The findings, published in the US journal Science Translational Medicine, suggested that it may be possible to develop a cure for Ebola, even after the virus is detected in the blood and disease symptoms have become apparent. Although rare, Ebola virus is considered as one of the most aggressive viruses because of its rapidity of death, which can be one week from exposure, or three to four days from the time the first symptoms become apparent. “For this reason, such a treatment has been considered to be closer to the field of science fiction than contemporary scientific research,” said lead author Qiu Xiangguo at the Public Health Agency of Canada. In their study, the researchers gave Ebola-infected monkeys a treatment made of three specific antibodies(抗体) in combination with interferon-alpha (a 干扰素), which is produced naturally by the body to fight viruses. Once in contact with outer regions of the virus, these antibodies can reduce the ability of the virus to reproduce. At the same time, the interferon-alpha increases the defense of the infected individual by stimulating a natural but rapid and powerful anti-viral response, she said. “Although we were very optimistic, we were not expecting to see 100 percent survival of Ebolainfected monkeys, when they are treated only three days before they die of the disease on average,” Qiu said. “This study shows that what seems impossible for many to develop a cure capable(有能力的) of stopping Ebola virus only a few days before death, has now been made and proven to be effective,” she added. 41.
