There is no cure for Ebola. It's a virus, like a cold, so it has to run it's course. The only treatment is support--things like fluids to prevent dehydration and pain management.
There is an experimental drug that was used on those 2 Americans, but it was also given to the Spanish priest who died. He is the one who seems to have infected this Spanish nurse.
The supplies of that drug have run out and it takes months to make more.
Contrary to popular belief, this is not the first time the Ebola virus has been in this country. However, it is the first time it has infected humans in this country.
There was actually an outbreak in Reston, Virginia in a group of imported monkeys. I think it was in the 80's or 90's. It took some time for people to find out what the problem was and it's truly miraculous that no people caught it. They were very lax in their interactions with those animals, and we all know how unsanitary caged monkeys can be.
If anyone is interested in learning more about the virus, The Hot Zone is a very informative book and well worth reading.
I don't know if dogs can even catch or carry the disease. Maybe someone else has that information?
