Health officials keep saying ebola is 100% contracted through bodily fluids why is that?

If it is only passed through bodily fluids, how did the 2nd case in Dallas, a health worker contract the disease from the man who died from ebola in Dallas? Sneezing counts as body fluid correct? Same thing with a good hard cough, there is saliva and some phlegm flying around right? How did this woman break protocol? Did she drink from the mans cup? Kiss him? Or what?

They keep stressing ebola isn’t contracted through the air. Which at this point is complete bullshit.
