The treatment is indirect life support, IV fluids, adjust electrolyte balance, maintain oxygen & blood pressure, and treat other secondary infections if they occur. Most people die from dehydration due to vomiting & diarrhea and the subsequent kidney, liver or multi-organ failure.

There is no direct pharmaceutical treatment. Zmapp is experimental and there is very little of it around. It consists of a mixture of three monoclonal antibodies, originally made in mice and 'humanized' by recombinant genetic methods so they can be injected IV. These neutralizing antibodies seem to provide passive immunity. They clear viral particles from circulating blood. It worked in a test of about 18 monkeys, and probably works in humans, but it hasn't been tested enough to provide any data where efficacy and safety can be determined. Only 2 humans have received it.
Active immunity would come after recovery from an Ebola infection, or from a vaccine made from inactivated Ebola virus. People (GSK and USAMRID) are working on several different vaccines now.
ZMapp - Wikipedia, the free encyclopedia
The Canadian drug is a similar mixture of antibodies to Zmapp, but they are not humanized. Injecting mouse antibodies can work, but only once. If you inject them a second time, you develop an anti-mouse immune response, which can have severe, even life threatening, effects.
