I agree completely and it makes more sense that if she used a plain face mask or even a N-95 face mask, it didn't provide protection for fine aerosol particles. So, she could have followed all CDC protocols and still got infected. The CDC needs to recognize the danger from not using proper respirators when working closely with these patients. Of course, stating that method of transmission (airborne in aerosols) would cause panic by those who see everyone with a cough as an Ebola victim. Therefore CDC and the other doctors on the networks (including Fox) have to continue with the non-airborne meme in spite of increasing evidence to the contrary.
(BTW, I used an air-purifying respirator last year in clearing out Hanta-virus carrying deer mice from my garage. That virus is about 50-70% fatal to those contracting it.)
Good precaution. However, it isn't the mice that are the problem, it is their dried feces - which, like asbestos - deliver particles through the air once disturbed. Of course, I'd suspect that dried mouse bodies would do the same.
