“Sanitise,” says the security guard outside a school in Nairobi, gesturing towards a dispenser(分配器). Since Kenya reported its first-ever case(首例病例) of the Ebola virus last month many venues in its capital have made visitors disinfect(消毒) their hands and get their temperatures checked. Officials tell people to avoid large gatherings(避免大规模聚集). “I want to appeal(呼吁) to Kenyans going forward(今后) that we can also avoid handshakes or hugging,” said Patrick Amoth, the director-general(总干事) at the health ministry. “We can just wave.”
“消毒，”内罗毕一所学校外的保安指着消毒液分配器说道。自上个月肯尼亚报告该国首例埃博拉病毒感染病例以来，首都的许多场所都要求访客对手部进行消毒并接受体温检测。官员们告诫人们避免大规模聚集。“我想呼吁肯尼亚人，今后我们也可以避免握手或拥抱，”卫生部总干事帕特里克·阿莫斯说，“挥挥手就行。”
The precaution(预防措施)s reflect growing concern(日益担忧) about the spread of an Ebola outbreak that emerged in the east of the Democratic Republic of Congo this year. The Kenyan case involved a businessman who had been living in eastern Congo but returned home to Kenya via Uganda on October 3rd.(肯尼亚的病例涉及一名商人，他此前一直居住在刚果东部，10月3日经乌干达返回肯尼亚家中。) He died two days later. Kenya has since reported eight more cases (and another death), all of them contacts of the first. On October 20th another of Africa’s largest economies, Nigeria, reported its first case of Ebola in a decade. A woman who had travelled to Uganda tested positive in Abuja(阿布贾，尼日利亚首都), Nigeria’s capital.
这些预防措施反映出人们对今年在刚果民主共和国东部暴发的埃博拉疫情蔓延日益担忧。肯尼亚的病例涉及一名商人，他此前一直居住在刚果东部，10月3日经乌干达返回肯尼亚家中。两天后他去世了。此后肯尼亚又报告了八例病例（以及另一例死亡），他们都是首例病例的接触者。10月20日，非洲另一个最大经济体尼日利亚报告了十年来首例埃博拉病例。一名曾前往乌干达的女性在尼日利亚首都阿布贾检测呈阳性。
Since the outbreak was officially declared in May there have been more than 10,500 confirmed cases of the gruesome(可怕的) and terrifying virus. Almost half (5,130) have so far resulted in death, with all but four(除四例以外全部) of the fatalities in eastern Congo. Fewer than a quarter of new cases there occur in patients who are known contacts of previous cases, says Jean Kaseya, the director of Africa Cdc, a public-health body.(非洲疾控中心主任让·卡塞亚表示，当地新增病例中，属于已知既往病例接触者的不到四分之一。) So long as authorities are in the dark about(对……一无所知) the virus, the epidemic will keep growing.
自5月正式宣布疫情暴发以来，这种可怕而骇人的病毒已造成超过1.05万例确诊病例。迄今为止，近半数（5130例）已导致死亡，其中除四例以外，所有死亡病例都发生在刚果东部。非洲疾控中心主任让·卡塞亚表示，当地新增病例中，属于已知既往病例接触者的不到四分之一。只要当局对病毒一无所知，疫情就会继续蔓延。
