I’m skeptical too that it is airborne. Currently it is still spreading slowly but fairly consistently compared to stuff like flu... the number of cases is roughly doubling each month. 1,600 cases now, about 800 this time last month.
If it was airborne, that number would go up MUCH faster. However, in late 2012, it was shown that it could be transmitted airborne in the close-quarters conditions of a laboratory between animals.
Worse case scenario would be if a patient with another RNA virus like norovirus (with similar early symptoms) got put in with the ebola patients and the virus acquired some of the supercontagiousness of noroviruses...
If it was airborne then the results would be exponential.
Lab rats? All can catch it by bumping noses.
This like other things has the fear mongers spinning the facts already. Has aids gone airborne? Hepatitis C? Obama?
