联合国9月25日电——据路透社报道，一名非洲卫生高级官员称，正在抗击刚果民主共和国埃博拉疫情的卫生当局，仅确定了约3万名可能接触病毒者，而预计通过接触者追踪需要确定的人数超过40万，前者只是后者的一小部分。
UNITED NATIONS, Sept 25 - Health authorities battling the Ebola outbreak in Democratic Republic of Congo have identified only about 30,000 people who may have been exposed to the virus, a fraction of the more than 400,000 expected through contact tracing, a senior African health official told Reuters.
非洲疾病控制与预防中心总干事让·卡塞亚博士说，这一缺口表明，尽管疫情控制取得了一些进展，但疫情仍在社区中持续蔓延。
Dr. Jean Kaseya, director-general of the Africa Centres for Disease Control and Prevention, said the shortfall showed the outbreak remained entrenched in communities despite signs of progress.
超过80%的新确诊病例是在原本不在接触者名单上的人群中发现的，这表明病毒传播仍发生在监测工作触达不到的范围之外。
More than 80% of new confirmed cases were being detected among people who were not already on contact lists, suggesting transmission is still occurring beyond the reach of surveillance efforts.
卡塞亚周五在纽约联合国大会会议间隙告诉路透社，对于每一例确诊埃博拉病例，卫生当局预计需要确定约60名与患者有过直接或间接接触的人。
For every confirmed Ebola case, health authorities would expect to identify about 60 people who had direct or indirect contact with the infected person, Kaseya told Reuters on Friday on the sidelines of the UN General Assembly in New York.
按约7000例确诊病例计算，对应的接触者应约为42万人。卡塞亚说：“但目前，我们的接触者名单上只有3万人。”他补充道：“当疫情处于社区层面时，我们就谈不上控制疫情。”
With roughly 7,000 confirmed cases, that would translate into about 420,000 contacts. "But currently, we have just 30,000 people in the contact list," Kaseya said. "When the outbreak is at community level, we cannot talk about control," he added.
此次埃博拉疫情于5月被发现，规模已成为有记录以来第二大，仅次于2014年至2016年发生在西非的疫情。
The Ebola outbreak was detected in May and is already the second largest on record, behind one in West Africa from 2014 to 2016.
疫情扩大 世界卫生组织周五表示，疫情已扩散至两个新增卫生区：南乌班吉省的布卢卫生区，以及靠近南苏丹边境的上韦莱省栋杜卫生区。这使横跨七省的受影响卫生区总数增至63个。
OUTBREAK SPREADS The World Health Organization said on Friday the outbreak had spread to two additional health zones, Bulu in Sud Ubangi province and Dungu in Haut-Uele province near the South Sudan border, bringing the number of affected health zones to 63 across seven provinces.
上周，联合国及刚果政府官员表示，在疫情震中伊图里省一些受灾最严重的地区，病毒传播已出现放缓迹象。
Last week, United Nations and Congolese government officials said there were signs transmission was slowing in some of the worst-affected parts of Ituri, the epicenter of the outbreak.
刚果总理朱迪丝·苏敏瓦·图卢卡周三称，这场疫情是对该国的一次重大考验，并表示应对工作已经开始取得切实成果。“我们看到了一些好转，但疫情依然严重，”卡塞亚说。
Congolese Prime Minister Judith Suminwa Tuluka described the outbreak on Wednesday as a major test for the country and said the response had begun producing tangible results. "We see some improvement, but the outbreak is still serious," Kaseya said.
卡塞亚表示，即便刚果每天仍新增50起、60起或70起病例，如果这些患者是已被识别并作为接触者进行监测的人员，他的担忧也会减少，因为这意味着卫生部门知道传播发生在何处。
Even if Congo were still recording 50, 60 or 70 new cases a day, Kaseya said he would be less concerned if they were people already identified and monitored as contacts because it would mean health authorities knew where transmission was occurring.
卡塞亚拒绝预测疫情何时能得到控制，他表示，在为应对工作设定时间表之前，他希望看到监测工作取得实质性改善以及其他方面的改进。
Kaseya declined to predict when the outbreak would be brought under control, saying he wanted to see substantially better surveillance and other improvements before putting a timetable on the response.
“如果要说自我宣布此次疫情爆发以来我最不想玩的游戏，那就是预测我们何时能控制住这场疫情，”他说。
"If there is a game I didn't want to play since we declared this outbreak, it was to predict when we can bring this outbreak under control," he said.
卡塞亚表示，如果在接触者名单中发现了新的确诊病例、社区中没有出现死亡病例、且医护人员中没有发生新的感染，他或许就能预测疫情是否能在四周内得到全面控制。
Kaseya said if new confirmed cases were identified through contact lists, zero deaths were occurring in communities and there were no new infections among healthcare workers, he could be in a position to forecast whether the outbreak could be fully controlled within four weeks.
但他说，就目前而言，在接触者名单之外发现的病例比例仍然很高，这证明社区传播尚未得到控制。
But for now, he said, the high proportion of cases being discovered outside contact lists remained evidence of uncontrolled community transmission.
非洲疾控中心表示，周四在纽约召开的一次由美国召集的会议上，各方为埃博拉应对工作认捐了近29亿美元，其中包括来自美国的8.86亿美元。
Africa CDC said nearly $2.9 billion was pledged for the Ebola response at a US-convened meeting in New York on Thursday, including $886 million from the United States.
