Completely right! As was theorized since the first modern recorded index case was recorded in Africa (a Dutch coffee farm owner?), several healthcare providers were infected who had not even touched the patient or any of the patient's secretions.
However, note in the paper I cited:
"However, the isolation of EBOV from only 1 saliva specimen, in contrast to the 8 that were RT-PCR positive, could suggest that the virus is rapidly inactivated by salivary enzymes or other factors in the oral cavity that are unfavorable to virus persistence and replication."
That plus the fact that standard precaution PPE for diseases with high rates of transmission (at least in CA) calls for goggles and a mask makes this story all the more interesting.
