乌干达出现由苏丹型埃博拉病毒引发的埃博拉病毒病暴发

乌干达在 2022 年 9 月 20 日宣布苏丹型埃博拉病毒病暴发。这是乌干达自 2012 年以来由苏丹型埃博拉病毒引发的首次疫情暴发。

截至 2022 年 11 月 7 日,已报告 136 例确诊病例,包括 53 例确诊死亡病例(病例死亡率为 38.9%)。据报告,医务工作者中已确诊 18 例病例和 7 例死亡病例。当前,超过 1300 名接触者在乌干达 7 个区接受监测,其中受影响最严重的是穆本德区。

世界卫生组织评估该次疫情暴发风险在国家层面为“极高”,在地区层面为“高”,而全球范围的风险为“低”。

当前可用的治疗方法和疫苗仅获批用于治疗和预防扎伊尔型埃博拉病毒病。目前正在研发针对苏丹型埃博拉病毒的候选疫苗,并考虑在乌干达展开随机对照试验进行测试。

先前苏丹型埃博拉病毒病暴发的病例死亡率为 53%-65% 不等,最大规模的一次暴发于 2000 年发生在乌干达(425 例)。苏丹型埃博拉病毒是继扎伊尔型埃博拉病毒之后导致疫情暴发的第二常见病毒属。
