MSF says that while the virus is believed to be able to survive for some days in liquid outside an infected organism, chlorine disinfection, heat, direct sunlight, soaps and detergents can kill it.
"People who become sick with it almost always know how they got sick: because they looked after someone in their family who was very sick -- who had diarrhea, vomiting and bleeding -- or because they were health staff who had a lot of contact with a sick patient," she said.
How long can Ebola virus particles survive in a drop of blood on a surface outside the body?
A drop of blood can remain contagious outside the body. And virus particles can survive for days or weeks, depending on the environment. Ultraviolet light, heat and exposure to oxygen gradually deactivate the virus, while cooler temperatures and humidity help keep it active.
"Blood, once it's outside the body, contains all the virus it's ever going to contain," Schmaljohn adds. "It's all downhill from there [for Ebola]."So yes, there's a risk you can catch Ebola from a drop of blood on a table. But that risk diminishes over time as the blood dries up.
Can Ebola be spread through a drop of water or carried through the water system?
"[The virus] will not remain for a long time in the water," Gonzalez says. "It's not a very rich medium to protect the virus."
It's important, he adds, to remember that viruses aren't as resistant outside the body as bacteria are. Rather, they depend heavily on the cells of their host — animal or human — for survival.In water, the Ebola virus would be deactivated in a matter of minutes, Schmaljohn says. That's because each Ebola virus is encased in an envelope taken from the outer surface, or membrane, of a host cell.
So what about cells in water that are infected with Ebola? Could you get the virus from infected cells in contaminated water?
Infected cells don't live long inside a liquid that doesn't have the same salt concentration as in our bodily fluids.
Drinking water has a lower salt concentration than that found inside human cells. As water rushes inside the cell to balance the salt concentration, pressure builds ups. Eventually the cell bursts, killing the virus in the process.

CRAP! Daycare just called, I have to go get my 3 year old grandson, he is sick, running a fever, throwing up and has diarrhea!
Glad I have not been to Africa!
Be back soon and thanks for all the great finds and coverage everyone has done to keep us up to date on what is really happening!!! Be back shortly.
You're back! How is your grandson? My jaw sort of dropped when I read your post, seeing what the subject of the thread is.
I am back, he is sick but nothing a little sprite couldn;t help. I am sure it just a virus that little ones always seem to pick up this time of the year. Thanks for asking, he is watching cartoons and sipping sprite out of his sippy cup. His momma, who is doing her RN clinicals at the hospital today just called too to check on him.

Meanwhile, the World Health Organization wasn't given the Obama administration's talking points about how you can't get ebola by riding a bus. They now state the Mali ebola patient potentially infected many people because he rode a bus while symptomatic.
They are all starting to trip over themselves on this one.
The World Health Organization said on Friday the first confirmed Ebola patient in Mali had travelled by bus through the country while showing symptoms and there had been multiple opportunities for exposure involving many people.
