It does seem that early casual contact is not very contagious. They will be fine. The only case that makes me worry is the cameraman who may have gotten it from washing a car.
I think blood donor precautions should be taken about Ebola.
The camera man was released yesterday, no?
Research doesn’t rule out transmission by floating droplets
During a 1995 outbreak of Ebola in Kikwit, Congo, a team of scientists studied 316 people diagnosed with the disease. For the vast majority, there was an explanation of how they contracted the disease. They had a history of very close contact with a patient and body fluids, many of them in a hospital where patients were being treated.
But for 12 people there was no clear explanation of how they had become infected, said Dr. C.J. Peters, a virologist at the University of Texas Medical Branch at Galveston. He headed the research team when he worked for the CDC.
Because there was no evidence that those 12 people had been close to an Ebola patient, the researchers said they had to consider such possibilities as droplets containing virus, airborne virus particles or the touching of a contaminated object.
“We believe there is scientific and epidemiologic evidence that Ebola virus has the potential to be transmitted via infectious aerosol particles both near and at a distance from infected patients, which means that healthcare workers should be wearing respirators, not facemasks.“
