An experimental vaccine(E H)developed to prevent outbreaks of Marburg(马尔堡病毒) hemorrhagic(出血的) fever continues to show promise in monkeys as an emergency treatment for accidental exposures to the virus that causes the disease. There is no licensed treatment for Marburg infection, which has a high fatality rate In a study of rhesus macaques (Ei a), 5 of 6 monkeys survived a fatal dose of Marburg virus when treated 24 hours after infection, and 2 of 6 survived when treated 48 hours after infection. Because rhesus macaques typically die of Marburg infection faster than humans, the post-exposure treatment window might be extended even further in humans, the study authors say The study, overseen by a scientific team from the National Institutes of Health and three other groups with expertise in viral hemorrhagic fevers, was posted online by the journal Emerging Infectious Diseases Developing safe, effective, and rapidly effective post-exposure treatments for filoviruses (丝状病毒) is an important scientific priority for our Institute," says Anthony S. Fauci,MD director of NIHs National Institute of Allergy and Infectious Diseases(NIAID)."The vaccine used in this study is among several novel approaches to treating filoviruses that show great The fact that three of the rhesus macaques in the current study showed evidence of Marburg virus in periodic blood tests, but later cleared the virus from their systems and survived, is particularly satisfying to Dr. Feldmann and Tom Geisbert, Ph. D of Boston University. In addition 14 days after infection, all of the rhesus macaques that survived showed moderate to high levels of antibodies(if)against Marburg virus. The scientists view this as proof that the vaccine worked 29. What would be the best title of this passage? A. Evidence of Marburg Virus in Periodic Blood Tests B.
