世界卫生组织警告称，随着病毒从东非跨境传播至尼日利亚，标志着西非出现首例病例，非洲正面临一场“复杂”的埃博拉疫情。
The World Health Organization warned that Africa faces a "complex" Ebola outbreak after the virus crossed from East Africa into Nigeria, marking the first case in West Africa.
世界卫生组织周四表示，随着病毒从东非跨境传播至尼日利亚，确认了西非地区首例记录在案的病例，非洲正面临一场“复杂”的埃博拉疫情。卫生官员认为，这名尼日利亚患者在乌干达感染病毒，随后经由该地区继续旅行。
The World Health Organization said Thursday that Africa is facing a "complex" Ebola outbreak after the virus crossed from East Africa into Nigeria, confirming the first case recorded in the western part of the continent. Health officials believe the Nigerian patient contracted the virus in Uganda before travelling onward through the region.
此次疫情可追溯至刚果民主共和国早前的一次疫情反弹，此后已蔓延至肯尼亚和乌干达，给跨境疾病监测带来压力。非洲疾病控制与预防中心警告称，鉴于边境管控薄弱以及受影响国家间人员往来频繁，非洲大陆没有任何一个国家可以认为自身安全。
The outbreak traces back to an earlier flare-up in the Democratic Republic of Congo that has since spread to Kenya and Uganda, straining cross-border disease surveillance. Africa's Centers for Disease Control and Prevention has warned that no country on the continent can consider itself safe, citing porous borders and heavy travel between the affected states.
尼日利亚卫生当局已将确诊患者的密切接触者置于隔离观察中，并正与世卫组织团队合作，追踪中转机场的潜在暴露风险。官员表示，中非地区正在进行的疫苗试验为遏制进一步传播带来一些希望，但他们警告称，西非的医疗体系资源仍不足以应对持续的疫情。
Nigerian health authorities have placed contacts of the confirmed patient under quarantine and are working with WHO teams to trace possible exposures at transit airports. Officials say vaccine trials already under way in Central Africa offer some hope of containing further spread, though they caution that West Africa's healthcare systems remain under-resourced for a sustained outbreak.
