If the Ebola virus can only be transmitted through bodily fluids (blood and vomit); I have to ask, how did the NBC cameraman contract the disease? The guy is reporting on a dangerous disease and is careless enough to come into contact with someone’s bodily fluids? Did all of the recent patients we hear about contract the disease through blood and vomit?
One likely option is walking in the wrong place. Ebola patients leak or even spray fluids from both ends. It ends up on the floor/ground, and it doesn't get decontaminated immediately (or ever) if the staff are overworked (and the typical West African medical worker is caring for 5-10 times the patient load they should see). Outside of hospitals/clinics, Ebola victims wait to get in, often contaminating the surrounding grounds. He probably stepped in it and then took his shoes/boots off at the end of the day. Game over.
