 Dengue has been surging out of the expanding tropical areas of the world as tropical conditions push North and South from the Equator. 

The mosquitoes carrying Denge and a whole host of other diseases, and the diseases themselves have ridden the warm currents of climate warming into California, the Sierra, and the Northern Lattitudes.

We've seen a steady progression of tropical insects and diseases enter the US over the past twenty years as warming accelerates its effects.

The entry of the Asian tiger mosquito and Aedes aegypti into California presages the entry and spread of a number of terrible tropical diseases we are not going to enjoy at all.
