More and more of the US is going to be a tropical climate and will have to deal with tropical diseases in the coming decades. We'll need to stop pretending the Gulf is substantially different than Central America in ecology pretty soon, including for diseases.
The best time to get serious about fighting back against these diseases was generations ago. Of course, capitalist systems didn't care about suffering and death that didn't effect the bottom line, but as the threats loom closer they finally get off their haunches. Any progress on it is good.
