Not just for the tropics of course, historically Washington/Philadelphia areas were rancid w/ malaria. Being smart is what's needed. Heavy military traffic w/ thousands shuttling back'n'forth between Ebola areas and the entire U.S. to is not smart.
I wonder if the 1918 Influenza Pandemic that killed 20 million worldwide and was spread by the Troopers traveling back and forth between the continents rings a bell with Obama. But no worries because Ebola is not airborne and the flu is. : )

In 1994 I took a road trip from Chicago through many of the Southern States. I drove the Natchez Trace which is a super secret National Park. The Trace began in Natchez, Mississippi and ended between Nashville and Franklin, Tennessee. It was the first immigration path into the US where people were needed to populate Tennessee and Kentucky. There are some very interesting stops along the way (Louis from Louis and Clark fame, committed suicide in a Stand (Inn) along the trace). One stop had the remains of a town that disappeared in a single summer due to a yellow fever outbreak. Yellow Fever - I was amazed. Now the greenie-weenies are having us bring back wetlands that our great grand fathers did away with for very good reasons. I call these wetlands Mosquito Farms. Oh well.
