Another thing...
When someone gives you a forecast with as big a deviation between the high and low as this one is...they are sheeting in the wind...and really have no idea..
“The Ebola outbreak could skyrocket to between 550,000 cases and 1.4 million cases by 2015”
It all depends on how well people decide to follow the rules of quarantine.
If someone with Ebola were to spend one day infecting people who pass through the Chicago airport, how fast would it spread through the USA?
