摘要
Humans have been fighting against the Ebola virus disease （EVD） since its first outbreak in 1976 in southern Sudan and Yambuku in Zaire which lies on the Ebola River. According to the data from the World Health Organization （WHO, 2014b）, the first outbreak claimed 431 lives in 1976, and the disease awoke transiently in Sudan three years later and then disappeared for 15 years afterwards. Following that, large outbreaks appeared in 1995 in Zaire with 250 deaths of people, 2001-2002 in Uganda with 224 deaths, 2002-2003 in Congo with 128 deaths, and 2007 in Congo with 187 deaths.
