite right through my Converse high tops. It would take two or threw whacks to kill the little monsters and they would leave a pile of blood. Things are just nasty.
