刚果民主共和国的埃博拉疫情已演变成全球历史第二大疫情。截至7月31日，该国官方确认了3,532例感染和1,556例死亡[1]，超过了该国2018-2020年最严重疫情的感染总数[1]。这场疫情仅次于2014年至2016年西非疫情[1]，而该次西非疫情共造成28,616例感染[1]。
当前疫情的传播速度异常迅猛[1]。联合国粮食计划署官员Carl Skau指出，"这是我们所见过传播最快的埃博拉疫情"[1]。疫情的前三个月致死人数是以往疫情同期的五倍[1]，且病例数在7月15日突破2,000例后，仅几周内便攀升至3,500例以上[1]。疫情已跨越该国五个省份[1]。
导致此次疫情的Bundibugyo病毒株目前尚无已获批疫苗或治疗方法[1]。新加坡希里曼实验室开发的候选疫苗已被世界卫生组织评为"最有前景的候选疫苗"[1]。与此同时，牛津大学也在开发针对该病毒株的疫苗，并于上周开始首位志愿者的接种工作[1]。
The Democratic Republic of Congo's Ebola outbreak has surpassed the total infection count from the country's previous most severe epidemic, making it the second-largest Ebola outbreak in global history.[1] As of July 31, officials confirmed 3,532 cases and 1,556 deaths.[1] The outbreak has spread across five provinces and demonstrates an exceptionally rapid transmission rate, with deaths in the first three months running five times higher than comparable periods in previous epidemics.[1] Only the 2014-2016 West African outbreak, which recorded 28,616 cases, remains larger.[1]
The current outbreak involves the Bundibugyo virus strain, for which no approved vaccines or treatments currently exist.[1] However, vaccine development efforts are underway. The Shriemann Laboratory's candidate vaccine has been evaluated by the World Health Organization as "the most promising candidate vaccine."[1] Oxford University is also developing a Bundibugyo vaccine, with the first volunteer receiving an inoculation last week.[1] A WHO official characterized the situation, stating: "This is the fastest-spreading Ebola outbreak we have ever seen."[1] The rapid escalation of cases underscores the severity of the crisis, with confirmed cases reaching 2,000 by mid-July before climbing to over 3,500 within weeks.[1]
