　　Scientists investigated why Ebola virus is so deadly when it spreads from animals to humans and then from human­to­human contact. The research team looked at the Zaire Ebola virus in an animal system to understand how it gains strength. This virus is responsible for the current outbreak in West Africa. They found that initially the animal systems were not affected by the virus, but succeeding transmission(传送) into other animals caused the virus to “hot up” and become more severe.

　　The team analyzed the viruses at different stages and were able to identify several changes in its genetic material that were associated with increased disease.

　　Professor Julian Hiscox, who led the study from the University's Institute of Infection and Global Health, explains: “The work tells us that the evolutionary goal of Ebola virus is to become more fatal.”

　　“We were able to show through genetic analysis which parts of the virus are involved in this process. The information we have gathered will now allow us to monitor for such changes in an outbreak as well as develop future treatment strategies.”

　　Professor Roger Hewson, leading the study from Public Health England, Porton Down, said: “Ebola virus is such a destructive infection to the people affected by the disease and the economy of West Africa.”
