Who knows. Writebol got infected, and I’m pretty sure she took extensive precautions. It may already be able to go airborne, but in a very limited sense. I also doubt that Ebola has as much coughing and sneezing as the flu or cold, so aerosol droplets containing the virus might simply be much rarer.
Q: Were you wearing PPE in your job, disinfecting doctors and nurses?
N.W.: No, I was wearing gloves and a disposable apron. There were times I had a mask on. I was behind a line where I did the disinfecting. They were on one side of a line and I was on the other side. I never crossed those lines. We just don’t even have a clue what happened.
