“Being at first skeptical that Ebola virus could be an aerosol-transmissable disease, we are now persuaded by a review of experimental and epidemiologic data that this might be an important feature of disease transmission, particularly in healthcare settings,” researchers at the University of Illinois/Chicago School of Public Health wrote last month.

On Saturday, President Obama stated that “Ebola is actually a difficult disease to catch. It’s not transmitted through the air like the flu.”

Dr. Tom Frieden, director of the Centers for Disease Control and Prevention (CDC), also said that “this is not like flu. It’s not like measles, not like the common cold. It’s not as spreadable, it’s not as infectious as those conditions.”
