Simone as to my point... Don't you think at this point of the matter, when you become contaegeous is probably just as important as weither it would be airborn?
If you are not contegous till after you show signficant symptoms, we have a very good chance of isolating patients and getting the outbreak undercontrol.
IMO arguing about it being airborn is a strawman. There are many non airborn illness that spread VERY well. Some research suggests that even flu isn't truely airborn but droplet (just like ebola). Also evidence suggests that you shed the virus in your sweat... that would give ebola an advantage that many other viruses don't have. Also ebola probably can gain infection through numerous ways... with respitory infections you probably have to get the virus into your respritory tract.
The virus can very clearly become airborn atleast for short periods of time. However... since respitory infection isn't a symptom normally seen early in the illness it is very unlikely that the patient sheds in an aerosol matter. However vilolent vomiting and stooling probably can create an areosol. Also many medical procedures probably can create an areosol.
