The disease spreads by people touching the body fluids of an infected person. No medicine or treatment now exists for the disease.

The scientists gave eight monkeys a small but deadly amount of the Ebola virus. They gave an experimental vaccine (疫苗 ) to only four of them. The monkeys that did not receive the vaccine died within a week. The vaccine prevented the disease from developing in the four monkeys that received it. All the four monkeys were healthy six months later. The researchers said this was the first time a vaccine had protected animals similar to humans from the deadly Ebola virus. They will continue to test the vaccine on animals by giving them increasingly strong amounts of the virus. 56. The first symptom of Ebola hemorrhagic fever is ______.
