This article in the NY Times is a very interesting read. As a student of molecular biology, I think it is very important to spread awareness of terrifying disease epidemics like this one, which has very easily got the potential to become a pandemic, given the highly globalized world we live in.
It takes some data from the Centers for Disease Control and Prevention, and anecdotal reports from the region to give you a real perspective on the spread of the disease. As to the pathogenesis, you have to read elsewhere for more information on that. Enjoy!
