My question is - does anyone know at what point in the incubation/infection
stages of Ebola can the disease be spread?  We can be certain that contact
with the fluids of a person with a full blown ebola infection will result in 
the transmission of the disease.  What about before symptoms are exhibited?

Can someone contract ebola through contact with infected fluids and spread 
it through casual contact (even in confined quarters like what is found in an 
airliner) during early incubation stage?  Or is not enough known about its
transmission?

Forgive me if this is something I've missed in a previous post, I haven't been
able to read them all.
