Most of the lack of caution concerns the behavior of the Ebola host. They are thinking that Ebola is infectious when the host is peaking from fever. When the host is most infectious, he is too sick to be out in public. Those who they do infect are those who try to take care of them as they puke everywhere. At that time, I believe that the aerosol action of a toilet as it flushes vomit and diarrhea would contaminate surfaces with infectious Ebola. How long those surfaces would be infectious would be a matter of concern.
Misting with Clorox will kill most of the bacteria I am quite certain.
